BLACK LIGHT & BLACK LIGHT BLUE - What's the difference?

Black Lights in general, are fluorescent lights that are designed to emit a specific type (UVA) of ultraviolet light, although a small amount of visible light.

Black Lights are good for making certain substances that would normally be invisible glow (or "fluoresce").

For example, you may have had your hand stamped at an amusement park with an invisible ink that, when viewed under a black light, glowed a bright neon color.

Fluorescent Black Lights are great to use for a party, venue, event or blacklight poster.

Incandescent Black Lights are an inexpensive way to create a party atmosphere.

Black Light Blue lamps are designed with a special deep-blue glass that filters out visible light, producing the maximum amount of ultraviolet light possible.

If you're looking for a black light that produces the minimum amount of visible light for an especially sensitive area, Black Light Blue bulbs are an ideal choice.
