A tanning be or sunbed is a device emitting ultraviolet radiation (typically 95% UVA and 5% UVB, +/-3%) used to produce a cosmetic tan. Regular tanning beds use several fluorescent lamps that have phosphor blends designed to emit UV in a spectrum that is somewhat similar to the sun. Smaller home tanning beds usually have 12 to 28 100 watt lamps while systems found in salons can run from 24 to 60 lamps each consuming 100 to 200 watts.
