Infrared heat is essential for stimulating the digestion of lizards and turtles. The Infrared Plus halogen spots emit infrared heat waves that effectively penetrate the animals' bodies and are perfect for creating "hot spots." The built-in reflector allows the heat radiation to be directed in such a way that a temperature gradient is created in the vivarium, enabling the animals to thermoregulate. Typically, you can observe how the animals move away from or approach the hot spot, depending on the time and their physiological needs.
