The only company to buy a light box from. They were the essentially the first to market with this item, and the founder and president is someone who knows and cares about the suffering caused by seasonal affective disorder (SAD) and other forms of depression. You will get excellent, responsive customer service and prompt shipping from SunBox. They stand by their products and it is very refreshing to deal with a company where you can talk to actual people when you call! Cannot recommend highly enough.
