Nitecore Thumb Leo 45 Lumen Clip on Rechargeable Flashlight, UV & Red and Blue

I use this all the time

Ultra violet not very bright. Unlike picture!

I like everything about it but the strength of the UV light. I'm very disappointed by how weak it is, and was expecting more based on the quality of the overall design. The UV light was the primary purpose of the purchase.

This light is easy to attach to almost anything, making it easy to use in many different situations, like the brim of a hat or on a strap with the head tilted. The rechargeable battery is another reason I like this light more than others.

I had the previous version that did not have the UV light or the blue light. I really like the fact that it does have uv light and do not even mind the fact that it reduces the lumens by half. However, I wished that it cycled the UV first so that you weren't blinded by the normal light before getting to the UV. The blue light is okay, but I liked the option in the previous version to have it on solid red. This iteration only has a "siren" blue/red mode. Good for drawing attention, but not as good if you just want to use the red low light. It is slightly larger than the previous version as well. Overall, I really enjoy it and carry it with me everyday. I highly recommend it, but really wish it had the above tweaks
