Tanning Bed Bulb Information
Tanning lamps (or sometimes called tanning bulbs or tanning tubes in some parts of Europe) are the part of a tanning bed, booth or other tanning device which produces ultraviolet light responsible for tanning. While there are literally hundreds of different kinds of tanning lamps, they can usually be classified in two basic groups: low pressure and high pressure. Within the industry, it is common to call high pressure units "bulbs" and low pressure units "lamps", although there are many exceptions and not everyone follows this example. This is likely due to the size of the unit, rather than the type. Both types require an oxygen free environment inside the lamp.
Virtually every tanning lamp or bulb requires a ballast to provide power. While an incandescent lamp, like a typical household light bulb uses a resistor filament to restrict the flow of power inside the lamp, tanning lamps do not. They are plasma devices, like a neon sign, and will flow as much power as you make available to them, even to the point of self destruction.[1] Thus a ballast is needed to regulate the amount of electricity that flows to them.
The primary purpose of the tanning lamp is to create a suntan by other means than exposure to the sun. This is accomplished in a tanning bed, tanning booth, tanning canopy or free standing single bulb tanning unit. The quality of the tan (or how similar it is to a tan from the natural sun) depends upon the spectrum of the light that is generated from the lamps. Most tanning lamps produce much more UV than the sun on a typical day. This gives the user a faster base tan, but one that fades faster and offers less protection from the sun than a natural tan.
