Reduces blue light without eliminating it. Because you still need some. Standard LED and fluorescent lighting blasts a high-blue spectrum regardless of time of day, sending a constant midday signal to your circadian system. The Yellow Light Bulb brings indoor lighting closer to a natural, warmer daytime spectrum. Maintains the blue wavelengths needed for alertness and cortisol timing while cutting the excess. Zero flicker. Low EMF. Non-dimmable by design. Same stable architecture as the Sunset Bulb. 7W, 100-240V global compatibility, 50,000-hour lifespan. For a light you're using all day during working hours, flicker-free output isn't a luxury. It's the baseline. The daytime half of EMR-TEK's circadian lighting system. Yellow Light Bulb from morning until sunset. Sunset Bulb after dark. EMR-TEK blue light blocking glasses for any screen use. A complete indoor light environment built around circadian biology, not just brightness.
