I have tried several different bulbs but none seem to work properly. My Hermann's tortoise is in a 40 gallon breeder. I am trying to set up a warm spot and a cool spot using a basking bulb on one side of the tank. It keeps the warm side in the mid to low 80s and the cool side is room temp at around 75. The basking spot is what I've been having trouble with.
I have tried a regular 75 watt bulb, it got the basking spot to just barely 90 degrees. Then I tried a 100 watt basking bulb (the ones that are shaped for more direct light and better reflection), and it got the basking spot to 110 degrees, and caused the whole warm side of the tank to be around 90 degrees.
Would I have better luck with a regular 100 watt bulb, or a 75 watt basking bulb?
