Lightroenergy is an amazing new source of illumination which can produce a bright glow for up to a dozen years without any electricity or exposure to sunlight.

Litrospheres are tiny self-luminous particles which can be injection molded or embedded into paints. Brightness is said to be about the same as that of a 20-watt light bulb, but I’d imagine that would depend on how much surface area is covered with the particles. The material is extremely cost-effective, covering an 8.5 x 11 surface for about 35 cents. The particles can even be customized to give off just about any light color. There’s a good description of how the technology works over on PESWiki.

MPK, the company that manufactures this glowing goodness expects Litrospheres to make their first appearance in safety gear, but I’d love to coat all kinds of surfaces with this stuff. Can you imagine how cool it would be to drive down the street in a luminescent car?
