I got one of these just to mess around with. It is easily the brightest black light I have ever seen -- in my opinion, brighter than the full-size T12 fluorescent tubes. You can easily see objects fluoresce even in daylight.
The previous reviewer is correct, it gets hot quickly without some kind of heat sink. The bottom of the aluminum PCB already has a thermally-conductive pad, so no need for messy thermal paste. I mounted it on a 4" x 6" x 1/4" thick aluminum plate using the 5 screw holes in PCBs. This is enough to maintain a reasonable temperature during prolonged use. It also solves the problem of its crazy shape and provides some sanely-spaced mounting holes at the corners of the plate.
This UV light is very bright. DO NOT LOOK DIRECTLY AT THE LIGHT. I believe looking directly at the light could cause eye injury or damage. Second, the unit gets very hot, consider a way to control the heat such as a heat sink. The unit has an adhesive backing and mounting holes, in my estimation precisely to attach the light to a heat sink. I had one lead un-solder itself within 5 minutes. A very bright UV source!
