The Northern Light Technologies Boxelite is a large light therapy panel built strictly for stationary use. It features a broad surface area delivering full-spectrum, UV-free light. The unit uses fluorescent bulbs to create a comfortable, diffuse glow, preventing the harsh glare common in smaller LED models. It provides the recommended 10,000 lux of illumination at a 14-inch distance, allowing you to sit comfortably during treatment. The large surface ensures your eyes receive adequate exposure even if you move your head, making it highly practical for computer work. While it takes up significant desk space and lacks portability, its wide coverage area makes daily sessions easy to complete.

Delivers 10,000 lux at 7.9 inches

The Lumie Vitamin L is a slim, portable light therapy tablet. It delivers the clinical standard of 10,000 lux of illumination at a distance of 7.9 inches. The compact profile saves desk space and allows for easy transport between rooms or offices. Because of the shorter treatment distance requirement, users must sit closer to the screen to receive the full therapeutic benefit.


Finding the right light therapy lamp requires matching the device’s specifications to your daily routine and workspace.

Illumination Level

Effective light therapy requires a lamp capable of delivering 10,000 lux of illumination. Both clinical-grade boxes and portable tablets must meet this standard to properly regulate your circadian rhythm.

Treatment Distance

The distance you must sit from the lamp varies by model. Larger panels provide 10,000 lux at a comfortable 14-inch distance, while smaller tablets require you to sit as close as 7.9 inches to receive the same exposure.

Size and Portability

Your available desk space dictates the best lamp style. Broad surface panels offer wide light coverage but take up significant room and lack portability. Slim tablets save space and are easy to transport between rooms.

Bulb Type and Glare

Look for full-spectrum, UV-free light. Some large units use fluorescent bulbs to create a diffuse, glare-free glow, which prevents the harsh glare sometimes found in smaller LED models.
