Is Ultraviolet Light Safe?

The wavelength used in Streamlight's UV lights, known as long wave ultraviolet light, is completely safe under normal use. In extremely high amounts, however, it can be harmful when exposed directly to the eye or the skin.


This flashlight is warranted to be free of defect for a lifetime of use. Streamlight will repair, replace or refund the purchase price, at its option, of any Streamlight product that does not work or that you manage to break for as long as you own it.
