I was told a few times by some people that I should probably return my CHE bulb and get a 65 watt incandescent bulb for heat (since I already have UVB for my collared lizards). My question is, would a 65 watt incandescent bulb make a hotspot of 100-110 degrees? I'll have it hooked up to a thermostat (not sure if I need to hook up my UVB up to a thermostat though). Does anyone have any experience in this? I also have a 40 gallon long breeder tank for two babies, would I need more than one hotspot?
