What is Lux?

Lux is a unit to measure the intensity of light. Indoor lighting might seem bright but is typically below 500 Lux. You can get 10,000 Lux outdoors in the summer or spring but in winter it can be difficult! That’s why all Northern Light Technologies bright light products provide 10,000 Lux. Just 30 minutes of 10,000 Lux can help you find the energy you need to thrive.
