Its a 25watt one at the moment and about 5-6 inches away for the "basking spot" , shining through the glass sliding door. If I put my hand on the basking spot I can feel modrate heat on the back of my hand but not too hot. She has not basked in it yet and just seems to crawl up the glass to try and use it like a heat matt . I will give it a fair tiral for a few days and if shes still a little apprehensive I will revert back to the heat matt.

The 25watt seems to make it hot enough from the distance I have it at.

Any suggestions?
