Sunset Light Bulb — Warm, Ambient Glow LED Bulb

Blocks blue and green light. Not just blue.

Melanopsin, the photopigment driving melatonin suppression, is sensitive from 400nm to 550nm covering both blue and green wavelengths. Most "blue light blocking" bulbs only block blue, leaving green light to send a daytime signal through the same pathway. The Sunset Bulb removes both, leaving only red-spectrum light that doesn't meaningfully activate melanopsin.

Zero flicker. Low EMF. Non-dimmable by design.

Dimmer switches introduce electrical instability that creates flicker, even when invisible to the eye. The Sunset Bulb delivers stable, consistent red-spectrum output at all times. 7W, 100-240V global compatibility, 50,000-hour lifespan. No pulse. No variation.

Half of a complete circadian lighting system.

Pair with the Yellow Light Bulb for daytime (reduced blue, not eliminated) and switch to the Sunset Bulb after dark. Add EMR-TEK blue light blocking glasses for screen use. Red-spectrum evening light is what humans evolved under after sunset. Firelight, not LEDs.
