A university library reading room in morning light, two large black Diu Forma rings suspended level above two long oak reading tables, students writing, reading and laughing at laptops.

08:45 · The reading room

Even light, page after page.

A ring over each long table spreads a calm, even light across every page and screen, with a UGR rating of <19 to keep glare off the work.

Tunable white

Bright for the morning. Warm for the late session.

In tunable white the same ring gives a crisp, cool light for a morning tutorial and a softer, warmer glow as the study session runs into the evening.

A library group-study table in crisp cool white light from one large Diu Forma ring suspended above it, five students working together with laptops and books.

Tunable white adjusts from 6500K to 2700K.

Also available in a fixed 3000K or 4000K.

A bright lecture-theatre foyer with three black Diu Forma rings suspended in a straight line high above the floor, each washing the white ceiling with a soft halo, students chatting as a lecture lets out.

10:50 · The lecture theatre foyer

Light up. Light down.

In the direct/indirect version each ring lights the ceiling as well as the floor, so a tall foyer feels open and bright between lectures.

A lively student hub with colourful sofas and beanbags, a cluster of slim black Diu Forma rings and hexagons suspended high above, four friends laughing over a phone and students walking past with coffee.

12:30 · The student hub

Circles and hexagons, overhead.

Rings and hexagons in one slim profile, hung as a cluster over the busiest room on campus, so the light becomes part of the place.

Rings. Hexagons. Triangles. Rectangles.

Profile sizes: 35x35mm, 50x50mm, 60x68mm, 60x80mm, 60x100mm and 80x125mm.

A busy campus café with a timber slat wall, three black Diu Forma rings suspended in a straight line above a long communal table, students and a lecturer talking over coffee and cake.

15:10 · The campus café

Warm light for a long coffee.

A line of rings over the communal table, and every face shown true at CRI 90.

A hub students choose to study in. Staff like working around it.
