For some people, 10,000 lux is just too bright. Therefore, we offer HappyLight® Therapy Lamps that provide a range of light intensities.
The HappyLight® Compact is 5,000 lux (perfect for longer usage on a desktop) and other HappyLight® models, like the HappyLight® Touch and HappyLight® Full Size, let you adjust the light intensity so you can find the amount of lux that's just right for you.
It's important to choose a light therapy lamp that's comfortable for you. Research at the National Institute of Health demonstrated that white light, anywhere in the range of 2,500-10,000 lux, is effective for treatment of winter blues.
