I have an Indian Star Tortoise. He is about 1.5 years old. He weighs approximately 85g. He seems to be happy. He lives in a large Carolina Custom Cage with plenty of places to hide. I have many Exoterra plants and hides for him. His shell is hard and he got a clean bill of health from the vet. My question is the amount of light he should be receiving. I am using a Zoomed 5.0 approximately 24” from the floor of the tank. I purchased a high quality UVB meter. The meter reads about 5.0. I run it on a timer for about 12 hours a day. Is this too much or too little light. I called Zoo Med and really could not get a definitive answer. I looked at the charts they offer, but nothing is clear. Thanks for any input.

You are getting a UVI reading of 5.0 out of a ZooMed Bulb? With a Solarmeter 6.5? What kind of 5.0 and at what distance from the bulb did you get that reading? Is it a HO type bulb?
