If you do heat one side of the cage from a distance, my experience ( just terrestrial Ts) has been that they will bask in the heat on the wall. And while it is nice to see them, I think it is a bit unnatural. I have switched from heating pads on a pane of glass to heating cable looped around my enclosure containing my acrylic T enclosures. I looped it such that it is low in some places and higher in others. They seem less likely to bask since I did this, except for my G. pulchripes who is in pre molt. She spends less time basking, but more than the others.
