The Exo Terra Glow Light offers you the opportunity to place heat and/or light sources in your terrarium where they are needed. The device is robustly constructed, featuring a metal reflector, a heat-resistant ceramic socket, and a spring-loaded swivel clamp. It can be easily turned on and off with the switch on the extra-long power cord. The inside of the reflector is coated with a highly reflective luminescent layer that continues to glow long after the lamp is turned off. This allows diurnal reptiles and amphibians to retreat to their nighttime burrows or hiding spots without stress. A moon-like glow enables nocturnal reptiles and amphibians to see well without disturbing their night cycle. It is also ideal for observing your animals at night without turning on the light, which can cause stress and disorientation.
