Our Suncatcher light therapy lamps deliver up to 10,000 LUX of 5800K light to maintain energy and productivity lost due to disruptions in your circadian rhythms that occur from inadequate access to natural daylight. This lamp offers three light intensities - 10,000 LUX, 7,500 LUX and 5,000 LUX- to maximize your comfort. Find the one best suited to your needs. Customize your sessions by using different intensities at different times of the day or by using a lower intensity for longer sessions and a higher intensity for shorter ones. The 100 LEDs last up to 50000 Hrs. Our Suncatcher™ Light Therapy products leverage the best LED technology to help people of all ages fight the winter blues. The proven LED technology helps many customers get through the long winter months when there is a lack of sunshine, at the office without direct sunlight, and working from home while remaining productive. A lack of sunlight can have a negative effect on our well-being and can cause health issues related to a lack of light.
