Not exactly. So your looking for no hotter then 85 max at basking. I keep mine at 81- 82 not a degree warmer. The hot basking temps is old thinking. They really do not need those extremes and they can shorten their lifespan being kept at such warm basking temps.75w
The actual basking temp is ideal though, right? I thought anything under 95 in the area they occupy is ideal (85-95).
Whether I raise the light more or get a 60w, while that would lower the temp of the actual metal screen it would also lower the basking temp no?
If it were me I would drop back to a 60 watt. Also with the distance you have the basking level sitting at as he matures his casque is going to be that much closer to those dangerous temps where he will definitely get a thermal burn.
