The Dayvia Sundesk has been designed for flexible use of light therapy at the workplace or at home. The lamp head is adjustable. For therapeutic use, it can be directed towards the face to unleash the full medical effect with intense white or blue light. During the rest of the day, the Sundesk can be used as a desk lamp with a tilted lamp head and dimmed light. The combination of two different LED modules allows for a flexible and optimally tailored light quality according to current medical recommendations. Various combinations of white or white and blue light can be adjusted. Operation is conveniently done via switches on the side of the lamp head. The duration and timing of use depend on the desired effect. A light setting without medical effect allows for use as desk or ambient lighting throughout the day. The light is free from UV radiation. The Dayvia Sundesk is a certified medical product.
