CFLs, or compact fluorescent lights, are an environmentally friendly alternative to incandescent light bulbs. Typically a CFL is powered by a ballast which sends current into the glass envelope filled with halogen gas. 'Halogen' is not actually a gas in itself but refers to a family of gasses that includes chlorine, bromine, astatine, fluorine, and iodine. As the electric current travels from the ballast into the envelope, the gas becomes exciting and emits photons. Interestingly, without the the white coating inside a CFL, known as a phosphor coating, you would not be able to see the light produced. It is only once the light passes through the phosphor coating that it becomes a wavelength visible to the human eye.
Fluorescent lights are made from very thin glass lined with phosphors. A very small amount of Mercury is encased in the glass. This type of lighting is very fragile and very economical to use. The lighting turns on and off just like any other light bulb.
CFLs, like all fluorescent lamps, contain mercury as vapor inside the glass tubing. Most CFLs contain 3-5 mg per bulb, with the bulbs labeled "eco-friendly" containing as little as 1 mg.
They are compact fluorescent lights, which are about 5 times more efficient than incandescent lights. For example a 20-watt CFL replaces a 100-watt incandescent.
What does "PAR" mean when associated with light bulbs? Is it the CFL watt equivalent of an incandescant bulb? Thanx, Bob Cushman
my butt cheeks are burning
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
LED lights and CFL lights are a couple
Incandescent: 10-12 lumens per watt CFL: 50 lumens per watt.
Yes, CFL light bulbs can be used in recessed lighting.
The fulform of CFL bulbs is compact fluorecent light
Most recessed lighting will use a CFL as you can now get much smaller CFL bulbs. The Juno Lighting Group ICPL626E (65$) and the Halo H272ICAT (40$) are both designed to use CFL bulbs.
The term CFL bulbs stands for Compact Flourescent Bulbs. You can find general information on sites such as Wikipedia or you can look at CFL's for sale at online stores such as Lightbulbs-direct and LampShopOnline.
The veggies grow best under CFL bulbs indoors are herbs and tomato.
yes and no
CFL stands for Compact Fluorescent Lamp, and they are an energy-efficient alternative to incandescent bulbs. CFL lamps can be used to replace these bulbs, and they can be placed both indoors and outdoors.
No, compact fluorescent light bulbs generally are not autovolt.
No, CFL bulbs are directly replaceable in existing light fittings.
All track lighting models can use CFL bulbs. The important thing is that you get the correct CFL bulb as you must get the CFL bulbs that are designed for base up use like you find in track lights, pendant lights and recessed lighting. If the track lights are dimmable you also want to be sure to get a dimmable CFL bulb.
20/52 times 100/1 = 38.5% rounded to 1 decimal place
Compact fluorescent bulbs used to be all or nothing. They couldn't be dimmed. Most cfl lamps (bulbs) are this kind. However, special cfl bulbs are now being marketed, at a higher price, that can be dimmed by a normal dimmer switch previously used for incandescent bulbs. However, not all dimmer switches work with these newer dimmable cfl lamps.
