I'm usually the guy telling people to turn the heat down but even I think that's too cool. If that was your night temp that would be fine. It gets pretty cool at night in their home range.
Overall you want to be within spitting distance of 80-81 degrees. Personally I think hot spots are a bit silly so I'll either use a wide spreading fixture combined with a CHE or a slightly larger than you'd think you need heat pad and just set it to 80-81 with a thermostat and I'm golden.
