A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.

What is Fluorescent Fabrics?
Fluorescent Fabrics are bright colors like highlight pens. Or for exemple: you know when you have got some work top on the top of your car and it falls off and so that you get noticed you put a bright yellow jacket on so that cars can see you.Well that yellow color is Fluorescent.
What is automatic solar street light?
Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated into the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. Most solar lights turn on and turn off automatically by sensing outdoor light using solar panel voltage. Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not in the sky for an extended period of time.
What Similarity a light switch and a computer?
A light switch and a computer are similar because they both work on the on/off concept.
How do solar yard lights work at night?
Solar lights have a solar panel, control board, photocell sensor, Ni-Cad batteries and a LED (light emitting diode) bulb. The solar panel captures the sun's photonic energy during the day. This electrical current is stored in the Ni-Cad (nickel-cadmium) batteries. The photocell sensor detects available light and the control board regulates flow into the battery. When the photcell sensor detects darkness, the charge stored in the battery is released to power the LED bulb during the evening. Of a morning, the light is switched off to recharge the batteries. Multi crystalline powered solar lights need full sun to charge however amorphous solar panels are still able to charge in overcast conditions.
How does photo detector work?
the energy of light goes to electron movement through electron holes created by raising the energy of the metal in photodetector with the light.
Will a condensed fluorescent bulb work as a grow light for garden?
Only if you buy a "full spectrum" of "grow light" type of compact bulb.
What is a compact fluorescent PI lamp?
PL mean Plug in - Light Bulb, the most comment application is CFL (Compact Fluorescent Lamp) which require assistance components to make it work or light up, different to incandescent light bulb, it can light up by just itself direct connect to our home electricity ac 100v to ac 240v.
How does the compact fluorescent light globe work?
Ask your science teacher lol
Why would a compact fluorescent bulb not work in a standard fixture that's not on a dimmer switch and in which an incandescent bulb does work?
If you have another CFB try it in the same position as the one that is not working. It sounds like the CF bulb is defective.
What is a compact fluorescent lamp and how does it work?
The link shown below to Wikipedia explains pretty well how a compact fluorescent lamp works.
How a light bulb works?
The filament in the bulb (the thin tungsten wire inside) is heated with electricity and then it lights up. That is how incandescent bulbs work. (the old kind) CFL's (Compact Fluorescent Lights) work by a gas (possibly argon) is electrically charged and then the atoms give off light.
Why compact fluorescent bulb doesn't work well in cold weather?
Fluorescent lamps contain a small amount of mercury that must be vaporized to allow current to flow through the lamp and cause it to light up. The colder the lamp, the more mercury is in liquid form and not vapor form, causing a lower light output in the lamp.
Why does a fluorscent light not work in the cold?
fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.
Full form of PL Lamp?
PL is mean Plug in - Light Bulb, the most comment application is CFL (Compact Fluorescent Lamp) which require assistance components to make it work or light it up, different to incandescent light bulb, it can light up by just itself direct connect to our home electricity ac 100v to ac 240v.
What effects do compact fluorescent bulbs have on computers?
None or a negligible effect. Similarly to incandescent or fluorescent tubes, they light up your work area so you can see what you're doing at the computer.
Fluorescent HID lights best accompany what soil type?
Fluorescent HID lights work well with all types of soil, instead try matching the type of fluorescent light with the type of plant you're growing. Standard fluorescent give of duller light and work better with starting a plant that will eventually go outside. Compact fluorescent, on the other hand, give of much more light and work best with growing larger plants indoors.
How do CFLs work?
A compact fluorescent lamp rather than producing light by creating heat (i.e. like an incandescent light source), produces light by exciting mercury vapor inside the bulb's glass envelope. The initial excitation of gas is not enough to produce visible light (at this point it is actually UV light), the light produced is only visible once it passes through the phosphor coating on the inside of the bulb.
