Litrospheres are self-luminous microparticles that the manufacturer, MPK Co., swears are inexpensive, non-toxic, and will stay on for 12 or more years continuously without needing electricity, solar power, or any other power source.
The Litrospheresâ„¢ are not effected by heat or cold, and are 5,000-pound crush resistant. They can be injection molded or added to paint. The fill rate of Litroenergy micro particles in plastic injection molding material or paint is about 20%. The constant light gives off no U.V. rays, and can be designed to emit almost any color of light desired.
And the best part of it is: glowing, vibrating panties!
