The Luna Red Sunset™ A19 Bulb is a true day-to-nighttime bulb that emits specific wavelengths of light to simulate natural light/dark cycles during a 24-hour period. The daytime settings cue vital circadian responses for better energy and focus, and the nighttime settings emit wavelengths akin to fire or candlelight to promote relaxation, natural melatonin production, and sleep onset. The Luna Red Sunset™ A19 Light Bulb is also dimmable and has a nightlight mode for convenience and comfort.
Other “circadian lighting” options on the market often use yellow or red painted dome light bulbs, which do not emit pure color tuned to any specific wavelengths. The LED illuminating the bulb is rich in blue light, and the painted coating that covers the bulb does not entirely block the junk light being emitted. Painted domed bulbs have a lower transmittance and Color Rendering Index (CRI) than the Luna Red Sunset™ A19 Light Bulb, which creates an eye-straining environment that subsequently appears dim and less appealing.
