I am switching my Greek Tortoise off of the compact coil Fluorescent because I have learned it could be harmful to my Greek Tortoises eyes. I have heard alot of people using the Power Sun bulbs which emit UVA/UVB and heat. Also a popular choice seems to be the Repti-sun Tube fluorescent bulbs particularly the 10.0 bulbs. Which do more members use and trust? I just want to ensure my Tortoise has the best enclosure possible. Also currently I use infrared bulbs to supply heat, is it significantly better to use ceramic heat emitters instead?
