I used a metal L bracket that is for shelving. I then attached my heatlamp with some S hooks that are tightened and it hangs down from the bracket about 1 1/2-2feet above my water dish. I wrapped the cord numerous times around the bracket and then also it's secured in 2 other spots along the wall so if 1 fails, it will still be safel!
My geese would mess with the lightbulb, they would unscrew it, so I had to build a wire mesh around the heat lamp to keep them from getting to the light!
If you just make sure when you put yours in, however you decide to set it up, make sure if 1 attachment gets broke that you have numerous others to keep it from getting close to anything that could burn!
