Introducing MOOD by Ellumiglow
Circadian Lighting. Automated.
MOOD automatically adjusts your smart home lights throughout the day to match the natural rhythm of the sun — warm and dim at night, bright and cool during the day.

Circadian Lighting
Designed for Your Biology
MOOD calculates sunrise, solar noon, and sunset for your exact location, then builds a smooth 24-hour lighting curve with over 280 data points. Your lights shift gradually from deep warm tones at night through golden hour warmth into bright daylight and back again.
You set it once and forget it. Your home follows the sun automatically.
Light that works with your body, not against it.
From 1800K deep amber at midnight to 6500K cool daylight at noon, MOOD generates a complete circadian profile tuned to your latitude, longitude, and timezone. Customize the warm floor, cool ceiling, and global time offset to fit your schedule.
Room-by-Room
Every Room. Its Own Rhythm.
Create light groups for every room or zone in your home. Each group runs independently with its own mode and timing offset.
Circadian Mode
Follows the sun automatically with per-room time offsets. Start dimming your bedroom 30 minutes before your living room.
Scene Mode
Lock any room to a specific mood. Movie night in the living room while the kitchen stays on circadian.
Manual Mode
Fixed brightness and color for any room. Full control via the quick-access tray with hue, saturation, and white blend sliders.
Seven Built-in Scenes
A Scene for Every Moment
Switch any room or your whole home into a purpose-built lighting scene with a single tap.

Wake Up Alarm
A Better Way to Wake Up
Set a gentle sunrise alarm with customizable duration and repeat days. MOOD ramps your lights through a natural color journey so you wake up gradually instead of to a blaring alarm.
In RGBW mode, the sequence moves from deep purple through blue, coral, and orange to full bright white over your chosen duration.
Customizable Duration
Choose from 5, 10, 20, 30, or 45 minute sunrise sequences. Short enough for a power nap, long enough for a gentle weekday wake-up.
Repeat Schedule
Set which days of the week the alarm activates. Weekday mornings, weekends only, or any combination you need.
Light Compatibility
Full Color and White Support
MOOD works with both tunable white and full color smart lights connected to Home Assistant.
CCT Mode
Tunable White
For warm-to-cool white bulbs and fixtures. Customize the warm floor (1800K) and cool ceiling (6500K) to match your bulbs. Clean circadian transitions with brightness and color temperature control.
RGBW Mode
Full Color
For RGB and RGBW LED strips, Pixel-Free LEDs, and color smart bulbs. Full hue, saturation, and white blend control. Unlock the full scene palette including party mode color cycling and animated campfire.

Built by Ellumiglow
15 Years of Lighting Experience
MOOD is built by Ellumiglow, a Portland-based lighting technology company with over 15 years of experience engineering light as a material. From electroluminescent panels on Disney stages to circadian smart home control, we approach light as something that should work for people, not just look good.
Light as a material. Not an afterthought.
MOOD was born from the same philosophy that drives all of our products: light should be intentional, integrated, and designed for the context it's used in. Your home deserves the same attention to circadian science that professional lighting designers bring to their work.
