I've read through many care sheets that say light fixtures and heat mats are both okay to use. However, I've found that ANY light I've tried has made the temperature rise to extremes. I have a thermometer on the substrate and a thermometer on the inside glass near the bottom of the tank. It's my understanding that the substrate temp is what is the most important and even a 40W bulb quickly brings it up to dangerous temps. I have a zoo med heat mat and thermostat quickly on it's way overnight to get this regulated (I use one on a rosy boa tank and it keeps the temperature of the substrate perfect regardless of the room temps). I decided that since I already had a light fixture that I would put a UV light in it but it also made the temp in the substrate rise quickly (over 100 degrees). Sorry for the long post, but am I doing something wrong here? I'm feeling frustrated that anyone would use a light fixture after seeing these temps. Something can't be right. He's an adult gecko, 10 gallon tank - moving to a 20 gallon tomorrow. I'd appreciate any comments! Thanks!
