Within Flos Wall Lights, Clessidra introduces a compact architectural gesture defined by balanced emission above and below the fixture. Designed for indoor use, the lamp creates diffused direct and indirect light that shapes the wall with a controlled luminous rhythm rather than a single frontal beam. Two versions are available, with 20°+20° or 40°+40° distributions, allowing the effect to move from a sharper graphic accent to a broader wash of light. The Clessidra 20 up-and-down wall lamp is particularly effective in corridors, living areas, hotel spaces and professional interiors where illumination must support orientation, atmosphere and architectural continuity without adding visual clutter.

Antonio Citterio and the discipline of double emission

Designed by Antonio Citterio, Clessidra reduces wall lighting to a precise relationship between proportion, beam control and surface illumination. The symmetrical upward and downward output creates a measured visual effect that can reinforce circulation routes, frame architectural details or add depth to a quiet wall. The 20° version produces a more concentrated pattern, while the 40° configuration spreads the light more broadly for a softer result. This flexibility makes the Clessidra architectural wall light suitable for refined residential projects as well as hospitality and contract environments where repeated fixtures may be used to establish rhythm. Its compact shape remains discreet, allowing the luminous effect itself to become the dominant visual feature.

Flos Clessidra: aluminium precision and integrated LED performance

The Flos Clessidra LED wall lamp combines technical efficiency with the material clarity associated with Flos. A die-cast aluminium body gives the fixture structural precision and durability, while PMMA diffusers soften the direct and indirect emission for a comfortable, controlled result. The integrated power supply keeps the installation visually clean, and the LED source can be replaced by a qualified professional to support long-term maintenance. Finished in white, the body integrates naturally with contemporary walls and architectural surfaces, making the lamp easy to specify in both minimal interiors and more layered schemes. Its compact profile helps preserve open sightlines while delivering a clearly defined lighting effect.

Layered interiors with Flos Ceiling lights

Combined with Flos Ceiling Lights, Clessidra can form part of a coordinated lighting strategy in which wall-mounted and overhead sources define different layers of brightness and atmosphere. Its double emission is especially effective in passageways, stair areas, bedrooms, lounges and hospitality settings where soft guidance and decorative wall illumination are needed at the same time. The Clessidra modern wall light offers architects and interior designers a choice between tighter and broader beam distributions without changing the visual language of the fixture. With its durable aluminium construction, replaceable LED source and understated geometry, Clessidra delivers a refined balance of performance, visual restraint and contemporary Italian design character, allowing light to become an integral part of the surrounding architecture.
