My beardie is lives in a 48x24x24 Zen Habitat and I have a 34 inch Arcadia 14% T5 HO bulb mounted on the inside of the terrarium (zip tied to the screen top). If she climbs all the way to the top of some of her cage furniture, she is 10-12 inches from the bulb. The minimum recommended distance listed on the site is 15 inches. Would this bulb be sufficient if placed above the mesh?
