Question

what are black light bulbs?

Answer 1

Blacklight is the name of the Ultraviolet (UV) flurescent lights used to make things that reflect color (like white, and other light colors) glow. You cant see the light it self very much because the human eye cant detect UV rays. ONLY flourscent lights have this effect, the incandescent purple bulbs with the microfilaments (most likeley like your bedroom bulb) cant reproduce UV light, it is just purple.

Answer 2

they are the purple lights that make white and neon colors glow in the dark! WOO RETRO!!
