Below this is the "ultra" violet region which the human eye cannot see. Note that visible light can start at 395nm+ which is the "violet" region - the first region in the rainbow. This is filtered ultraviolet light emitted at 365nm (nanometer) wavelength. If you are looking for an excellent 365nm UV light then definitely look at the uvBeast V3 365 it’s well worth the money.” Don’t expect to have a bright blue light like you see with the 395nm lights, it’s just not there and almost looks dim until you hit something that does react to the UV and then it’s ”WOW” time. There is a lens on the light that also blocks any stray non UV light so you are really getting as much 365nm UV output as you can get. I went around the house initially couldn’t believe all the stuff on the carpet that the 395nm lights don’t even show. Nothing I currently own even comes close to putting out this much true 365nm UV. As far as UV output, I was completely floored by how much 365nm UV this puts out, just amazing and it blows all my current lights completely out of the water. I already have plenty of the 18650s around and decided to add the extension to extend the battery life while testing this bad boy out.

It was really nice that they include batteries and the charger. It came with two 18650 batteries, charger, and extension for adding a third battery if you wish and the light itself. The V3 is a very heavy duty light, built like a tank that could take a lot of punishment.

I already have their uvMini version and was extremely impressed by the output of the 365nm vs my other 395nm lights. “I saw that uvBeast was coming out with a new V3 in 365nm and had to give it a try.
