Bug Zapper Bulbs are light bulbs that are commonly found in residential and commercial Bug Zappers. A black light bulb (also referred to as a UV-A light with the BL
designation) is a fluorescent bulb that while white when it is turned
off, produces ultraviolet light (called black light) and does not have
the integral UV filter that Black Light Blue (BLB) bulbs have. Black
Light (BL) bulbs do glow purple when in use and are commonly found in
Bug Zappers.
