VESPER.

Scroll is the dimmer.

A concept launch page for a fictional Milanese ceiling luminaire. There is no product shot at the top: there is a plaster room with one fixture in it, whose beam travels across the wall as you scroll. Scrolling is the dimmer — the light falls from 2700 K to 1800 K along the real black-body locus — and every figure on the page, from the 5,784 cd peak to the 1.19 m pool on the floor, is computed in the browser from one specification.

The piece, section by section

You cannot see a light — only what it lands on.

The beam

You cannot see a light.

One continuous film scrubbed by the scroll: a single luminaire pivots and its pool of light travels across the plaster, with a section through the beam, the floor illuminance profile and a crosshair on the lit pool.

The body

Six parts, one of them visible.

A macro of the turned aluminium barrel, with the assembly drawn as a hatched section — trim ring, opal lens, honeycomb louvre, reflector, board, heat sink — and the 96 mm depth dimensioned.

The cut-off

Light with an edge.

A polar plot of luminous intensity computed from the beam model, with the zone past the 40 degree cut-off hatched out: nothing is emitted there, which is why the glare figure is under 10.

Warm dim

Scroll is the dimmer.

The room relights as you scroll: a live Kelvin readout riding the Planckian locus from 2700 K to 1800 K, the square-law dim curve, and the flux and illuminance falling with it.

Three rooms

The same fitting, three rooms.

Marble, board-formed concrete and hand-troweled plaster under the same driver setting, each with its reflectance and the luminance it returns.

Photometrics

Nothing rounded up.

The whole specification, computed from the same model that draws the beam section and the polar plot.

Made honestly

VESPER is fictional and the Tacet 0.7 is not a product — nothing is for sale. The rooms and stills were generated with Google Flow (Omni 1.1 Flash, Nano Banana Pro); every movement in the films is theirs. The beam section, the polar plot, the Planckian locus and every number are computed in code. In the promo video the browser window, cursor and captions are drawn; the page is a frame-by-frame capture of the real site.
