Unlike incandescent bulbs which use a filament compact fluorescent light bulbs give off light when a mixture of three phosphors are exposed to ultraviolet light from mercury atoms.
What is an compact fluorescent light bulb.
After i bought a few compact fluorescent light cfl bulbs i heard they contain mercury.
Compact fluorescent lamps cfls are designed to mimic the light produced by incandescent lamps and are roughly the same size.
Cfl bulbs are another type of energy efficient bulb much like the led.
Modern cfls typically last at least six times as long and use at most a quarter of the power of an equivalent incandescent bulb.
Some types fit into light fixtures designed for incandescent bulbs.
Cfls are known as compact uorescent lights or compact uorescent light bulbs.
How dangerous are these bulbs.
Manufacturers had already started producing linear fluorescents but the linear tubes did not fit into the same socket as incandescent light bulbs.
What if one breaks.
In a cfl an electric current is driven through a glass tube containing argon and a small amount of mercury vapor.
They last 10 times longer and utilize about 1 3 of the energy of typical incandescent bulbs.
This generates invisible ultraviolet light that excites a fl uorescent coating called phosphor on the inside of the tube which then emits visible light.
There are two major types of compact fluorescent lamp screw in and plug in.
The compact fluorescent light bulb or lamp is a type of fluorescent lamp generally designed as a replacement for incandescent or halogen lamps.
A compact fluorescent lamp cfl also called compact fluorescent light energy saving light and compact fluorescent tube is a fluorescent lamp designed to replace an incandescent light bulb.
How much can i save if i use compact fluorescent light bulbs.
They cost much more at the outset than traditional bulbs but are estimated to save about 30 u s.
Dollars in electricity costs over the life of the bulb.
They use only a fifth of the electricity in other words they are 400 more efficient.
Around the world governments have passed measures to phase out incandescent light bulbs in favor of the more energy efficient cfls.
Cfl bulbs or compact fluorescent light bulbs are very similar to the overhead fluorescent tubes you re used to seeing overhead in many commercial spaces.
Cfl stands for compact fluorescent light bulbs.
How do compact fluorescent light bulbs work.
A compact fluorescent light bulb cfl is a fluorescent light bulb that has been compressed into the size of a standard issue incandescent light bulb.
