### energy | radiation | light:

Florescent light
* Most florescent lights are quite greenish, tungsten is very red, and daylight, normal.
* are cool or blue light
  - more green as a rule
  - only effective when they are within a couple inches of the tops of the plants
* can be fine.
* have yet a different color temperature.
* is also very good for starting and rooting cuttings.
* produce light from the Blue light spectrum.
* run on capacitors that pulse current through the bulb at a certain frequency.

Flourescent light
* are a great source of electromagnetic radiation.
* is located in offices.

### energy | radiation | light:

Fluorescent light
* Most fluorescent lights are very green
  - contain mercury
* Some fluorescent lights generate Infrared light in addition to visible light.
* are a boon to the orchid grower
  - available in a range of colors
  - better because it is cooler and consumes less electricity
  - cooler and use less energy
  - four to five times more efficient than incandescent bulbs
  - good to use for a number of reasons
  - high energy lights and can be very damaging to material
  - ideal because they don t produce as much heat, which dries out seedlings
  - more economical than incandescent bulbs
  - now available in bulbs
  - perhaps the best suited light source for cuttings
  - quite different from incandescent lights
  - sort of greenish
* are the most available, efficient and affordable lights to supplement plants
  - worst, giving out large amounts of color-sapping ultraviolet light
  - three to four times more energy-efficient
* can also induce an annoying buzz in audio
  - distort the true color of the foundation
* can severely fade dolls and their features
  - many antiques and their features
* conserve energy.
* consume less energy than incandescent bulbs to give the same amount of light.
* contain very small quantities of mercury.
* create a green bias and tungsten light bulbs create an orange bias.
* die because their electrodes burn out, even though gas and phosphors remain.
* dim in favor of lamps and natural light.
* disperse light evenly without shadows over a wide area.
* gives a more greenish tone.
* is from a linear source which means it is spread out
  - generated as a result of electrical current traveling through a charged gas
  - harsher than incandescent
  - more energy efficient than incandescent light, and the bulbs last longer
  - nearer to natural light than incandescent lights
* is the light of poor people
  - most harmful to beer
  - very unsuitable for colour matching
* makes the image flat, and only gives the eye a few distinct colors to work with.
* perform best when positioned very close to plants.
* provide strong, cool, inexpensive light to plants.
* require a special, much larger and more expensive dimmer.
* save energy and last longer but cast a greenish glow.
* tend to be used more hours per day than incandescent lights
  - very white and harsh on the eyes
  - bring out the blue more, as do overcast skies
* use less electricity and provide more light
  - much less electricity then incandescent lights
* vary according to the amount of phosphorus used by the manufacturer
* work better than incandescent bulbs.

Ghost light
* can be close to ground or in the sky
  * ' are lights in the air that are not well understood by scientists. There are few reports of ghost light sightings. Ghost lights can be close to ground or in the sky. Many ghost lights move

### energy | radiation | light | glow:

Green glow
* can mean heavy metals in the soil.
* indicate that the atmosphere is collapsing.

Headlight
* are automotive products
  - car light
  - located in cars
  - part of electrical systems
* go on when car is moving forward.
* is light
* make weird beating sounds when they're turned on and off.
* require power, and a car's engine produces power using gasoline.
* sometimes shine through objects.
