Our Aqua Culture 60 Watts Basking Bulb provides the radiant heat (infrared light) that reptiles need to thrive. Reptiles are ectothermic and depend on their environmental temperature to regulate their core body temperature. Our bulbs concentrate heat and light for basking reptiles so they can achieve the necessary temperature to be happy and healthy. When picking a bulb, simply refer to the easy-to-read reference table to simplify selection based on the distance the bulb will be placed from the reptile. Check out other products from Aqua Culture like aquarium hoods, tank ornaments, gravel, lights, and more for all your aquarium needs. Your reptilian friend will love basking under our Aqua Culture 60 Watts Basking Bulb.
