I still feel that 80-85 air temp is excessive and can potentially dehydrate the gecko. That said, my living room temps can get into the 90's during the summer and mid 60's in the winter, yet all the geckos are fat and healthy. I find that the geckos initially respond more to the amount of light than to the temp. My geckos eat a lot in August and in mid-Sept, even though it's still warm, they drop off a lot. Some of them eat right through the winter and stay on the warm side. Some move to the cold side and brumate themselves. They don't eat much and don't lose much weight. My geckos are in my living room; I don't have a separate reptile room, and I'm certainly not going to keep my house at 85 for the reptiles. Everyone has done fine for the last 13 years.
