The Litebook® Elite™ is the new generation of light therapy. 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. The sleek design also offers additional new features such as a timer (15-30-45-60 minutes) and a rechargeable lithium-ION battery. The built-in battery provides up to 2 hours of light fully-charged; recharge at night like your cell phone. The Elite™ includes carrying case and 110-240v AC adapter with set of 4 international plug pins for use worldwide.
