The UV light is not emitted from the front but from a much smaller emitter on the side. You have to switch over to this The UV light is not particularly powerful, i.e. not particularly bright, and can only be used as an auxiliary function.

Hello Antonio Unfortunately I can't help you with these technical details. But I am very satisfied with the lamp. Top quality, waterproof and shockproof, easy to charge, graduated brightness, adjustable light beam, lots of accessories. I can only recommend the torch.
