Ive got a 75watt infared that i picked up this morning. I am going to hook it up to the thermostat and see what sort of heats im getting, id say they should be around about right, as my enclosure is pretty big. I've also got a piece of slate tile which im going to place on a hide down from the globe close to the bottom of the enclosure that will work as sort of under heating aswell, just making sure it doesnt get too hot. Thanks for the info guys, im beginning with just a switching thermostat, but i can imagine it will go through a few bulbs as you said, so once i save some more funding will get a pulse proportional or maybe just run it without as you do troyster. How high is your enclosure ?
