The Exo Terra® Basking Spots are designed to provide a combination of visual light in combination with the correct infrared-A, or NIR heat radiation. Reptiles perceive this as the ideal basking rays for their thermoregulation, since the sun produces most of its energy output in the infrared segment of the spectrum, especially in the near-infrared or infrared-A wavelength. Infrared in general, but especially Infrared-A penetrates the skin very well and will aid cell growth, wound-healing, promote the immune system, protect against UV damage, and stimulate many other biological processes.  The Exo Terra® Basking Spots will allow your reptiles to thermoregulate their body temperature to achieve the optimal temperature for enhanced activity and healthy digestion of their food items. Exo Terra® Basking Spots also emit a small portion of UVA rays, which will contribute to reptiles’ physiological well-being and stimulate breeding behavior.
