Just thought you guys would like to see this nifty rheostat I came across, it's much cheaper then some of the infrared things from poultry supply places and better fit for small home brooders. I have used these with reptiles before and they work great. I would probably put 2 lights on the brooder, 1 that stays on and one that is hooked up to this and comes on when the temperature drops too low. That would also help in case one bulb blows out.
