Light engine
1,800–2,700 K Continuously variable, candle to dawnSerein 01 / Night instrument
The room learns night.
A physical instrument for deliberate sleep. Serein shapes the light and acoustic character of a room, quietly and continuously, from dusk until waking.
01 / The premise
Sleep is not an absence. It is an environment.
No screen.
No subscription.
No attention required.
A room, tuned over time
Acoustic field
24-bit Generative, non-looping sound architectureControl surface
One dial Turn for duration. Press for stillness.02 / One quiet sequence
It keeps time without showing it.
Set a waking hour once. Serein composes a nightly progression around it, reducing warm light, masking the uneven edges of the room, then returning brightness with restraint.
22:40 / Settle
03 / Architecture
Quiet, made physical.

Every element exists to soften interruption: a light source hidden from the eye, a speaker array that avoids a point of origin, and controls legible by touch.
Four reflected emitters create illumination without a visible LED point.
Machined brass beneath aluminium. A viscous rotation with no menu layer.
Six radial transducers disperse a low field evenly across the bedside plane.
Your sequence remains in the object. No microphone, account or cloud connection.
Built slowly. Used nightly.
04 / Making
Each Serein begins as a solid billet of recycled 6061 aluminium. It is cut, bead-blasted and anodised within sixty miles of our Portland workshop.
Assembled and acoustically calibrated by one technician.
Designed for disassembly, repair and a service life measured in decades.
05 / A reason to care
The finest sleep technology is the kind that asks nothing of you once the lights go out.
