I need some help on this issue. I bought a 8.5" Hot lamp fixture and a Exo-Terra 100w CHE yesterday for Stanley, my new and first tortoise. He's a Leo. Anyways, I set up his enclosure yesterday and set up this lamp to run 24/7 in which it was running fine for several hours until this morning. Before bed last night the temp was about 70 and when I woke this morning it was 57. I don't know if the hot lamp turns it's self off when it gets too hot or if the CHE is just bad. I bought this set up yesterday at the Reptile expo in Pomona so both of these are brand new. Any help would be great.
