How Do I Get 10,000 Lux?
10,000 lux is the recommend amount for effective light therapy. For most HappyLight models, you will receive 10,000 lux if you sit in front of the lamp at a distance of no more than 24 inches for 30 minutes. However, everyone's sensitivity to light varies, so you can vary distance and timing to get the right result for you.
Greater light intensity + shorter distance = shorter session times
Less light intensity + longer distance = longer session times
If a smaller amount of light is reaching your eyes, then you need to sit in front of your light therapy lamp longer to get more lux. If a larger amount of light is reaching your eyes, then you don't need to sit with your light therapy lamp as long to get the same amount of lux output.
