The Litebook Elite is the new generation of light therapy, the result of years of research and development in hand-held light therapy devices. This new model features a custom lens and diffusion system which, combined with the high-performance white LEDs that all Litebook products are known for, produces a uniform field of bright yet soothing light. Additional new features for the Elite include a multiple-setting timer (15-30-45-60 minutes) and a long-lasting built-in rechargeable lithium-ION battery with a charge indicator all of this in a compact, sleek, new design which fits into your lifestyle. When used every day, the Litebook Elite will improve your mood, increase your energy level, and restore your sleep patterns. Most people notice results within 30 days - often sooner.
