BlackLights are lights that emit UV rays. There are different types of UV rays. Some are harmful, some are not, and some are necessary for our existence.

    Longwave - UVA (315 to 400 nm), also known as black light, which causes tanning
    Mediumwave - UVB (280 to 315 nm), which causes damage in the form of sunburn
    Shortwave - UVC (100 to 280 nm), which is filtered out by the atmosphere and never reaches us.
