    This is one neat little flashlight. The bright UV LED makes me want to go around the house and see it in a different world. I remember the days when we had Blacklight in our rooms the light up the neat posters that were made. But now I have it in my hand & it is kool.

    Super handy UV flashlight. Almost as good as JETBeam JET-UV Ultraviolet Flashlight (not as far of a throw). But this one costs less.

    Good UV light, but could be better

    This is a handy little tool if you need a UV light. The beam does not project very far, but then again, it will most likely be used for close-up work, such as looking for various bodily fluids (both human and animal), minerals and counterfeit bills, just to name a few. When using this UV light to charge up a GITD device, it works great. Very fast and intense glow. It has the nice fit and finish you would expect from Olight. The threads come well lubricated and are very smooth. The bezel takes a little over three complete turns before it comes off. I would not have minded a fourth turn, just to be safe. I've had other lights of this size and type come loose in my pocket.
