A blacklight (or often black light), also referred to as a UV-A light, Wood’s lamp, or simply ultraviolet light, is a lamp that emits long-wave (UV-A) ultraviolet light and not much visible light. The weak output of black lights, however, is not considered sufficient to cause DNA damage or cellular mutations in the way that direct summer sunlight can, although there are reports that overexposure to the type of UV radiation used for creating artificial suntans on sunbeds can cause DNA damage, photoaging (damage to the skin from prolonged exposure to sunlight), toughening of the skin, suppression of the immune system, cataract formation and skin cancer.

European Black Light, UV-A, UV-B and Actinic Tubes possess different numbering systems to identify them, Philips use one system which seems to be falling into obsolescence, (German) Osram’s system seems to be dominating throughout the world outside North America.

Surface O3 concentrations in Europe may have increased ‘. The phosphor chosen for this type of lamp emits around 370 nm in the UVA. Many flying insects are attracted by UVA radiation, particularly in the region around 350 nm. Elective exposure results from outdoor recreational activity, from intentional exposure to sun-tanning equipment and to sunlight at the beach and elsewhere.
