What's Included

4" Retrofit Circadian Recessed Light Panel with detachable E26 screw in base.

Size: 1
3 Color Settings

Choose from full spectrum Daylight, amber Sunset glow, or the warmest (zero blue light emitting) Campfire setting.

Flicker Free

Our upgraded light technology produces zero flicker rate, allowing your nervous system to rest.

Circadian Friendly

Our 3 color settings emit light frequencies that correspond to our natural light sources, so we can keep our circadian rhythms in sync.

Switch Controlled

Simply toggle through our 3 color settings by switching the light off and on.


2700 CCT

The Daylight setting is designed to illuminate your home throughout the day, with a full spectrum of light frequencies to provide maximum visibility when you need it the most, emulating daytime sunlight.

The 2700K color temperature is bright, but still warmer than the average ceiling light. It has just the right amount of blues and greens to match up to morning and mid day sunlight, but is not stark or harsh.

Energizing and stimulating.


2100 CCT

The Sunset setting is a warm, amber glow that serves as the perfect bridge between late afternoon daylight and dusk.

It is meant to be used towards the later hours of daylight, and has less blue and green light output, which means the lighting won't be sending your brain signals that it is mid-day or inhibiting melatonin production.

Gentle, but illuminating.


1400 CCT

The Campfire setting has a fiery glow which emits no sleep disrupting blue or green light, and is the perfect setting to keep your circadian rhythm in harmony with nature.

The 1400k color temperature delicately coats the room just as if you were sitting by a bonfire, or a beautifully candlelit space.

You can light up your house or room without disturbing the natural processes that your body performs throughout the day to ensure proper sleep, hormone production, and nervous system regulation.

Relaxing and sleep promoting.
