My 10 color LED flashlight doesn't have UV but I carry a UV Photon on a key ring attached to the same light. It won't throw much light but it's handy for things like that. It will also light up some spiders and scorpions which could be handy before you go poking and proding in some matted grass 6 inches from your face.

I should also note that I'm Red/Green color blind so the application of color likely won't work the same for me as it does a person with normal vision. This is something I'm still trying to figure out and why I got a light with so many colors...what works for me might differ from accepted standards.
