Tacet 0.7 · Recessed 68 mm

You cannotsee a light.

Only what it lands on. So this page has no product photograph at the top — it has a room, and one fixture doing its work in it.

Beam

24° of nothing else.

The cut-off is where the light stops. Past it, the fitting gives you darkness on purpose.

Rise

Square law, not linear.

Dimming follows the eye, not the driver: perceived brightness tracks the square of the setting.

Landing

1.19 m of pool.

From 2.8 m, the beam lands as a circle you can measure. Everything here is computed from that geometry.

I — The body

Six parts, one of them visible.

A turned aluminium barrel, a driver that stays out of the ceiling void, and a louvre deep enough that the source never is.

Section — assembly68 × 96 mm

II — The cut-off

Light with an edge.

The louvre cells are 11 mm deep and 4 mm across. Past 40° from the axis they see metal, not source — so the fitting goes dark before your eye does.

Polar — luminous intensityUGR

III — Warm dim

Scroll is the dimmer.

Turn it down and the colour falls with it, along the black-body locus, the way a filament does. 2700 K at the top of the throw, 1800 K at the bottom.

The same fitting, three rooms.

One luminaire, one driver setting, three surfaces. What changes is not the light — it is what the room gives back.

Vein-cut marble, polished.

A specular floor returns the beam as a second, softer source. The corridor lights itself from below.

Board-formed concrete, raw.

Grazing light is the only way to read a surface. Every tread edge takes a line; the formwork grain comes back.

Hand-troweled plaster, warm white.

The most forgiving surface in the building, and the one that shows the trowel. A wash, not a spot.

Nothing rounded up.

Every figure below is computed in the page from the same model that draws the beam section and the polar plot — flux, solid angle, illuminance, and the locus.
