Reptile parents, this deep dome lamp fixture is a must-have for setting up your pet's basking spot or providing necessary heat and light. The 5.5-inch deep design is perfect for focusing the light and heat downward into the enclosure, and the polished reflective interior helps maximize the effect so less energy is wasted. You can use it with a variety of bulbs: basking bulbs, ceramic heat emitters (for heat without light), UVB bulbs, night heat lamps, you name it. It has a ceramic socket (not plastic) that can handle high temperatures without melting. There are vents on top to let heat escape so the fixture itself doesn't overheat. It comes with a decent 1.7-meter (about 5.6 feet) power cord and, best of all, a built-in ON/OFF switch right on the cord so you don't have to constantly unplug it. It also has a handy hook for hanging it above your terrarium. Just make sure you're using the correct wattage bulb for your fixture and your pet's needs. A reliable, basic piece of equipment for your bearded dragon, snake, gecko, hermit crab, or other reptile/amphibian.
