Treehugger says: “Litroenergy is a new type of material that emits light for 12 years without needing electricity or sun exposure. The self-luminous micro-particles are called Litrospheres and are said to be non-toxic and inexpensive. The light is said to be equivalent to a 20 watt incandescent bulb. The litrospheres give off a continuous illumination, and can be designed to glow in any color. They can be injection molded or added to paint.” (via New Light Glows For 12 Years : TreeHugger)
