Lamps heat the air better than almost everything. You have things well in hand I would not worry about it. The fact remains pythons all see heat. Every thing that is warm is a light of sorts. People will speak about CHE RHP not showing light, it is not true, our eyes work differently pythons all have the ability to see heat and track it, so any heat source is a light. It is mostly the keepers that are concerned. The snakes don't seem to be bothered by any lamp red or blue over head, or any over head heater either.
