Zoo Med manufactured UVB lights are an essential part of your pets daily requirements. Remember that it not only adds a great visual effect to your setup but it also aids in your animals ability to extract nutrients and calcium from its food. All reptiles are cold blooded and depend on their environment to thermo regulate. This is the reason why reptiles bask in the sunlight to make sure their body temperature is high enough to digest food as well as fight infections and many other regulatory functions. Reptile heating is a must in almost every situation. We carry and recommend Zoo Med products because they are tested to be tried and true. Make sure that you have the right equipment for your reptile pet before you do anything else.
