From the founder

Why I built WILLUME.

For years I lived in rooms I loved during the day and avoided after dark. Like most rented places, every room came with one ceiling light and one switch — everything fully on, or fully off. The big light flattened every evening: too harsh to relax under, too fixed to move, never where I actually was.

I tried what everyone tries — string lights, cheap lamps, smart bulbs that needed an app just to feel calm. Nothing gave me the thing I actually wanted: control. Light that follows your evening — reading on the sofa, dinner at the table, winding down low and warm — without an electrician, an outlet, or a cable trailing across the floor.

So I built it. WILLUME exists because lighting is personal. The room shouldn’t decide how your evening feels — you should. Everything we make puts the control of light back in your hands: where it sits, how warm it glows, how bright it burns. One lamp at a time, we’re switching off the big light.

What our owners say.

The One replaced every lamp on my desk. One light, every color temperature I need, zero cables.
Daniel · Berlin
The One follows me around the flat — sofa for reading, table for dinner, windowsill when it rains. The big light hasn’t been on in weeks.
Mia · Stockholm
It charges on the desk by day and sits on the bedside table at night. One lamp, every room — our whole evening runs on it now.

Frequently asked.

How long does the battery last?+

Up to 18 hours on a single USB-C charge at medium brightness. A full recharge takes about 2 to 4 hours.

What does CRI 90+ mean?+

CRI (Color Rendering Index) measures how accurately a light source shows colors. CRI 90+ means colors look virtually identical to natural daylight.

Can I adjust the color temperature?+

Yes. The One Lamp adjusts continuously from 3000 K (warm candlelight) to 6000 K (cool daylight) with a single dial. No app required.

What is the return policy?+

The One Lamp comes with a 30-day in-home trial. If it doesn’t change how your evenings feel, return it for a full refund — no questions asked.

What’s in the box?+

Lamp head, desk base, clip-on mount, wall mount, and a USB-C cable — everything you need to move light around your home from day one.
