Circadian-aligned, spectrum-optimized, and built to fix what garbage hotel lighting, overnight flights, and screen exposure messes up.
High-performance circadian lighting, wherever you are.
The Sky Portal Mini is a portable, battery-powered light device designed to support alertness, sleep, and circadian health in the environments that usually destroy it – hotels, late work sessions – anywhere your routine breaks.
It uses the same dual-channel design as our full-size Sky Portal 2.1:
- Daytime White Channel – precisely tuned with 415nm and 480nm stimulation, with the entire blue light hazard zone around 450nm cut out. Wake up, stay alert, focus, and thrive.
- Deep Amber Channel – low-melanopic, low stimulation sunset amber with a boosted 660nm peak for circadian-safe use in the evening, and to balance the daytime channel during the day. Relax, be at peace, read a book, low stimulation to wind down for the day.
- Portable power: Over 30 hours of light on low. Doubles as an 8000mAh USB-C battery pack for your phone or other devices.
- Total control: Adjust total intensity and the ratio of Amber to White in 5% increments.
- ZERO FLICKER: No flicker at any brightness, we use constant current dimming, not high frequency PWM.
- Impact Where You Need It: Whether you’re waking up at 4am in a hotel or trying to stay sharp in a gray-lit coworking space, this lets you create the right light—anywhere.
Morning Reset
It’s designed to kickstart alertness, and set your circadian rhythm especially after travel or poor sleep. Best when used within 1-3 feet, in your line of sight.. Ideal for early risers, shift workers, or jet lag recovery.
Midday Focus
Reduce eyestrain, elevate focus, and keep overstimulation from screens in check. Mix in Amber to balance intensity. The included diffuser panel softens the light for screen-heavy sessions. Your brain runs better when the lighting makes sense.
Evening Wind Down
Switch to 100% Amber in the late afternoon or after dark. Supports melatonin production and helps signal that it’s time to slow down. Great for hotel rooms, bedrooms, kitchens, or anywhere you want to see clearly without being jolted by overheads.Light Designed For Humans
- No harsh blue spike. Most common white LEDs overload your brain with harsh dark blue light in the 450nm range. We cut it out entirely.
- Boosted red and near-infrared. Deep Red in our Amber channel and Near Infrared in the Daytime White channel support cellular energy and mental sharpness.
- True zero flicker. No eye fatigue. No headaches. No compromises.
