Lunateks™ are high performance phosphorescent panels.
Lunateks™ charge in bright light in a few minutes, then glow for hours, with their output tapering off, but providing a cool, green, dependable light. Not just enough to see, enough to see with. Light emitted depends on brightness of excitation light, and tapers off fast at first, then gradually. As your eyes dark adapt, you can continue to see. This is called an "exponential decay" process, and will be explained in a new post soon.
Lunateks should not be confused with old fashioned, "glow-in-the-dark" products that fade in minutes, or costly lightsticks that you se once, and throw away. Place on a nightstand for a gentle, dependable nightlight. Great for finding your way in dark, hotel rooms at night. Leave a Lunatek™ in your child's bedroom to comfort them as they ease off to sleep.
Lunateks™ glow for 10 full hours (with tapering off light!), and can be recharged thousands of times.
Lunateks™ are completely safe, totally non-radioactive, and extremely durable. Resistant to UV and moisture, but should be stored away from sunlight and water for maximum life.
Keep a business card size Lunatek™ in your wallet and you'll never be without a portable light in an emergency.
Lunateks™ – Useful light that lasts all night™
Lunatek™ phosphorescent lights use a very large amount of high performance, strontium aluminate type phosphorescent powder, as much as 33% by weight in a 1.5 mm thick panel, to emit as much light as is practical from a sheet of material. They are vastly brighter, and glow much longer, than traditional zinc sulfide phosphors, and are brighter than other strontium aluminate phosphor based paints, decorative articles, and exit signs.
Lunatek Patent Info
United States Patent Patent No.: 7,153,539 Date of Patent: Dec. 26, 2006
High Brightness Phosphorescent Panel
Inventor: Mark C. Waterbury
Assignee: Cleveland C. Smith
This invention describes an article of manufacture that comprises an optimized phosphorescent laminate structure that produces much brighter light than previously disclosed phosphorescent laminates or coatings by enabling and capturing multiple emissions and reflections of light emitted by phosphorescent particles that are distributed through the thickness of a transparent layer. These multiple emissions are enabled by providing a transparent carrier layer that is many times as thick as the phosphorescent powder particle size. That layer is loaded with an amount of phosphorescent powder that is low enough to allow light emitted by the deeper layers of powder to escape, but high enough to provide a very large amount of emitting powder. This structure may be protected by surface films and backed by a reflective layer for efficient unidirectional light absorption and emission.

About Me
- Mark Waterbury
- Hi, some credentials, so you'll know that I know what I'm talking about. I've got 4 science and engineering degrees, including a Ph.D. in materials science and 20 years of experience. I've been a scientist for the Air Force, an engineer for a major engineering firm, and CTO for two companies. I've developed a number of measurement techniques, hold several patents, and have worked on a wide range of scientific projects. I've performed technology reviews for some of the largest companies in the world, sorting through claims of scientists and engineers and communicating the results to lay persons. I've worked in the brand integrity field, what is commonly called, "anti-counterfeiting" for several years. I've recently started my own firm, Perception Development Co., (www.percdev.com) and am now providing consulting services and developing a variety of new products and technologies.
