Heat Producing Lighting is an important aspect to keeping reptiles in captivity. Reptiles are ectothermic (aka cold-blooded), which means they are dependent on their environment for their heating and cooling needs. A basking spot, an area of elevated temperature in your pet’s enclosure, will allow the reptile to raise it’s body temperature, which facilitates digestion and activity levels. There are many different lighting products sold by Josh’s Frogs that will provide both light and heat to your pet reptile or amphibian.
