Not really. Tegus are VERY DIFFERENT than most reptiles, in that if they want to hibernate, they are going to hibernate--regardless of temperature or light manipulation. I've had MVB lighting at 100 degrees and had tegus hibernate. In my experience, in a tegu's first year, you CAN have some success and preventing or shortening hibernation, but there are no guarantees. Tegus that have been hibernated in the past seem more apt to continue that practice.
