Heat your night active animals and be able to observe their night time activity. A reptile Black Moon spotlamp will provide heat, with very low light levels. The lamp is designed to provide a general warm area and is not a concentrated spot light. The lamp Wattage should be chosen to match the appropriately rated holder, the size of cage, type of animal being heated and the temperature required. A Dimming HabiStat thermostat should always be used to control the temperature.
