The Caribbean Sun Box is a highly effective new light therapy light box that uses 108 LED lamps to treat the symptoms associated with Seasonal Affective Disorder (SAD). LEDs provide long life, pure white light, and are shock and vibration resistant. They serve to reduce the unit's size and weight, yet deliver a full 10,000 LUX of cool light while only using 9 watts of power! Plugs into 110-240V. Size is 9x 5x1-1/4. Put it on your desk or table top. Comes with a swing-out leg that allows you to position the box at a comfortable angle for best exposure. Take it with you when you travel. It has a carefully constructed enamel finish steel body, yet it weighs less than 3 lbs.
