How to shoot under fluorescent lights.Presents instructions on how to take pictures under fluorescent lights. Effect of fluorescent lighting on picture colors; Use of color compensating FL-D filters over lens; Do-it-yourself filters from plastic color-compensating (CC) filters; Use of camera flash...
So, if you are still using fluorescent lights in a commercial or industrial facility, a lighting upgrade to LED lights can cut your energy costs by half. A very common upgrade we help with all the time is converting fluorescent T5 high-output high bays over tolinear panel high bays. At t...
Overall, a typical fluorescent lamp is four to six times more efficient than an incandescent lamp. People generally use incandescent lights in the home, however, since they emit a "warmer" light -- a light with more red and less blue. As we've seen, the entire fluorescent lamp system ...
Afluorescent lightworks on a similar idea but it has an extra step. Inside afluorescent lightis low-pressure mercury vapor. When ionized, mercury vapor emits ultraviolet light.Human eyesare not sensitive to ultraviolet light (although human skin is -- seeHow Sunburns and Sun Tans Work!). Ther...
To grow healthy plants, you need to give them the right quality and quantity of light. Commercial grow lights are specially made to provide the right wavelengths of light, but you can get the same results using a mixture of cool-spectrum and warm-spectrum fluorescent tubes. Getting enough lig...
There are several different articles having to do with light here at HowStuffWorks: Halogen lights Gas camping lanterns(the kind with mantles) Lasers Fluorescent lights Electroluminescent panels All of these technologies excite atoms so that they produce photons. In the case of halogen bulbs and gas...
How Fluorescent Lights Work Fluorescent tubes work on a similar but different principle from incandescents. In the latter, the filament is electrified and provides high resistance to the current, which causes the filament to glow inside a confined glass globe. This creates light, but also a lot...
Compact fluorescent lamps, or CFLs for short, contain argon and mercury vapor housed within a spiral-shaped tube. They also have an integrated ballast, which produces an electric current to pass through the vaporous mixture, exciting the gas molecules. In older CFLs, it took several seconds for...
A light bulb, for example, has a filament inside that is very resistant to flowing charge. The charge has to work hard to move along, which heats up the filament, causing it to glow. In building wiring, the hot wire and the neutral wire never touch directly. The charge running through...
Never wire a regular dimmer to an older fluorescent light fixture that is not rated for dimming or a fixture which has CFL - Compact Fluorescent Lamp adapters. Dimming non-compatible fixtures or lamps will cause the fluorescent lamps to over heat and burn out prematurely. ...
