Your body needs different light at different times of day, that's meant either living under the same light around the clock or managing multiple bulbs, devices, and apps to approximate a natural light arc. The SunCycle solves that with one bulb. Full spectrum for the bright, clarity-supporting light your circadian system needs during working hours. Blue light-free amber at 1600K for the candlelight-range warmth that keeps melatonin safe as the evening unfolds. Pure red at 600–700nm for sleep-safe nighttime use when you need light without paying for it with lost sleep. Three modes, one E26 socket, one wall switch to cycle between them. No hubs. No apps. No friction between you and a light environment that actually works with your biology from morning to midnight.
