What is BioCentric Lighting™?

BioCentric Lighting™ (BCL) by BrainLit simulates the important aspects of daylight, including wavelength, intensity, direction, timing, and duration, to sustain a healthy circadian rhythm.

What are circadian rhythms?

Circadian rhythms – often referred to as the “biological clock” – regulate our wellbeing, alertness and sleep. When we spend most of our time indoors, our circadian rhythms may struggle to synchronize without exposure to daylight. The solution is the BCL™ System – BioCentric Lighting™ invented by BrainLit – an intelligent lighting network solution mimicking natural daylight indoors to sustain the circadian rhythms.

What are some of the benefits from using BioCentric Lighting?

BioCentric Lighting™ environments by BrainLit directly counter the effects of circadian misalignment caused by lack of proper light exposure. As an intelligent lighting solution that accurately simulates natural daylight for human well-being, BioCentric Lighting™ uses algorithm-based light recipes to both balance and sustain the circadian rhythm. Benefits of a synchronized circadian rhythm as supported by BioCentric Lighting™ include:

  • Better sleep¹
  • Increased alertness²
  • Improved cognitive performance³
