Does anyone know why/which part of those clamp on lighting fixtures is only rated for 100/150 watts? My enclosure I've just built for my Uro is 78"Lx26"Wx34"H. I don't need to heat all of the space but I do need a basking spot that I have a feeling only a 250 watt infra red bulb will produce. I really don't want to ballast a fixture b/c of the way I designed the top. Any help/advice/comments are greatly appreciated.
