Two-tone drum ceiling light with a broad, even glow
Item 2
Item 3
The Datum is a clean drum ceiling light whose outer iron band and inner acrylic diffuser are finished in different tones, so it reads as two stacked discs rather than one solid lump. At 13cm deep it has gentle presence, and the diffuser spreads a broad, even light.
