Black Light Bulbs

Blacklight blue (BLB) UVA bulbs produce the type of ‘glow-in-the-dark’ effect that most would associate with ultraviolet light. They’re commonly used in nightclubs or to detect forged bank notes, and also in some UV nail lamps.

BLB bulbs are covered by a very dark blue or purple filter, and give off a purplish glow. Fluorescent tubes – either straight or turned into more compact shapes – are the most common type, but there are other lamp varieties available.
