Black lights come in both tube and bulb form. The conventional black light design is just a fluorescent lamp with a couple of important modifications. Fluorescent lamps generate light by passing electricity through a tube filled with inert gas and a small amount of mercury. (See How Fluorescent...
Buy a CFL Globe to replace the globe lights in your bathroom. Don't put 40-watt equivalent swirls in a wall sconce that takes candle tip or candelabra bulb; they'll look silly and you (or someone else who lives in the house) won't be happy with them. Also, make sure you like the...
Fluorescence and phosphorescence: The emission of light in response to radiation energy (as in a fluorescent light bulb or a television) Laser generation: The concentrated emission of light using stimulated emission All these processes work on the same basic principle — an outside source of energy...
Fluorescents are delicate when it comes to their functionality and composition. These lights only perform well in a room-temperature setting. In fact, in temperatures under 50 degrees, you can expect the light to perform at max, at 80% capacity. Plus, this is only when you put up a brand...
This arc lights the bulb in the same way a larger arc lights a fluorescent bulb. One of the electrodes is a bimetallic strip that bends when it is heated. The small amount of heat from the lit bulb bends the bimetallic strip so it makes contact with the other electrode. With the two ...

In fact, a typical light bulb produces perhaps 15 lumens per watt of input power compared to a fluorescent bulb, which produces between 50 and 100 lumens per watt. Combustion offers another way to produce photons. Combustion occurs when a substance -- the fuel -- combines rapidly with oxygen...
Light bulb(s) - Fluorescent light that attracts insects, usually mercury, neon or ultraviolet (black light) Wire grids or screens - Wire meshes (usually two) that surround the light bulb and are electrified to kill insects Transformer - Device that electrifies the wire mesh, changing the 120-...
