What type of light does a black light bulb produce?
A black light bulb produces UVA light (as opposed to UVB light). These ultraviolet light frequencies are above violet on the spectrum and are invisible to the human eye.
Are blacklight blue bulbs safe?
UVA, which is closest to the visible light spectrum, is the safest of the three, and this is primarily the type of UV light emitted by a black light. So occasional exposure to a blacklight blue bulb is not expected to cause any health problems.
What is the difference between black light blue and black light?
(The blacklight blue bulb’s light is more purple, or violet.) The light from a black light is much brighter than that from a blacklight blue bulb, because it doesn’t attempt to block all visible light from the bulb. These bulbs are perhaps most famously used in bug lights, or bug zappers.
What is a BLB bulb?
Some consist simply of filters over other light sources that block visible light but permit the passage of ultraviolet wavelength. This type of bulb or filter generally produces light with a dim violet-blue cast, so the lighting industry designates these devices as BLB, which stands for blacklight blue.
