What is a Black Light Blue Bulb?
A black light blue bulb is a special bulb that emits blue light which filters out the white light in the room making the ultraviolet light in the room become visible. (See ref. 1) The black light blue bulbs produce a glow in the dark lighting effect due to the glowing ultraviolet rays.
How does a Black Light Blue Bulb Work?
Black light blue bulbs have a deep blue purple color glass which blocks visible light and look like regular black bulbs when not in used. They are able to produce the utmost quantity of UV light due to their blocking out all white light. Black light blue bulbs emits a deep, soft purplish light which is not black light but simply a left over visible light produced by the bulb. (See ref. 2)
A black light will make anything containing phosphors seem to glow in the dark. Phosphors are substances that will produce a visible light when exposed to energy. The ultra-violet light emitted by a black light finds these phosphors, and turns them into visible light.
Most black light bulbs are made with a dark glass to block off most of the visible light given off by the bulb, so that only the ultra-violet rays are emitted. (See Ref. 3) Once the ultra violet rays leave the bulb, it finds phosphors in the room and the result of the reaction of the emitted energy with the phosphor is illuminating light.
What is the difference between Black light and Black Light Blue?
Black lights and black blue light both emit an ultraviolet light that makes invisible or fluorescent substances glow or appear in the room. Whereas black light bulbs emit a black light and some visible light, black light blue bulbs emit a dark blue light and no visible light in the room. Thereupon, the black light blue bulbs are better at blocking and filtering out most of the visible light in the room than black light bulbs. (See Ref. 1).
