The economical 24-hour heat source for all types of reptiles, amphibians, birds, or small animals. Provides very little visible light so as not to disturb your animal's sleeping patterns. A perfect “night light” bulb for viewing the nocturnal behavior of your animals. European quality for long burn life. Like our Nocturnal Infrared Heat Lamp, the Nightlight Red™ Reptile bulb is also made of true red glass (not painted or coated) for better heat transfer.
