So my enclosure for my baby beardie (who I do not yet have) is a 30" x 12" x 18" high 30 gallon tank. It's got the same dimensions of a 20L except it's 6" taller.
I recently received the 100 watt Repti Basking Spot Lamp I ordered, and tested it out in my enclosure. I was using my RetiTemp infrared thermometer to check temperatures, using the MAX setting so it would show me the highest temp I scanned. Here was my results for the temperature of the basking spot:
Just Turned on - 83.0°F max
After 5 minutes - 91.5°F max
After 10 minutes- 97.5°F max
After 20 minutes- 106.5°F max
After 40 minutes- 110.0°F max
So my basking spot got to a high enough temperature, but when I checked the farthest part of my cool side, the temp was somewhere around the high 70s, creeping into the 80s and then the 90s the closer I got to the hot side.
Is that a high enough temperature for my cool side, and if not, what should I do about it?
My battery on my cool side died for my thermometer. In the winter it was about 75 at the lowest corner farthest away from the basking spot. With mine I figured if he wanted to be colder he would go to the corner or in his hide and move positions to adjust (hotside, coolside up or down) how warm he wants to be.
