His whole body needs to be exposed to UVB, outdoors or inside his cage. I don't think I've ever read a discussion on how much cold an iguana can be safely exposed to. IMO one hour at midday at 65F. would be safe. But repeated coolings may make him sick.
The double 10.0's will be fine if they're close enough to his back.
