Doc 01 · Product overview
Sunlight-quality light, engineered for architecture.
Sunlight, composed.
Ten channels · 440–750 nm
How it works
One module. Any composition.
A flat-top hexagon in machined aluminum, with a precision glass optic.
Tiles connect to each other magnetically, and the magnets do the aligning. Each tile seats flush by hand, no tools on site.
Arrays grow along any edge. Start with a cluster, extend a run, open a void in the center.
Add or reposition tiles after handover without touching the ceiling or the wall finish.
Spectral quality
Engineered to render like daylight.
Most white light is built from a few channels, which leaves gaps across the spectrum. Tesel uses a ten channel spectral engine to fill in that curve, so color is rendered rather than approximated.
Design target: TM-30 Rf ≥ 95*
*Design target. Measured spectral data to follow prototype validation.
The experience
Color and sunlight in one fixture.
01
Art reads as intended.
Pigment, glaze and patina hold their true color. Nothing flattens, nothing shifts as the light warms through the day.
02
Materials show their depth.
Walnut, travertine, brushed brass and raw wool keep the grain and warmth they have in daylight.
03
Skin looks like skin.
People read warm and even across a room, the way they do outdoors.
Applications
Made for spaces that are looked at closely.

One array, the whole day. Morning light for the arrivals, warm light for the last drink, and the same wall doing both. Nothing else in the room needs to change.

The first thing a visitor sees, and the first thing they read about you. Warm at the desk, cooler toward the glass, so the wall belongs to the window instead of competing with it. Move the desk and the tiles move too.

A room lit the way the day would do it. Full spectrum at breakfast, a long slow fade toward evening, and timber, skin, and paper looking like themselves the whole way through. Easy to live under. Hard to stop looking at.

Ten independent channels, so the shape of the spectrum is a design decision rather than a bin code. Coverage from deep blue to far red, past the point the eye can follow, so the reds in timber, skin, and textile hold instead of going flat. One tile size, and any array that tiles a plane.
Early access
Two conversations. One request away.
We are working with a small group of lighting designers, architects and specifiers ahead of launch. Tell us about the space and we will be in touch.
We will only use this to talk to you about your project.
Every request is reviewed personally before anything is sent.
