A<unk>  is a device that emits ultraviolet radiation, usually for the purpose of a cosmetic tan.  They are very similar to a<unk>  bed, but the design is such that it is intended to be used while standing up, rather than lying down.  Many persons prefer using a<unk>  rather than a<unk>  bed (or sunbed) for several reasons, but the main reason given is sanitation. This is because the user is always standing up in a<unk> , so there is little contact with the actual unit, unlike a traditional<unk>  bed.  While there are many stories of people catching diseases from<unk>  beds due to prior users (herpes, etc.) this is more myth than fact.<unk>  beds are usually cleaned using an FDA approved disinfectant which is very inexpensive, and the UV itself controls bacterial growth, and is a very effective sterilizing agent.  Assuming the operator follows simple cleaning instructions, the risk is very minimal for either type of system.<unk> s generally use 160 watt VHO (Very High Output) or VHO-R (Very High Output with Reflector) lamps, but some less expensive systems use standard 100 watt HO (High Output) or RUVA (Reflector UVA) lamps.  Many people confuse "VHO-R" and "VHR ", with the latter being a trademark of Cosmedico lamps for their versions of the VHO-R lamps.  The average<unk>  has from 32 to 56 lamps and uses a 10 to 15 minute<unk>  session time.
