How Calfyr works with your day
Choose your lamp
Curated full-spectrum fixtures for Norwegian interiors.
Set your rhythm
The Calfyr app builds a personalised light schedule around your sleep and mood.
Feel the shift
Most users notice a difference within 7 days.
Up to 80% of Norwegians report low energy or mood shifts in winter.
The science, without the waiting room
Bright full-spectrum light helps your body read morning, midday, and evening more clearly. Calfyr is built around circadian rhythm support, up to 10,000 lux output, and the same light pathway your body uses to regulate vitamin D. The app keeps the timing gentle, so the light feels like part of the room.
What early homes are noticing
“I stopped reaching for the coffee by 10am. The lamp is on the moment I wake up.”
“The evenings feel less flat now. I keep it low near the sofa and the room still feels calm.”
“The app made the schedule easy. I use brighter light before work and a softer setting after dinner.”
Questions before the light changes
Full-spectrum light includes a wider range of visible wavelengths than a standard bulb, closer to the balance you feel outdoors in daylight.
Calfyr combines high-output full-spectrum light with a schedule built around your sleep, wake time, and mood patterns, so the light changes with your day.
We are preparing the first Norway release for winter 2026. Waitlist members will receive launch timing and early access first.
Yes. The Calfyr companion app is planned for iPhone and Android at launch.
Calfyr is designed as home lighting, not a medical treatment. For children with light sensitivity, eye conditions, or medication concerns, ask a qualified clinician first.
