I am having trouble with my UVB light in my box turtles habitat. I have just moved him into a larger terrarium/coffee table house, however, it is quite shallow, and I was wondering if anyone had any ideas for a better way to mount his light fixture. I have a temporary set up right now which is basically a light socket with some tin foil wrapped around the base for direction and shade. I realize this is not an ideal or safe set up and would like to replace it as soon as possible.
