Different people react to light differently. Some of us need lots of light to experience its benefits and some of us just need a little light to experience the same benefits. For this reason, there are HappyLight® models that allow you to customize the light.
The HappyLight® Liberty Full-Size Light Therapy Lamp has a high energy lens for full brightness and a comfort lens for a diffused light. The two lenses allow you to customize your light therapy experience and use what feels most comfortable for you.
It also has a high and low-intensity control. If you are facing your HappyLight®, the far left is high intensity (II) and the far right is low (I).
If you are interested in the light intensity (i.e., lux measurement) for the different settings, here they are:*
HappyLight® Liberty Full-Size Light Therapy Lamp
- High Energy Lens on High Intensity: 10,000 lux
- High Energy Lens on Low Intensity: 7,500 lux
- Comfort Lens on High Intensity: 5,000 lux
- Comfort Lens on Low Intensity: 3,500 lux
*These measurements are for using the light at a distance of 6” (like while reading a book and having the book between you and your HappyLight®) for 20-30 minutes. If the distance increases, then you’ll want to increase your usage time to get the equivalent benefits of the lux measurements above.
