Quite a few of us hang the light instead of using the clamp feature. If you can't put a hook in the ceiling and a chain for the light to hang from, then maybe you can fashion some sort of stand to hand the light on. This is much safer than using the clamp. And just to reassure you, this has happened to a lot of us. I opened the lid to an outdoor hospital pen one day in the winter and smoke billowed out. The clamp had failed and the light went down onto the cypress mulch substrate. If there had been more oxygen in there it would have burst into flames, but the bell of the light was effectively closing out the air.
