Jonathan had a good diagram of surface coverage because if tort table is thin in length then the temps can also build up, bouncing off the sides, bit like sun trap in the garden. I would say 12 inches would be about ok for your tort but aim for temps rather than height so if sides are retaining heat then perhaps go higher but all sounds ok from what you describe, CB

That's why I think, a halogen bulb and uv strip are better in a small set up.
