Choosing a surface-mounted ceiling light that genuinely contributes to the atmosphere of a space — rather than just filling it — is harder than it looks. The risk is a fitting that either dominates the ceiling visually or disappears into it without purpose. Getting the balance right matters, especially in spaces where the ceiling plane is part of the design story.
In a surface downlight like this, light direction and diffusion method are the key specification decisions. Dual emission — light travelling both downward to the floor and upward to the ceiling — creates layered ambience rather than flat, single-direction illumination. DALI dimming (Digital Addressable Lighting Interface) means each fitting can be individually addressed and controlled as part of a wider lighting system, giving full scene flexibility without the compromises of simpler dimming methods.
The Stilnovo Oxygen Surface Downlight, designed by Pio e Tito Toso, delivers exactly this. Its PMMA (a high-clarity acrylic) diffuser ring uses OptiLight technology — laser micro-engravings that redirect photons from perimeter LED sources — to produce a downward task component and a soft upward aura that emphasises the ceiling plane. The open section between ring and base creates the impression the fitting is floating just clear of the ceiling surface. Rated IP20, it is suited to dry interior environments. The design earned a Red Dot Award in 2017.
The Oxygen is available in two sizes and four colourways: Yellow/White, White, Black/White, and Azure/White. Each combines a polyurethane ring shade in a bold or neutral tone with clean white upper and lower diffuser sections — a considered contrast that reads as architectural rather than decorative.
The fitting is DALI protocol dimmable, supporting integration into addressable control systems. For full installation and driver compatibility details, please contact the Lightsource Studio team directly, as driver requirements should be confirmed at specification stage to avoid on-site surprises.
At Lightsource Studio, we work with design professionals, self-builders, and business owners to make sure the right fitting reaches the right project at the right time. The Oxygen is the kind of considered specification choice — design-forward, technically capable, control-system ready — that repays the attention given to it. We can advise on sizing, colourway selection, DALI compatibility with your wider system, and lead times to keep your project on track.
