Whats the difference between a blacklight and a blacklight-blue bulb?
Blacklights are fluorescent lights that are designed to emit a specific type (UVA) of ultraviolet light (although a small amount of visible light is emitted as well). Blacklights 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 blacklight, glowed a bright neon color. Blacklights are available in Fluorescent and Incandescent. Fluorescent Blacklights are great to use for a party or blacklight poster; Incandescent Blacklights are an inexpensive way to create a party atmosphere.
