A single long black linear light suspended on thin cables in a dark space, its white diffuser glowing and washing a plaster wall with soft light through faint haze.

Light, drawn straight.

One line of light, as long as the room.

Made to order in the profile size and length each project needs.

A bright, tall open-plan office with long, straight, slim black Diu linear lights suspended high under the ceiling above rows of oak desks, a woman working at a laptop and two colleagues talking in the middle of the room.

09:00 · The open-plan office

One floor, one even light.

Long, straight runs hang over the desks and carry the same calm, even light the whole length of the room, with no pools and no dark gaps.

Tunable white

Focus by day. Calm by evening.

Tunable white lets the same fitting give a crisp daylight white for the meeting and a softer warm glow once the day winds down.

A boardroom in cool daylight-white light: two long Diu linear lights above a walnut table, a woman presenting to four colleagues.
6500K, cool white
The same boardroom in warm evening light, the two Diu linear lights glowing amber over the walnut table and the same five people.
2700K, warm white

Tunable white adjusts from 6500K to 2700K.

Also available in a fixed 3000K or 4000K.

A floor people like to work on. Clients notice it on the way in.

A calm double-height reception at dusk with three long, straight Diu linear lights suspended above a timber desk, a receptionist greeting a visitor in a dark suit.

08:30 · Reception

A welcome that is lit before hello.

Three straight lines above the desk give the lobby a quiet, ordered warmth, and every face in the room is shown at its best at CRI 90.

A relaxed co-working space with one slim black Diu linear light suspended high above the room, four colleagues laughing and working together.

14:00 · The breakout area

Soft light for easy conversation.

Suspended over the long table and the sofas, the glow stays gentle and even, so the space feels as good for a catch-up as for a day of work.

A minimalist showroom with a single long Diu linear light mounted along the centre of the ceiling, washing a stone floor, ceramic vases on plinths and oak shelving, a customer browsing.

11:00 · The showroom

Lighting that lets the work speak.

One straight line down the middle of the room, an even wash for plinths, shelves and floor, and finishes that look the way they will in the customer's own space.

Straight lines. Soft light.

Installation: Recessed, Surface & Suspended.

A woman working at a large monitor in a quiet studio office, a slim black Diu linear light suspended high above her desk, the screen clear of reflections.

Low glare

Easy on the eyes.

A diffused light with a UGR rating of <19 keeps screens clear and desks comfortable, hour after hour.

Craft

A clean profile, an even glow.

A slim aluminium profile with a flat diffuser along the underside, so the light reads as one continuous line.

Down to a glow.

One line left on, dimmed low and warm. Dimming: DALI-2, On/Off. Rated hours: > 50,000hrs. Warranty: 5 Years.

Control

Every line, one system.

Diu runs on DALI-2, On/Off, so every run on the floor can be dimmed, grouped and tuned from one system, from the first meeting to the last light out.
