Bright morning light for natural energy

Most indoor lighting is too dim during the day, causing fatigue, brain fog, and seasonal affective disorder.

FL1 provides bright full-spectrum light to enhance your energy, focus, and productivity.

3.2x faster problem solving 
+ 10% boost in working memory

Harvard Medical School study

Warm evening light that protects your sleep

Your lighting disrupts your sleep with harmful blue light after sunset.

FL1 automatically transitions to warm, gentle light to promote melatonin for deeper sleep.

23% faster sleep onset 
and 1.5x deeper rest

THE RISKS

Your light damages your health, day and night.

We spend 90% of our lives indoors. Most lighting creates a dangerous mismatch with your biology: 

  • Too dim during the day when you need energy and alertness
  • Too bright and blue at night when your body needs to wind down
