Hey, this is Mike. I'm here back with my good friend Matt and we're going to talk about some technology and vehicles that not everybody really discusses too much and that is the lighting. There's different types of technology with headlights and you'll notice with different cars, especially nowadays, that some of them are brighter than others and they some of them have different tents, some of them are wider and some are more yellow-er and some of them have like a blue tint, but we're going to discuss the different technologies and why they're different and maybe even what the future is. So here's Matt, he's going to take us through a little tour here. So if you go down the road and anywhere you can pretty much see a huge merely the different kind of lights from different vehicles anywhere from standard halogen bulbs that run on like halogen gas, there's unangasks, to HID bulbs which you can find in a variety of colors all the way up to LED bulbs which is like the latest technology. Back in 1882 we're going to have like on a model T and everything. The halogen bulb is first created for to provide a light source for vehicles. It's called halogen bulb because of the halogen cycle. The way it works is it's got a chamber like a like a sealed glass sphere and a wire piece of tungsten and tungsten has an incredibly high melting point. So when you run electricity from tungsten the electricity creates electrical friction which starts to emit light and heat and the light rays or what you see is the visible light. That's why it's yellow because it's also heat and it's being released and whatnot. And the reason why it's surrounded by halogen, the reason why it's called halogen is because as electricity is run from tungsten, atoms of tungsten what to mean if they want to like move towards the glass and the halogen actually keeps the tungsten around the filament. There are several advantages that the halogen bulbs, they're very cheap, they're very very plentiful they're used in so many different things but they're also very energy inefficient and they tend to not last quite as long as in on the bulb. Most cars on the road tend to use halogen technology because it's reliable and it's worked for a long time and it's going to continue to work. Another another thing about halogen bulbs is they tend to tend to burn out really quickly. You make them you know they don't tend to last as long as like some of the new aftermarket options that you can find in you know LEDs or HIDs or what have you but there are several other different things you can do as far as like laser lights, laser headlights, you know HIDs and LEDs. So this is the halogen headlight and this is what it produces on this particular car. I do have it on high beams, I put it on low beams so you can see the light there and so Matt is this this this would be the most primitive and probably the dimest light of the the 3. It is light output is measured in lumens or how much light it takes to illuminate a certain like a certain volume. I think it's however much light it takes to illuminate a cubic foot and halogen beams they're really good at illuminating right up front but they lack far off you know and they also tend to be very very random you know some halogens are brighter than others depending on the temperature and depending on the specific amount of current that is on the system you know but it's the most most prevalent kind of lighting available you know because for what it does it you know it provides roughly 800 lumens you know what you're seeing here is probably 800 lumens maybe a thousand lumens you know which is pretty standard out of any call. My friend here has an example of the first kind of aftermarket lights that we have HID bulb HID stands for high intensity discharge it's really fascinating the way they work you can so when when an HID bulb what you have is a small cylinder of gas or gone any inert gas and I don't know if you can see but there's two diodes at each end of the gas chamber and when you run electricity through it electricity will travel through the gas and and calls it to to enter a plasmatic state and release light in the same manner that lightning running through the air causes the air to heat up and release light and depending on the concentration of gas inside the light bulb depends on the color that's because it changes the temperature that it temperature that the gas is inside in its plasmatic state that's why HIDs can you can see HIDs in more than one color like you can cool them down and get like blue and amber cues and heat them up and get you know purple and violet cues you know HIDs have to have a ballast because it takes and it takes a high voltage to run electricity through a gas so when you install a set of HIDs you have to install a ballast that can actually transform the current that's generated from the ballast from the the alternator into a high voltage so it can actually power it HIDs normally they normally come in like a bulb like you can install an HID in any headlight so you notice with an HID the light begins to grow as the gas inside the cylinder begins to heat up it starts to release more light an HID is able to illuminate a much wider path because it's producing light in all directions rather than just directly in front of where that filament is like like a fire you know click a file throw light in all directions and HIDs also able to throw more light down you can see there's a significant amount the significantly more light here this is almost 3,000 lumens of light simply because you know it's more efficient at turning the given amount of electrical energy into light energy not as much electricity is wasted through heat because it doesn't have to heat up metal third kind of after-marking light the third kind of vehicle of the HID which is the most recent the most recent light technology LED stands for light emitting diode which is a fundamental source of light and LED works by having two different membranes inside each one of these little pods and as electrons flow from one membrane to the other they release their energy when electricity flows through these diodes it causes the electrons of the atoms and the electrons to gain energy and as they move from each diode to diode they release their energy in the form of light there are several disadvantages to the LED being that they're very very very expensive and they tend to flicker and they tend to set the bat like the electrical balance of your car they tend to disturb it because they have such a low voltage requirement but they last an incredibly long time you can easily go 50,000 hours on an LED because it doesn't have anything burning it's not sustained it doesn't have a high temperature and they don't they don't really have any parts that can wear out in them both of the different kinds of lights provide more light than a standard halogen bulb but they each have their specific advantages and disadvantages so an LED works in almost the same way it can give you a really close to the same discharge of light the only difference between an LED is it's hard to throw light in specific areas because you know you can't necessarily aim the diode so normally with an LED you'll find like a flood light or a spotlight variant you know which is how you actually aim the light but an LED is able to throw roughly 3,500 lumens equally as well as you know an HID just in a different fashion yeah an LED actually actually uses a significant a significantly less not nearly as much electricity as an HID an LED is the most efficient light source like for the amount of light you get compared to the amount of electricity you consume it's the most efficient
