ZILLA Incandescent Day White Light Bulb 100W

The bulb simulates the natural daytime photo-environment of a desert or tropical habitat while providing a heat source needed for a healthy reptile environment. Photons from the daylight bulb pass through the glass heating the opposing surface allowing the reptile to bask in its warmth. The bulb is made from glass containing rare earth neodymium phosphors to produce a brighter, whiter light.
