Built based on Mayo Clinic research, this model meets clinical strength standards. It provides full-spectrum, glare-free white light and features a sturdy base with an adjustable angle.

This model delivers the recommended 10,000 LUX of light at a 12-inch distance. You can read or work on a computer while absorbing the light. Regular use improves sleep patterns and combats jet lag.

Broad light surface

The Northern Light Technologies Boxelite is a full-size clinical lamp that competes closely with the Carex model in size and effectiveness. It relies on fluorescent bulbs rather than LED technology to deliver the required 10,000 lux of light at a 14-inch distance.

Clinical Strength and Distance

A therapy lamp must deliver a clinical dose of 10,000 lux. Pay close attention to the required distance to achieve this brightness. Effective models provide 10,000 lux at a practical distance of 12 to 14 inches, so you do not have to sit uncomfortably close.

Size and Light Surface

Full-size lamps consistently outperform tiny light panels. A broad light surface ensures you receive the full benefit of the light therapy without needing to keep your head perfectly still while you read or work.

Bulb Technology

Therapy lamps generally use either LED or fluorescent bulbs. Both meet strict clinical standards for brightness and safety, allowing you to choose based on your preference for light quality.

Choosing the right SAD lamp requires prioritizing clinical strength and a practical sitting distance. Measure your available desk space and select the model that best fits your daily routine to start improving your winter energy levels today.
