I just built Zeus(zeusy blue bars I call him when talking to him)a 5x2x2 enclosure. 100⁰-105⁰ basking. 90⁰ ambient hot side down to 82⁰-75⁰ or so on the cool side. Tile floor. Logs rocks and varying granite for him to climb around and shelter too if he chooses.. Right now he has a 36" zoo-med T5 H.O. hood with a 10.0 34" bulb(I believe the 34" bulb is 39watt). I just ordered 2 arcadia 14% dragon lamps because this enclosure is much larger than his 40 gallon breaker he was raised in. He is just under a year old. I'd love to post a pic or 2 but don't know how. Just curious on your thoughts as I have heard the Dragon lamp 14% do great on top of larger enclosures. About 16"-20" away from basking spot I'd say.
