Strong sources of long-wave ultraviolet light are used in tanning beds.
Although the low-power UV-A emitted by black lights is not a hazard to skin or eyes and can be viewed without protection, powerful ultraviolet sources present dangers and require personal protective equipment such as goggles and gloves.
What happens if you shine a blacklight in your eye?
If you shine a black light on cloth, you will see literally every flaw, uneven color, and even lint. UV light doesn’t make you blind, but it does damage the retina. Most damage is easily repaired, but repeated use could cause serious problems. Eye damage like skin damage is very accelerated.
Is it safe to leave a black light on all night?
Can I keep a black light bulb on all night? (Never leave an incandescent black light unattended—in fact, avoid having them, buy an LED or fluorescent UV bulb instead, they’re much safer, more efficient, and will last much longer.)

Body Fluids Fluoresce Under Black Light
Many body fluids contain fluorescent molecules. Forensic scientists use ultraviolet lights at crime scenes to find blood, urine, or semen.
Do black lights kill mold?
Unfortunately, not all mold spores will be eliminated by surface cleaning. In these cases, ultra-violet (UV) lamps are effective in killing mold and mold spores. UV-C lamps have been used in hospitals for years in order to kill and control germs and mold, according to American Air and Water. Purchase a UV lamp.
