( June 2015 ) It was introduced to the US by inventor Benjamin Franklin, who was the postmaster of Philadelphia, Pennsylvania. For this reason, many regard Philadelphia as the birthplace of street lighting in the US. The colonial - era streetlights were lit by candles placed inside a glass vessel, which kept the candle from being blown out by wind. Franklin 's design was four - sided, with four separate panes of glass, so that if one pane of glass was broken, the lamp did not need to be entirely replaced, and might not even blow out. After the invention of gas lighting by William Murdoch in 1792, cities in Britain began to light their streets using gas. The United States followed suit shortly afterwards with the introduction of gas lighting to Pelham Street in Newport, Rhode Island in 1803. Throughout the 19th century, the use of gas lighting increased. Some locations in the US still use gas lights. After Thomas Edison pioneered electric use, light bulbs were developed for the streetlights as well. The first city to use electric street lights was Wabash, Indiana. Charles F. Brush of Cleveland, Ohio wanted to publicly test his new invention the `` Brush Light '' and needed a city to do so. The City Council of Wabash agreed to testing the lights and on March 31, 1880, Wabash became the `` First Electrically Lighted City in the World '' as a flood of light engulfed the town from four Brush Lights mounted atop the courthouse. One of the original Brush Lights is on display at the Wabash County Courthouse. By the beginning of the 20th century, the number of fire - based streetlights was dwindling as developers were searching for safer and more effective ways to illuminate their streets. Fluorescent and incandescent lights became popular during the 1930s and 1940s, when automobile travel began to flourish. A street with lights was referred to as a white way during the early 20th century. Part of New York City 's Broadway was nicknamed the Great White Way due to the massive number of electric lights used on theater marquees lining the street.

During the 1950s, GE lit roadways with its Form 109 and, later, the popular Form 400. Westinghouse answered with the OV - 20 model. In 1957, a new breed of streetlight fixture was introduced ; the `` cobraheads ''. If viewed from beneath they resembled a cobra 's flared neck. Westinghouse dubbed its cobraheads the Silverliners, which remained in production over the next 25 years. The OV - 25 remains a popular streetlight fixture. GE later introduced its own cobrahead, called the M400. The original M400 is noted for its pointed front end that protrudes over its bowl - shaped diffuser ( also called a refractor ). The M400 was the OV - 25 's main rival. They carried 250 -- 400 watt bulbs and were common on Interstate highways and city boulevards. GE made the M250 which was exactly same design as the M400 but using plastic refractor made for 250 watt. The M250 production ended in 1960 replacing with a M250R. In 1964, Westinghouse produced an updated version of the OV - 25, with a more rounded look. Only the diffuser was left unchanged. In 1967, GE updated its M400 and M250 with its PowrDoor design. Gone was the protruding front end, and the new M400A and M250A were also more streamlined ( although the original M400 and M250R continued to be produced until 1970 ). In 1970, a split - door M400 was introduced that shared the M400A 's bodyshell but had a nonvented door held in place with a spring latch, while the M400A 's vented door was held in place with a bail latch. GE and Westinghouse also developed smaller fixtures. A miniature version of the M400 was made for suburban residential streets and alleys. That fixture was called the M250R which replaced the M250 which looked exactly like the M400 but with plastic lens and rated for 250 watt. In the same vein, Westinghouse offered three smaller Silverliners. The OV - 12 ( whose look resembles a miniature OV - 50 ) came out in 1960, and it became the companion model to the Canadian - market OV - 14B, which had been introduced in 1957. The OV - 14B looks like a smaller version of the 1957 - edition OV - 25. Both the OV - 12 and OV - 14B were replaced by the OV - 15 in 1965. These smaller fixtures carried 100 -- 250 watt light bulbs. The second - generation M400 and M250 were the first fixtures to sport the new high pressure sodium ( HPS ) lights that came out in 1966. The existing Silverliners could not handle these new lights, so Westinghouse developed a new OV - 25, as well as a new OV - 15. Both of these new Silverliners ( also known as TuDors, and seen as Westinghouse 's answer to GE 's popular PowrDoor series ) now had a flat bottom, and were n't nearly as popular as the originals. However, by 1975, all Silverliners, including the single - door OV - 15 and OV - 25, were available as HPS units. More new manufacturers entered the streetlighting industry. ITT ( also known as American Electric, or ITT / American Electric ) developed two new fixtures, the Model 13 and Model 25. The Model 25 was later the basis for a larger lookalike, the Model 327. All three fixtures had a boxy look that usually sported grinning diffusers, a nod to the OV - 15s and M250s. ( Of the three fixtures, only the Model 327 is still in production. ) The Model 327, along with GE 's M1000 and Westinghouse 's OV - 50, sported 700 -- 1000 watt lights ( see table ). Earlier versions of the M1000 and OV - 50 ( and, in very rare instances, the Model 327 ) are noted for having fins on top of the fixture. As newer ones were made, the fins were eliminated. Some well - known light fixtures came from the Line Material Company. In the 1960s, during the height of the mercury lights ' popularity, Line Material produced the Unistyle 400 and the smaller Unistyle 175. Both of these fixtures combined various characteristics of the Silverliners and GE M - series fixtures. When the sodium era began around 1970, the company ( by then, renamed McGraw - Edison ) produced the boxy, rectilinear, more simplified Unidoor 400 ( for metropolitan expressways and city boulevards ) and Unidoor 175 ( for smaller residential streets and alleys ). In 1982, the entire Silverliner line was discontinued, when Cooper Lighting bought Westinghouse 's streetlighting division. Today, Cooper still makes the OV - 50, now called the OVL. It also continues to manufacture the OV - 15 and OV - 25 models for sale in Canada. GE and Cooper continued to take streetlighting to new heights. GE was a pioneer in the full - cutoff arena, when it created a spinoff of the popular M400 and the rarer M250 in 1975. This fixture is noted for its pointed front end and lack of a diffuser. In addition, high - mast assemblies were developed for the light towers that were springing up along Interstate highways. In 1988, ITT / American Electric also created spinoffs of its Model 13 and 25. These new fixtures, called the 113 and 125, had a more - rounded look than their respective predecessors. They have become the most popular fixtures not manufactured by GE or Westinghouse. While the Model 125 continues production today, the Model 113 was replaced by the American Electric Model 115 in 2003. In 1992, ITT sold American Electric to Thomas & Betts. In 2001, Thomas & Betts sold the street lighting division to Acuity Brands, where it was then spun off as American Electric Lighting. In the mid-1980s, GE revamped its entire lineup. One, called the M400R2, had a flat bottom reminiscent of the third - generation Silverliners ; the other, now called the M400A2, retained the original 1967 design but no longer had the vented door that the previous model did. Also, the M250R2 featured a slightly flatter profile than the M250R it replaced, and the M250A2 now took on the boxy profile that was previously used by the M150. In 1997, the M400 underwent a total redesign, borrowing its styling from the Thomas & Betts Model 125. In 2008, GE resumed production of the M400A2 and M400R2, which were sold concurrently with the 1997 - edition M400 and M400A models until 2016. In addition to the 1997 M400s and M400As, there have been many instances of manufacturers copying off another maker 's luminaires to create their own : For example, the Hubbell RLG400 has a look that closely resembles the Thomas & Betts Model 25, and ARK Lighting has two distinct fixtures that reuse the designs of the M250As and M250A2s ( with the first example made to use 400 watt lamps, which the actual M250 series has never been equipped to handle ). More recently, teardrop lamps ( both existing and reproductions ) have been used in favor of cobraheads in both urban and suburban areas. They are usually complemented with bishop 's crook poles and more elaborate architectural elements. King Luminaire ( a division of the StressCrete Group ) manufactures these. In addition to the existing manufacturers, newcomers such as Leotek have begun to make LED cobrahead luminaires to replace those that have used MV or HPS lamps. Electric light generation methods Arc lamp Open Arc lamps were used in the late 19th & early 20th century by many large cities for street lighting. Their bright light required that the early arc lamps be placed on rather high ( 60 to 150 - foot ) towers ; as such, they might be considered the predecessor to today 's high - mast lighting systems seen along major highways. They were also widely used in film and stage. Arc lamps use high current between two electrodes ( typically carbon rods ) and require substantial maintenance. Arc lights have mainly been used where high lumen light was needed such as lighthouses. Today very few open arc lights remain in operation, primarily in a few lighthouses and some industrial uses. The only remaining examples of original street lighting use are the moonlight tower of Austin, Texas. A xenon lamp is a high pressure sealed arc lamp, and is in common usage today where extreme brightness in a relatively small space is required, typically in motion picture projectors in theaters, and stage and motion picture lighting. They are also found in car headlamps. The sealed arc lamps do not suffer from the inefficiency and high maintenance problems of the original open arc lamps, but they are not well suited for most street lighting use. Incandescent light Incandescent lights using a tungsten filament were the first low power electric lights in cities worldwide and introduced some 20 years after open arc lamps. Some can still be found in streetlight service. Others have been installed in popular downtown areas of major cities to have a nostalgia effect. Incandescent light has excellent Color rendering index rated at 100. Color temperature is generally around 2000 -- 3200 K depending on the type of lamp and replaced the higher maintenance arc lamps. An incandescent light bulb is less efficient when compared to High - intensity discharge lamp and gas discharge lighting such as Neon light and are being replaced by more efficient CFL light bulbs or converted to MV or HPS. Tungsten - halogen incandescent lights which are brighter and more efficient and are very commonly used in theatrical and motion picture lighting and better color temperature characteristics are little used in street lighting due to their relatively short lifespan. Standard incandescent lamps are very commonly used in traffic signals, although they are increasingly replaced by LEDs. Fluorescent lamp The fluorescent lamp first became common in the late 1930s. These lamps are a form of discharge lamp where a small current causes a gas in the tube to glow. The typical glow is strong in ultraviolet but weak in visible light. The glass envelope is coated in a mixture of phosphors that are excited by the ultraviolet light and emit visible light. Fluorescent lamps are much more efficient than incandescent lamps, and for a short time became popular in street lighting both because of the efficiency and the novelty value. Fluorescent lamps for street lighting were first introduced to the public for commercial uses at the 1939 World 's Fair. The major problems with standard fluorescent lamps for street lighting is that they are large, and produce a diffused non-directional light. They are also rather fragile. Therefore, the fixtures needed to be large, and could not be mounted more than 20 -- 30 feet above the pavement if they were to produce an acceptable light level. Fluorescent lamps quickly fell out of favor for main street lighting, but remained popular for parking lot and outside building illumination for roadside establishments. Mercury vapor Example of a mercury vapor streetlight In 1948, the first regular production mercury vapor ( MV ) streetlight assembly was developed. It was deemed a major improvement over the incandescent light bulb, and shone much brighter than incandescent or fluorescent lights. Initially people disliked them because their bluish - green light made people look like they had the blood drained from them. Other disadvantages are that a significant portion of their light output is ultraviolet, and they `` depreciate '' ; that is, they get steadily dimmer and dimmer with age while using the same amount of energy, and in a few rare instances, they also cycle at the end of their life cycles. Even rarer is they can burn out, especially when the light is being burned while dim ( usually at the end of the life cycle ). Mercury lamps developed in the mid-1960s were coated with a special material made of phosphors inside the bulb to help correct the lack of orange / red light from mercury vapor lamps ( increasing the color rendering index ( CRI ) ). The UV light excites the phosphor, producing a more `` white '' light. These are known as `` color corrected '' lamps. Most go by the deluxe ( DX ) designation on the lamp and have a white appearance to the bulb. Mercury Vapor Bulbs come in either clear or coated with powers of 50, 75, 100, 175, 250, 400, 700 or 1,000 Watts. The Mercury Vapor lamp is considered obsolete by today 's standards and many places are taking them out of service. As of 2008, the sale of new mercury vapor streetlights and ballasts was banned in the US by the Energy Policy Act of 2005, although the sale of new bulbs for existing fixtures do continue, but the bulbs were also banned in 2015 in Europe. Mercury vapor fixtures can be operated with metal halide lamp ( MH ) ballasts, and are likely to be rewired with these ballasts in coming years. In response to the ban, some older MV streetlights will most likely be modified to use either high pressure sodium or metal halide lamps in the near future, because they are known to last longer than newer luminaires. In some areas where the MV lights are either failing or being replaced, they are being replaced by either HPS, LED, or Induction fixtures of similar lumen output, but also lower wattages and power consumption as well. High pressure sodium Example of a high - pressure sodium vapor streetlight Around 1970, a new streetlight was invented : The high pressure sodium ( HPS ) light. They became common in the late 1980s. It was initially disliked by most residents because of its orange glow, but the sodium vapor streetlight has since become the dominant type on American roadways and most people have become accustomed to the orange / yellow glow. It is by far the most efficient light source available. Color - corrected sodium vapor lamps exist but are expensive. These `` color corrected '' HPS lamps have lower life and are less efficient. There are two types of sodium vapor streetlights : high - pressure ( HPS ) and low - pressure ( LPS ). Of the two, HPS is the more - commonly used type, and it is found in many new streetlight fixtures. Sometimes, older ( pre-1970 ) fixtures may be retrofitted to use HPS lights as well. Virtually all fixtures that are converted to HPS have previously been lit with mercury vapor. Examples of retrofitted fixtures for HPS use include the GE Form 400, first generation GE M400 and M250 and the second - generation Westinghouse OV - 15 and OV - 25 Silverliner ( although later versions of this model were available from the factory as HPS units ) as well as the Line Materials Unistyle 400 and 175 / 250. LPS lights are even more efficient than HPS, but produce only a single wavelength of yellow light, resulting in a CRI of zero, meaning colors can not be differentiated. LPS lamp tubes are also significantly longer with a less intense light output than HPS tubes, so they are suited for low mounting height applications, such as under bridge decks and inside tunnels, where the limited light control is less of a liability and the glare of an intense HPS lamp could be objectionable. Many LPS lights are also being changed out to HPS using FCO fixtures, or going to LED. HPS lamps have slightly different electrical requirements than do the older MV lamps. Both HPS and MV lamps require a transformer or ballast to change the voltage and regulate the current, however, HPS lamps also require an electrical `` starter '' circuit -- much like older fluorescent lamps in residential use. MV lamps do not require a separate `` starter '' circuit because they have a special starter element within the bulb used for striking the arc. MV lamps slowly dim over time, and a 20 - year - old lamp may emit a very pleasing, but useless, soft green glow, rather than the powerful blue - white light of a new MV lamp. The yellow - spectrum HPS lamps also slowly dim over time but are known for `` cycling, '' where the lamp cycles on and off when it has reached the end of its life cycle. When cycling, the arc within the lamp extinguishes and the lamp must cool down before the starter circuit initializes a new arc. This has been the most recognized downfall of HPS. Some HPS lamps start to burn a pinkish / reddish color at the end of their life ( usually when already cycling ), or start to burn a pinkish / white color and go dim, or also burn out at the end of their life cycle whether they cycle or not. HPS fixtures can contain a special photocell or ballast that can sense a cycling lamp and shut off the fixture to prevent damage to the ignitor and ballast. HPS lamps generally have the same rated lifespan as MV lamps, and they give increased light and efficiency at lower wattages. Usually, when an MV light is replaced, it is replaced with a HPS light of a lower wattage, for example, a 175 watt MV fixture will get replaced with a 100 or 150 watt HPS fixture as that will meet or exceed the lumen output of the 175 watt MV fixture. At end of life MV lamps just become dimmer and sometimes color shift towards the green end of the spectrum but continue to consume the same amount of electricity. HPS lamps begin to suffer end - of - life cycling before the amount of useful light becomes visibly diminished, or just burn out. HPS lights come in wattages of 35, 50, 70, 100, 150, 200, 250, 310, 400, 600, 750, and 1,000 watt sizes, while LPS lights come in wattages of 18, 35, 55, 90, 135, and 180 watt sizes Metal halide In recent years, metal halide lamp ( MH ) streetlights have illuminated roadways and parking lots. Metal halide has long been popular in business installations and can be found in warehouses, schools, hospitals and office buildings. Unlike the old mercury lights, metal halide casts a true white light. It is not nearly as popular as its sodium counterparts, as it is newer and less efficient than sodium. Metal halide lights have also been used for retrofitting. Virtually all fixtures that are converted to metal halide have previously been lit with high - pressure sodium ( HPS ). Examples of retrofitted fixtures for metal halide use include the Thomas & Betts Model 25 and Model 327, as well as full - cutoff versions of GE 's M400. MH lamps suffer color shift as they age though this has been improving. Actual life expectancy is about 10,000 to 12,000 hours on average. There has also been a noted issue with the lamps `` exploding / shattering '' during a failure. Metal Halide light bulbs also tend to dim and / or flicker at the end of their life cycles, and on occasion, cycle. Sometimes, they emit a pinkish glow at or near the end of their life cycle which in this case, the bulb just burns out. High cost and low life hours has kept them from becoming popular municipal lighting sources even though they have a much improved CRI around 85. Therefore, the use of metal halide is limited mainly to city and high end street lighting. They are available in clear or coated bulbs. Probe start MH lights ( which are less efficient and are also soon to be banned, unlike Mercury Vapor lamps ) come in wattages of 50, 70, 100, 175, 250, 400, and 1000 watt sizes, while pulse start MH lights come in sizes of 50, 70, 100, 150, 200, 250, 320, 350, 400, 450, 750, and 1,000 watt sizes. The wattages of pulse start metal halide lamps are similar to HPS lamp wattages. Ceramic discharge metal halide lamp Ceramic discharge metal halide lamps promised to be the next step in streetlighting, replacing old mercury vapor and high pressure sodium lamps, especially where a more clear white with better CRI ( 78 -- 96 ) and light color retention was desired. CDM lamps give five times more light than comparable tungsten incandescent light bulbs ( 80 -- 117 lm / W ). However, continuing refinements in LED technology have now surpassed most other lighting types. Induction lamp An induction lamp features extremely long lamp life ( 100,000 hours ), energy efficiency, high color rendering index, and a color temperature close to incandescent lights. The life of induction ( also known as electrodeless fluorescent ) lamps is negatively affected by heat, particularly as the temperature exceeds 35 degrees Celsius ( 95 degrees Fahrenheit ). Since temperatures in this range commonly occur during early night hours in the summer in much of the US, induction lamp applications have not extended beyond test and demonstration projects for street lighting. The larger size of the induction lamps also inhibits the effective control of the light they emit, limiting their use to lower mounting applications. In 2009, PSEG in New Jersey began using induction lighting from US Lighting Tech, Inc ( Irvine, CA ) to replace very old and even some pre-2008 mercury vapor lights, and have had success in their reliability and output of the fixtures. Unfortunately, some failed induction lights were spot replaced with the HPS lights that were being removed to begin with and many new installs, PSEG is still using HPS. An updated design of the induction lights is now being used and these seem more reliable and brighter than the original design. Beginning in September 2011 the City of San Diego, CA will replace some 35,000 street lights with induction lamps costing $16,000,000.00. In Mexico, the city of Linares and Acapulco also have begun the replacement of 6,500 and 42,000 street lights with induction lamps from Amko SOLARA Lighting ( Taipei, Taiwan ), selected for their smart controls, since October 2011. A portion of these street lights from Amko will feature smart grid compatibility to allow the lights to be remotely monitored and controlled via the Internet. Compact fluorescent lamp Compact fluorescent lamps ( CFL ) have been used more frequently as time has improved the quality of these lamps. These lamps have been used on municipal walkways and street lighting though they are still rare at this time. Improvements in reliability still need to be made. Some issues with them are limited lumen output, high heat build up in the self - contained ballast, low life / burnout due to frequent cycling ( on / off ) of the lamp, and the problem where most fluorescent sources become dimmer in cold weather ( or fail to start at all ). CFL efficiency is high and CRI is excellent around 85. CFL produces a color temperature around 3000 K with its light being `` soft white '' around that color temperature. Higher color temperatures are available. Light emitting diodes Example of an LED streetlight Light emitting diodes ( LED ) have virtually replaced both incandescent lamps and the occasional fluorescent lamp in traffic signal and crossing sign usage. They are rapidly developing in light output, color rendering, efficiency, and reliability. The cost of LED lighting is still high compared to an incandescent or arc - discharge lamp used for the same purpose, but the cost is decreasing rapidly. Even with the high per - unit cost, the increase in efficiency and increased lifespan make them very attractive for street lighting use. The reduced cost of electricity and maintenance in some cases can offset the increased cost of the lamp. LEDs are increasingly finding widespread usage in general street, sidewalk, or parking lot illumination as technology improvements bring their brightness and cost into competition with HPS, MH, or CFL lighting. For example, the city of Ann Arbor, Michigan, implemented LEDs in street lighting applications in March 2006 and have since expanded their use. In addition Chapel Hill, North Carolina, entered a 12 - month test program and partnership with Duke Energy on March 25, 2009, to evaluate the effectiveness of replacing existing HPS lighting with the more efficient LED street lighting within its vibrant downtown. In late 2008, Anchorage Alaska installed over 4,000 LED streetlights as part of a plan to convert the community 's 16,000 roadway lights to efficient white light. In mid-2009, the City of Los Angeles announced a 5 - year project with the Clinton Climate Initiative to replace all 140,000 of the city 's existing streetlights with LED fixtures. In mid-2010, Seattle City Light began installing LED streetlights in a residential neighborhood as part of a plan to install 40,000 LED streetlights over the next 5 years. Also, Atlantic City Electric in Southern NJ is also testing out LED streetlights made by 2 different manufacturers in 4 communities to evaluate if LED lights are worth using over HPS. As of late 2015, Atlantic City Electric has decided to go ahead and replace all utility owned or leased MV and HPS cobra head and floodlights with LED lighting, if the municipality is interested ( which many are ). The town of Stratford, NJ was the first town in their service territory to receive the new LED lights, with many more to follow. The parking lot at Camden County College in Blackwood, NJ is now using LED postlights that replaced the previous HPS flood and shoebox lights. The Cities of Philadelphia and New York have also begun testing LED streetlights and Philadelphia is now in the process of changing existing HPS lampost lights from HPS to LED and all new installs are LED. Philadelphia is also conducting a study to see if it will be feasible to replace all city owned street lights with LED by 2018 ( about 60,000 lights ) and many areas of the city already have them ; other major cities, such as Baltimore and Charlotte, have already begun to replace their HPS lights with new LEDs in different sizes. The town of Abington, PA has installed LED streetlights on their main and secondary streets to replace MV fixtures. In spring of 2011, the municipally - owned energy provider for San Antonio, Texas, CPS Energy, entered into contract with GreenStar LED ( of Boerne, Texas ) for an order of over 25,000 LED street light fixtures. LED street light have been introduced also in smaller cities and communities, for example, in Brisbane, CA. As with other semiconductors, heat buildup in an LED dramatically reduces its life. The temperature at which this reduction in life occurs is often very near summer evening ambient temperatures. Many of the heat - removal technologies used for other semiconductor applications, such as air conditioning systems, fans, or thermal - transfer fluids, are impractical, maintenance - intensive, or cost - prohibitive for street lighting. Airborne dust from industrial and agricultural activities can impair the functioning of finned heat sinks. Achieving good maintenance - free thermal management in an often hostile environment while keeping product cost competitive is the largest hurdle to the widespread adoption of LED street lights. Optical types Non-cutoff The non-cutoff fixtures usually include the globe - shaped lamps that are mounted atop lampposts. These lamps distribute light in all directions. A major problem is created by the light pollution and glare, as they shoot their light upwards into trees and towards the sky rather than towards the ground. Non-cutoff fixtures are rarely found on roadways because they tend to blind the driver. Semicutoff This is the most popular street lighting optic. The semicutoff fixtures usually refer to the cobraheads, but they can also apply to some lamppost - mounted fixtures that do not emit their light upwards. Most of the light can be emitted below 90 degrees, but as much as 5 % of the light can also be emitted above 90 degrees. These fixtures do a good job of spreading the light towards the ground but some uplight is possible, though not as serious as non-cutoff fixtures. Semicutoff fixtures are often mounted on tall poles. Examples of semicutoff optics include the bowl - shaped diffuser on GE 's M400s made prior to 1997, and the prismatic one shared by the Westinghouse OV - 25, Crouse - Hinds L250 and OVM, and Cooper OVD. These fixtures are commonly seen with both mercury vapor and HPS lamps ( and sometimes metal halide as well ). Cutoff These optics give more light control than semicutoffs. Less than 2.5 % of the light can leave the fixture above 90 degrees. Cutoff fixtures have gained popularity in recent years, as they are available from manufacturers like GE and American Electric. The cutoff lights have a wider spread of light than full - cutoffs, and they generate less glare than semicutoffs. The cutoff lenses consist of a shallow curved glass ( also called a sag lens ) that is visible just below the lighting area on the fixture. As with the semicutoffs, these fixtures are very commonly seen with both mercury vapor and HPS lamps ( and occasionally with metal halide as well ). Full - cutoff These lights do not allow any of the light to escape the fixture above 90 degrees. Full - cutoffs distribute their light in a defined pattern, potentially providing more light on the ground at lower power consumption. In recent years, cutoff - type lights have gained popularity. Although full - cutoff fixtures generally use HPS lamps, some metal halide and even a few mercury vapor ones are known to exist, and recent LED fixtures use this optic as well. Semicutoff refractor compatibilities Small fixtures ( 175 watts and under ) Round design : This refractor is shaped like a half - circle, and is usually found on fixtures operating at 150 watts and lower. Examples of round refractors include the ones used by the Thomas & Betts / American Electric Models 13 / 113 / 115 and General Electric M250. Flat design : This refractor uses a prismatic design, and has a flat bottom. It is most commonly found on fixtures operating between 100 and 250 watts. Examples of flat refractors include the ones used by the Thomas & Betts / American Electric Models 13 / 113 / 115, Westinghouse OV - 15, Crouse - Hinds L150 and OVS and Cooper OVX and OVZ. Square design : This refractor is shaped like a square, but some newer incarnations may also have a slightly rounded bottom. Examples of square refractors include the ones used by the General Electric M250, Line - Materials Unistyle 175, McGraw - Edison Unidoor 175 / 250, Crouse - Hinds L150 and OVS and Cooper OVX and OVZ. All three refractor designs are compatible with any small fixture, except the Westinghouse OV - 10, OV - 12 and OV - 14B ( which share the same unique refractor design ). Medium fixtures ( 200 -- 400 watts ) Round design : This refractor is shaped like a half - circle. Usually found on General Electric M400s made prior to 1997 ( and select models from 2008 onward ), they are also used by the remote - ballasted GE Form 400 and Revere 400 - watt models. Line - Materials / McGraw - Edison used a slightly different round refractor design for the Unistyle 400 and Unidoor 400. Prismatic designs : There are many different versions of the prismatic refractor design. A larger version of the flat design is used on the Westinghouse OV - 25, Crouse - Hinds L250 and OVM and Cooper OVD. Another popular design features rounded - off corners, and is compatible with Thomas & Betts / American Electric Models 25, 125 and 325, as well as the 1997 and later editions of the General Electric M400. The Unistyle 400 / Unidoor 400 refractor is also interchangeable with the Model 25, and vice versa. Large fixtures ( up to 1000 watts ) The Westinghouse OV - 50 / Cooper OVL refractor is used by the remote - ballasted Westinghouse OV - 35 and Revere 1000 - watt models, and although there has been very little - known evidence of this, the OV - 50 / OVL refractor is also interchangeable with the Thomas & Betts / American Electric Model 327, and vice versa. The round refractor design as seen on the General Electric M1000 can also be used with the remote - ballasted GE Form 402. Fixture type identification Many streetlights are marked with a NEMA wattage label to aid workers in identifying them. The system is as follows : The color of the sticker indicates the type of light, the number is one tenth of the power in watts. The higher the number, the brighter the light. There are three exceptions to this rule : A `` 17 '' sticker adds a five to the power rating, and therefore, the light is rated at 175 watts. If a sticker reads `` X1, '' it describes a 1000 - watt light. If a sticker reads `` 3, '' it describes a 35 - watt light. Also MH stands for Probe Start Metal Halide, while PSMH stands for Pulse Start Metal halide. Sticker colors : Purple : Incandescent Blue : Mercury vapor White : Light - emitting diode or older HPS Soft White or Colored : Compact fluorescent lamp Red : Metal halide ( Probe start ) Half Red / Half White : Pulse Start Metal Halide ( PSMH ) and some CMH Yellow : Older HPS, LPS, and some induction and some CMH Orange : new sticker color, now used for HPS Colors vary for new LED street lights such as black for Philips Hadco RX1 and RX2 or Green for BetaLED luminaires. The Induction fixtures usually contain a green and white sticker. Some CMH lights also use a yellow sticker as well as red / white. Some LED stickers have the full wattage on them ( Example : it will read 50 LED, which identifies the fixture as a 50 watt LED fixture ) Frequently seen power ratings : `` 3 '' sticker - 35 watts ( HPS / LPS ) `` 4 '' sticker - 40 watts ( Induction ) `` 5 '' sticker - 50 / 55 watts ( MV / HPS / LPS / PSMH / LED ) `` 7 '' sticker - 70 watts ( HPS / PSMH / MH / LED / Induction ) `` 8 '' sticker - 80 watts ( Induction ) `` 9 '' sticker - 90 watts ( LPS ) `` 10 '' sticker - 100 watts ( MV / MH / PSMH / HPS / Induction / LED ) `` 11 '' sticker - 110 watts ( LED ) `` 13 '' sticker - 135 watts ( LPS ) `` 15 '' sticker - 150 watts ( HPS / PSMH / Induction / LED ) `` 17 '' sticker - 175 / 179 watts ( MH / MV / LED ) `` 18 '' sticker - 180 / 189 watts ( LPS / LED ) `` 20 '' sticker - 200 watts ( HPS / PSMH / LED ) `` 25 '' sticker - 250 watts ( MV / PSMH / HPS / Induction / LED ) `` 27 '' sticker - 270 / 274 watts ( LED ) or 100 watts ( HPS ) `` 28 '' sticker - 285 watts ( LED ) `` 31 '' sticker - 310 watts ( HPS ) `` 32 '' sticker - 320 watts ( PSMH ) `` 35 '' sticker - 350 watts ( PSMH ) `` 37 '' sticker - 37 watts ( LED ) - New : For BetaLED 's luminaires in Boston, MA `` 39 '' sticker - 39 watts ( LED ) - New : For BetaLED 's luminaires in Boston, MA `` 40 '' sticker - 400 watts ( MV / PSMH / MH / HPS ) `` 45 '' sticker - 450 watts ( PSMH ) `` 60 '' sticker - 600 watts ( HPS ) `` 70 '' sticker - 700 watts ( MV ) `` 70 '' sticker - 70 watts ( LED ) `` 75 '' sticker - 750 watts ( HPS / MH / PSMH ) `` X1 '' sticker - 1000 watts ( MV / HPS / MH / PSMH ) List of streetlight manufacturers and fixtures This section does not cite any sources.

The original M250 from 1959 to 1960 was actually a fixture with a M - 400 body but with plastic refractor. Additionally, `` Crimefighter '' versions of the M250R exist in Chicago, with a cylinder - shaped refractor attached to the 1970 version 's bodyshell. In 1993, GE Experimented with a slightly re-designed body for the M250R2, but reverted to the current version from 1994 -- Present. ( Example : M2RR25S0A2GMS3358 M250A ( 1967 -- 1985 ) / M250A2 ( 1986 -- present ) ( 50 -- 250 watts ) This PowrDoor luminaire was introduced in 1967 as the smaller companion to the M400A, and its bodyshell was a miniature version of the M400A 's. A full - cutoff version of this luminaire was introduced in 1975 ( Very Rare ! ). It was redesigned in 1986, taking on the M150 's boxy profile, and renamed the M250A2. ARK Lighting 's A601 and A604 luminaires use the same designs as these luminaires, but with notable differences : The A601 ( which is similar to the M250A2 ) uses lamp sizes of up to 250 watts, and the A604 ( which is similar to the original M250A ) uses lamp sizes of up to 400 watts. M400 ( 1959 -- 1970 ) / M400R2 ( 1986 -- 1996 Reintroduced in 2008 -- 2016 ) / M400R3 ( 1997 -- present ) ( 150 -- 400 watts ) Introduced in 1959, this single - door luminaire was discontinued around 1970. From 1970 to 1986, the M - 400 was virtually identical to the M - 400A with the exception of having a non-vented door held in place with a simple spring latch. The ballast components were mounted on the top housing. In 1986, it was revived as the M400R2, with a TuDor-esque flat profile to distinguish it from the M400A2 PowrDoor. The current version ( introduced in 1997 as the M400R3 ) looks similar to a Thomas / Betts 125 except for a slightly bulkier housing and a bail - type latch. M400A ( 1967 -- 1985 ) / M400A2 ( 1986 -- 1996 Reintroduced in 2008 -- 2016 ) / M400A3 ( 1997 -- present ) ( 150 -- 400 watts ) This PowrDoor luminaire was introduced in 1967 as the larger companion to the M250A. Earlier versions had a vented door held in place with a more complex bail latch. A full - cutoff version of this luminaire was introduced in 1975. In 1986, it was renamed the M400A2 ( this incarnation did not have the vented door of the earlier models ), with the arrival of the single - door M400R2. The current version ( introduced in 1997 as the M400A3 ) looks similar to a Thomas / Betts 325 except for a slightly bulkier housing and a bail - type latch. From 2008 until 2016, both the M400A2 and M400A3 were in concurrent production. There are rare 100 watt versions of the M400A3 that exist on the Tobin Bridge in Chelsea, Massachusetts. Additionally, `` Crimefighter '' versions exist in Chicago, with a bucket - shaped refractor attached to the normal 1975 full - cutoff version 's bodyshell.

Helios HBM ( 70 - 400 watts ) The HBM is the medium - sized cobra head of the Helios series, featuring the same features as the HBS. Unlike most medium fixtures however, it will also accommodate all low wattages. Powerlite devices B2217 ( 100 - 250 watts ) The first small Powerlite fixture designed in the 1960s, this design was the smallest of the first generation or Powerlite fixtures, all used mercury vapour lamps however some remain in High Pressure Sodium B2215 ( 400 watts ) The medium - sized fixture in the first generation series, the B2215 could accommodate up to 400 watt mercury vapour lamps. B2213 ( 700 - 1000 watts ) The B2213 was the largest of the first generation and is the largest cobra head style fixture ever made, at more than 4 feet in length. B2227 * Later known as the R37 * ( 50 - 250 watts ) The B2227 was the small fixture in the second generation of Powerlite fixtures, introduced in the late 1970s it was shorter than the B2217. Many B2227s where equipped with High Pressure Sodium which replaced less efficient mercury vapour lamps. B2255 ( 200 - 400 watts ) The B2255 was the medium - sized fixture in the second generation series, it was commonly used with 200 - 400 watt High Pressure Sodium lamps. The B2225 was introduced in the 1970s and was manufactured until the early 1990s. The B2255 was the only fixture that had the option on a power door, where the ballast and other electrical components are mounted on a second door on the fixture, allowing for quick repairs. B2228 ( 1000 watts ) The B2228 used the same housing as the B2255 and featured the same features, however it used a larger reflector inside the fixture to house the larger 1 kW lamps. R47 ( 50 - 400 watts ) The R47 was released in 1992 and would end up being one of Powerlite 's last designs produced until the company 's merger in 2002. The R47 was a small fixture that was about the same size as the B2227 and used the same refractor footprint, it however, was able to accommodate up to 400 watt High Pressure Sodium lamps. R7 ( 50 - 400 watts ) The R7 `` Roadkat '' was the final Powerlite design created in 1996, this fixture feature a more modern slipfitter design and compact size, this fixture still continued to use the same refractor foot print shared by the R47 and R37 ( B2227 ) which is also shared by most small GE, AEL and Cooper Lighting fixtures still made to this day. Twistpak ( 50 - 250 watts ) The Twistpak was a post top fixture manufactured from the 1970s onward, the Twistpak use a modular design, where the ballast and all electrical components where mounted on a tray for quick change out if needed, the top refractor would twist off ( hence the name ) to allow access to the lamp and ballast. There was also a pole integrated version where the ballast was mounted inside the pole and the refractor assembly would mount directly to the top of the pole. The Twistpak design is still manufactured by American Electric Lighting. Revere Revere 400 ( 250 -- 400 watts ) Resembles a Westinghouse OV - 25 Silverliner, but uses an M400 - style refractor.

Ballast and slipfitter is accessed by simply unscrewing a stainless screw on the top and the top `` folds open '' revealing a ballast and slipfitter found on the bottom casing. MO - 9 ( 100 -- 175 watts ) A flat bottomed Silverliner with an external stamped reflector and a ballast casing attached. OV - 12 ( 100 -- 250 watts ) Replaced the OV - 10, predecessor to the OV - 15. Introduced in 1960. This fixture looks like a shrunken - down OV - 50. OV - 14B ( 100 -- 250 watts ) Replaced the OV - 10, predecessor to the OV - 15. Introduced in 1957. It looks like a smaller version of the 1957 design of OV - 25. Also those were mostly used in Canada when the United States had the OV - 12 but the OV - 14B can be found in the USA but is quite rare. OV - 15 ( 50 -- 250 watts ) Replaced the OV - 12 and OV - 14B as the smallest Silverliner. Introduced in 1965 and redesigned in 1979. This was also modified in the early 1970s to use HPS lamps as well as mercury vapor. The Crouse - Hinds L150 was originally designated as an OV - 15. This fixture continues Canadian production as the Cooper OV - 15. OV - 15 TuDor ( 50 -- 250 watts ) Introduced in 1970, this split - door luminaire featured a flatter profile and was designed to compete directly with the General Electric M250A Powr / Door luminaire and was Westinghouse 's first HPS fixture as the regular single door OV - 15 were n't modified for HPS use yet. OV - 25 ( 250 -- 400 watts ) Mid-sized Silverliner, and the most popular streetlight fixture of all - time. Introduced in 1957, redesigned in 1964 and again in 1979. This is believed to be the first - ever integral - ballasted fixture. A remote - ballasted version was also available, with a truncated back as its most notable feature. This was also modified in the early 1970s to use HPS lamps as well was mercury vapor. The Crouse - Hinds L250 was originally designated as an OV - 25. This fixture continues U.S. production as the Cooper OVW, and it also continues Canadian production as the Cooper OV - 25. OV - 25 TuDor ( 250 -- 400 watts ) Introduced in 1970, this split - door luminaire featured a flatter profile and was designed to compete directly with the General Electric M400A Powr / Door luminaire. This was also Westinghouse 's first HPS fixture as the regular single door OV - 25 were n't modified for HPS use yet. OV - 50 ( 700 -- 1000 watts ) The largest Silverliner, introduced in 1963. Adopted fins in the mid-1960s. This was also modified in the early 1970s to use HPS lamps as well was mercury vapor. This fixture continues U.S. production as the Cooper OVL, and it also continues Canadian production as the Cooper OV - 50. Note 1 : Unistyle luminaires are known for their arched top and sloped front end, while their Unidoor successors have a boxy profile. The 175 designation is used for the smaller versions of both styles by most people, but some use the 250 designation, since they were capable of light sizes of up to 250 watts. Note 2 : Silverliner luminaires that have been rebuilt and painted light grey are referred to as `` Greyliners '' / `` Grayliners. '' Usually, they include the single - door OV - 15 and OV - 25 Silverliners, and the OV - 50 was also switched to a Greyliner scheme when Cooper Lighting bought out Westinghouse 's streetlighting division in 1982. Its immediate successor, the Cooper OVL, is also considered to be a Greyliner. Although other Cooper / Crouse - Hinds luminaires, like the OVM / OVS and OVX / OVZ, use the grey color scheme, they are not referred to as Greyliners. Note 3 : It is also very common to reuse older luminaires with newer parts. The most common practice is retrofitting a normal MV luminaire to use HPS lamps. This is being done in most small towns and a few mid-sized cities because it is cheaper to rewire an existing fixture rather than buying completely new ones. Sometimes, normally silver luminaires, like the 1959 - era GE M250s / M400s and Line - Material Unistyles / Unidoors, are repainted light grey ; the most common examples of these are the aforementioned Westinghouse Greyliners. Note 4 : GE 's revival of the M400A2 and M400R2 designs in 2008 is believed to be the first time ever that a manufacturer has resumed production of a previous design. Despite this, the newer 1997 `` American Electric '' designs also continue to be in production. Note 5 : During production of the Westinghouse OV - 25, and to a certain extent, the OV - 15 as well, Westinghouse utilized four different glass refractor designs during the series run. Three of which, used in the first generation ( `` flatbottom '' ), second generation, and third generation ( this style is still used today for Cooper luminaires ), were manufactured by Holophane, the other design, used for the second generation Silverliner, was manufactured by Corning Glass.
