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...

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...
