The Tesser 5:8 Lamp is built on the Fibonacci sequence, geometry doing double duty as light source. Ridezign, based in Brooklyn, builds it tall and narrow, the stacked, faceted form filtering light rather than just casting it, layered enough to catch a bit of that New York skyline glow at night.

Cast in the Guava colorway, by day the grid runs vibrant yellow and soft orange. Switched on, it glows warm, the kind of ambient light that suits a bedside table for reading in bed, or a desk that needs something softer than an overhead light.

No cord, no outlet needed. It runs on an internal battery for 25 to 30 hours a charge, so it goes wherever the room needs it that night.
