Artemide Tolomeo Diffuser is a satin fabric shade designed by Michele De Lucchi for the Tolomeo range. The diffuser is a truncated-cone (frustum) shade with a 360mm diameter that sits over a lighting module to shape and soften the fixture’s output.

The form is deliberately minimal and architectural: a clean, seam-free satin exterior in a pale grey/off-white tone surrounding a rigid frame that preserves the frustum profile. The satin (raso) surface gives a muted sheen suited to considered interiors.

Construction combines a rigid internal frame with a metal top-mount assembly. The top incorporates a pivoting joint that allows the shade to be angled on its arm, and the electrical cord enters through the top mounting point consistent with Tolomeo-style fixtures.

Light is delivered downward through the open base while the translucent satin sides diffuse light to reduce glare and provide a soft ambient wash. The design is intended to balance task directionality with a gentle side glow.

The diffuser is rated IP20 for indoor use and carries a five-year manufacturer warranty. It is supplied as the shade component and is intended to be mounted to a compatible Tolomeo top-mount interface; check the host fixture for lamp, driver and dimming requirements.

Lighting Design Online recommends this diffuser when you want a restrained, high-quality shade that clarifies intent: it neatly controls glare, provides a calm ambient layer and pairs with Tolomeo arms for a coherent finish.
