It depends on which cage it is. My two rhp that I run year round are in my tall arboreal cages for my ETB and GTP and I use the rhp only to create a hotspot on the perches just below the panel. Both of those are set to 89F which gives me a hot perch of 86. Each perch is about six inches below the panel. At this temp the center of the panel is usual 100 or a bit over which drops as you get close to the panel edges.
So on the edge of the panel it is 89 with a hot center at 100 to give me a hotspot six inches away of 86F. Using them for this I don't have to run them hard since the target I want warmed is so close.
My other panels are not on right now as it is warm out and I don't need them. I only use them on cold nights for a little extra heat. So again I don't run them hard as my cages have them and uth with the room being heated as well.
