A blacklight, also referred to as a UV-A light, Wood's lamp, or simply ultraviolet light, is a lamp that emits long-wave ultraviolet light and not much visible light. One type of lamp has a violet filter material, either on the bulb or in a separate glass filter in the lamp housing, which blocks most visible light and allows through UV, so the lamp has a dim violet glow when operating. Blacklight lamps which have this filter have a lighting industry designation that includes the letters BLB. T
