First off, I just want to say this is an excellent light. I was on the hunt for a very specific combination of both a red LED and a UV LED in the same light, and I believe this was one of only two or maybe the only light out there with those features. It also has type C charging, which is excellent, a magnet which I haven't used yet but it's a nice feature to have, and a clip feature which is super super handy as I wanted the red light feature to be able to use it as a bicycle tail light and the clip makes it much more versatile in that way. In addition to the UV light and the red light it also features a red and blue flashing mode I guess for cops I've never needed that and can't perceive myself using it but no harm in having it and two much more powerful cool white LEDs one that serves on a right angle type light the other one that serves more like a normal flashlight these are both pretty good but this is where my main gripe kind of comes in they appear to me to have very similar beam patterns and I don't know personally I think I can't remember if it was more of a thrower and the other one was more flutty, or if one was a warm white and the other one was a cool white, or just some form of difference between the two, because as it is, they are basically the exact same light, just in a different position, which I feel like could be more versatile. The other small critique I have is I really wish the red light had a blinky mode on it. As it stands, you can either have the red light be constant, have it be breathing, or do the red and blue police mode, as mentioned before. A blinking mode would be ideal for my use case as a bicycle tail light, but I'm still very happy using it on the constant red mode. Overall, great light.
