How do fluorescent lights light source works to make the colours?

A fluorescent lamp is a gas-discharge lamp that uses electricity to excite Mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light.
The color a fluorescent lamp puts out is dependent on the type of phosphor it uses. Colored fluorescent lamps usually have a colored tube that together with the color rating produce the required color (red, blue, etc).
Fluorescent lamps are sold by their 'color temperature'. 'Cool White' is 6500K and is somewhat bluish. 3000K is usually labeled 'Kitchen and Bath', which is a bright more natural light. All florescent tubes are labeled as to their color temperature, and some brands also have a scale showing just where it's color is on the spectrum of available colors.

What are cfl lights?
A CFL light is a Compact Fluorescent Light.
Is fluorescent lights fixtures ac or dc?
The basic fluorescent light fixture is AC, although there are fluorescent lights powered by DC.
Type of light that produces little heat?
fluorescent lights
How often do fluorescent lights have to be changed?
Depending on the size of the light and how it is used, a fluorescent light can have a lifespan of anywhere from 8,000 to 30,000 hours. Fluorescent lights tend to lose their brightness over time, so it is recommended to change the light bulb before it burns out completely.
What is a good replacement for overhead fluorescent lights?
The best replacement is a new fluorescent light tube of the right voltage and power.

What is the most unflattering light to do makeup in?

What helps produce light in fluorescent lights?
plasma

Phosphorescence is similar to what other source of light?
fluorescent.
What are lights names?
* Incandescent * Fluorescent * LED (light emitting diode)
What lights are similar to fluorescent lights except that the electron and gas collisions give off visible light?
Neon lights.
What is the deference between incandescent and fluorescent lights?
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
What is a good replacement for overhead fluorescent lights?
The best replacement is a new fluorescent light tube of the right voltage and power.
Which light bulb uses more energy?
Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
