These lights use USB-C to recharge, and include some side LED's (white, UV, red, red flashing and red/blue flashing modes). The side modes are a lesser used so it's cool that there is a separate (right side) button to control them, while the main LED's have just four modes from high to dim (controlled by the left button). For some reason the manual claims there are 5 modes on the main LEDs, but there are only 4 (which is plenty). The UV LED is modest but it does work. It may struggle to find scorpions with it from more than a half dozen feet, but will work to check out UV security features or printing. The butt end has a neodymium magnet which tends to grab anything within reach and glom onto other items on a keychain, but is a nice feature. I have not tested the water resistance, which they claim is IP65, so I'd not plan to dunk it. The USB port has a rubber cover but I don't know how well it would hold out water. It should be fine in the rain though.
Since buying the first couple lights, I have received a few more which are destined as gifts, and while testing them I noted that (on high) the black version is a bit dimmer than the glow in the dark (GITD) / clear version. This was consistent across several I tested. But what was a bit concerning is that the clear version (which seems to be brighter on high) also gets hot after running on high for about 5 minutes. I never really noted an issue with the black version getting hot while running on high, so I suspect that the GITD/clear versions, which I received may run the LED's at a bit higher current for some reason. It is almost like the GITD/clear version starts up in a turbo mode compared to the black version. Unfortunately the 2nd brightest mode on the GITD/clear version is probably 25% less bright than the high mode on the black version (but it stays cool). Therefore stepping down a notch on the GITD/clear version will not really equal the normal high mode on the black version - but the 2nd brightest mode on the GITD/clear version is plenty usable. So in a nutshell, if you tend to use a light on high for more than 5 minutes at a time, then the black version is probably a safer bet. If you want the brightest light but don't mind stepping down to the 2nd brightest mode for normal use, and like the fact the light will glow in the dark, the GITD/clear version would be a better pick.
Runtime is good with at least 80 minutes for the black version on high (and it did not get hot), and the same time for the GITD/clear version on the 2nd highest setting, which also remained cool (they could have run longer but I shut them both off at 80 minutes).
I think both lights have their use, but the one I keep in my pocket is the black version. I wish it were glow in the dark but that is honestly not something I would use much anyway. I prefer to just turn on the light and use it without worrying about the light heating up. Being mostly plastic, I doubt the LEDs will have much in the way of heatsinking, so if using the GITD/clear light, it makes sense to stick to the 2nd highest mode normally and only use the highest mode occasionally. Below are some pics of the lights including one beam shot of the high modes of the black (left) and GITD/clear lights (right) and one of the GITD/clear light after being charged up with a flashlight for a few seconds so it would glow (I adjusted the image to appear close to how it actually appeared). Pardon the pocket lint.
If you pick one of these up for Christmas gifts, it would be good to order soon if buying from AliExpress (since it can take several weeks to deliver). Amazon also sells them but expect to pay more (but you will of course get it sooner).
I have some more lights from AliExpress, which I have received in the past couple days and will post reviews for them as well.
