What is Glow in the Dark?
Glow in the Dark or Photo Luminous Technology is the process of absorbing and releasing light energy. You might have seen it before, on the hands or numbers of certain clocks and watches. In the dark, the hands or numbers give out a green glow, which is clearly visible in the dark for a few minutes and fades out totally within 20 minutes.
New developments in this product have resulted in products that glow for hours resulting in a commercial interest fot this technology.
