I got this 4 pack of UV floodlights to add to a lighting setup. They work fine, but they're a little more industrial than I expected and run pretty warm, or at least warmer than I can safely use where I wanted to put them. These are more like floods for stage/ party / rave.
There's a handle for mounting them and they have fins and seems like a metal back, so I think they're supposed to be mounted. Each light has an on/off switch. And they're 390-400 nm so you could probably use them to build a 3D print curing box if you wanted.
