About Vu1

Vu1 has done what lighting innovators have tried for centuries to do – create a lightbulb that provides a pure, warm, natural glow at the work surface without excess heat, energy or harmful components. It's Electron Stimulated Luminescence (ESL) technology is thought to be the first bulb to approach the ideal of lighting reflectivity defined by scientist Johann Lambert more than 350 years ago. The Lambertian principles spoke of light quality that had a full spectrum of colors, and reflected evenly on the surface below. Today, Vu1 has developed a lightbulb that operates as a Lambert Radiator, meaning the light appears brighter than the Lumens would indicate approaching Lambertian perfection – to consumers it is simply a bulb generating more light, using less energy, and with a purer glow.
