Apparently it glows for 12 years without light or electricity exposure. The way they explain their products sound similar to acrylic paints, 15 minute dry, water clean up, etc.
Litroenergy is a patent pending designed light source material that emits light for 12 plus years- without electricity or sun exposure!
Our development/design of long-life, self-luminous micro particles called Litrospheres (non-toxic) emit light continuously for 12 plus years (half-life point) without any exposure to a light or other energy (not effected by cold or heat). This extremely low cost material offers 24/7 light, which can be injection molded or added to paint. It is 5,000lb crush resistant, stable and constant light source (gives off no U.V. rays). It is designed to give off almost any color of light desired. Our goal is to mass produce this material and supply OEM's.
Litroenergy has potential to save billions of dollars in energy costs world-wide. Litroenergy surpasses all known available lighting options for cost/durability/reliability (12+ years) and safety. The uses are unlimited as the imagination; however we predict the safety aspects to be the front runner in application (light safety tape, lighted life rafts/flotation equipment, light safety markings/equipment, etc.). Supplemental light source will be second as the material is bright and one can read by it, if you have some Litroenergy lighting you will not need to always turn on a light source that requires electricity. The use of Litroenergy in toys, sports/camping equipment, bikes and novelty uses will be close in applications.
The fill rate of Litroenergy micro particles in plastic injection molding material or paint is about 20%. The cost to light up 8 ½ x 11 piece of plastic 1/8" thick is about .35 cents.
I'm not sure I see a place on their website to actually purchase their "litroenergy" products, but they claim it won a NASA award, and not for shuttle pad design either.
