OIO Bulb uses a proprietary four color system called CLOV (Cyan, Lime, Orange, Violet) to create white light with or without blue. White light made with Cyan, Lime, and Orange will have a peak of energy right where your circadian system is most sensitive – 480 nanometers. White light made with Lime, Orange, and Violet will have effectively zero energy between 440 and 495 nanometers as the Violet is below that range and Lime is above it. By using only the Lime, Orange, and Violet LEDs starting at around 3 hours before bed, you can avoid the wavelengths that suppress melatonin and naturally fall asleep when ready.
