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.

Glow in the Dark Products gets charged faster with black lights as compared to normal room lights. UV Light Reactive products, Must have a Blacklight in order to work. 

Good to read what Confusious on Wikipedia (https://en.wikipedia.org/wiki/Blacklight) says about the topic first, before Watching this video on YouTube (https://youtu.be/HLH4CqzqFb8).
