I have my basking light in the smaller metallic looking clamp and the ceramic heater I have in this really big black dome light that says it can withstand 200w of power. I regulated it all yesterday and it didn't eve get too hot on the outside.

My room gets really really cold in the winter and so Im trying to find ways to heat the tanks without the lights. Thats why Im trying to move the ceramic heater closer. But I can use the 40w floodlight for a basking?

Thanks for all your help everyone!
