Photo Luminescence
Photo luminescence, better know as glow in the dark, is the emission of light from photo luminescent crystals over an extended period of time. When exposed to light, either infra red, ultra violet or normal house hold lighting, the crystals absorb the light energy and release this energy under low light or dark conditions. The items sold by ERI Products offer the highest “load” of photo luminescent crystals available in the industry today, delivering the strongest photo luminescent glow in the dark capabilities.
