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. 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 animals sleeping patterns. A perfect “night light” bulb for viewing the nocturnal behavior of your animals. European quality for long burn life.
