Hey i am looking for some opinions for this subject. My house is always kept at 75ºF. I use a a 60 watt clear bulb and the temp gets to about 86ºF. But whenever i hold the gecko his underside is always cool ( she doesnt go in the hides on the heated side though). If i got a undertank heater how much would it raise the temp and could i still keep the 60 watt bulb on to warm the air.
