I recently built a basking ledge for my 4 month beardie out of styrofoam which i then grouted and used water based polyurethane to waterproof. I set up his new enclosure yesterday and when i went to check the temp on the basking spot witb my infrared thermometer i got a reading of 144° while the surrounding area still under the heat lamp was omly 112°. Could it be the dark color of the ledge (dark grey) or maybe the polyurethane? I have a 100w bulb would lowering the wattage resolve this ? What other materials can i use that are less heat absorbent?
WOW! 144 is way to hot can you post pics of the ledge and tank and also what uvb do you use what wattage is all your lights for the tank? i would use just wood
