I have my heat lamp suspended with a heavy duty chain. I wanted to make double sure it wasn't going anywhere. I can adjust the height with an S hook in the chain. Yes, I heard about nasty fires with these lamps. I wanted to be extra cautious. Hope you are able to get things back to normal. Glad no one was hurt!
I have a 250 watt heat lamp with a clamp from TSC. It somehow fell into the wood chips and lit my house on fire.
This happened about an hour ago. The heat lamp had no trouble for the first six hours of use so...
Pro-tip = Make sure the clamp works well where you set it. I can only assume that something wasn't put on correctly.
