Sunday Light
Sunday Light recreates the experience of standing beneath a clear blue sky on a sunny day, delivering a biologically powerful light stimulus designed to support long-term health and human optimization. At its core, a high-performance LED generates over 34,000 lumens, cooled via a water-based thermal system to maintain consistent output and spectral purity. Just 30 minutes of exposure meets the recommended daily light intake, with research showing improvements in cognitive processing speed, alertness, focus and neurological performance.
By dynamically adapting to the body’s natural circadian rhythm, Sunday Light acts as a daily longevity intervention. Its variable colour temperature from 6000K energizing daylight to 2650K calming firelight—and continuous dimming help optimize hormonal regulation, supporting morning cortisol activation, serotonin balance and evening melatonin production. This contributes to deep sleep quality, metabolic stability and long-term recovery, key markers in longevity science.
The large reflective panel diffuses light in the same way the atmosphere does, creating a soft, sky-like glow with a natural sun point. This immersion enhances mood, reduces stress and restores biological alignment, transforming artificial indoor lighting into an active wellness stimulus that rejuvenates the body and strengthens resilience over time.
