I think the reptile lights are a way for the pet shops to make money also.
The male we have been breeding with,we have had from a few months of age and is now 9 years old and has never seen a reptile light. They need to have access to sunlight and an area to dry out so a platform in the sun will do both. I heat mine to about 25 deg C. and they do not hibernete. If they hibernate they need to get to very good condition first. They do not have to hibernate, and I am expecting mine to start breeding again soon. It is all a matter of personal preference, just make sure that what you choose is good for the turtles.
