Is there an LED black light?

Is a black light bulb the same as a black light?
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. You may recall the bluish glow coming from these devices.

There are two different kinds of black lights. The rest of what the bulb emits is ultraviolet light in UVA form, which makes fluorescent colors glow but is not seen by the human eye. A true black light emits more visible light than a black light-blue bulb. However, the light emitted is bluer instead of purple.
Are black lights bad for you?

Do LED black lights work as well as fluorescent black lights?
Higher efficiency – UV LED lights are typically 1.5x – 3.0x more efficient than fluorescent UV blacklights. Longer lifetimes – UV LED lights last for 25,000 hours or more, and do not “burn out” like a fluorescent lamp – their UV light output gradually diminishes over time.
