I bought one a while back, the driver went all wonky and BangGood sent me another driver (ordered from Banggood, not fasttech, same light though)… Somewhere along the way I fried the emitter…. Sometimes the learning curve is a pain…
The UV was good, looked to be about 365-370nm… I got the three mode like listed, it is actually usable modes. Worth it for just the host, which I turned into a triple now.
