The Zoo Med Repti Basking Spot Lamp features a unique patented double reflector that focuses up to 35% more heat and light into a tight beam. Perfect for daytime-active basking reptiles (including various tropical and desert species), it provides beneficial UVA rays which promote breeding and overall mental and physical health. It also increases the ambient air temperature in your terrarium, while creating the proper heat gradients necessary for thermoregulation. Lasts up to 2,000 hours of continuous use.
