The Piazza is a robust and adaptable outdoor wall-mounted luminaire designed to deliver high-performance lighting with a unique distribution pattern, making it ideal for building perimeters, pathways, entrances, and a variety of urban and commercial applications. Engineered to provide precise illumination, Piazza casts a forward light throw of three metres and achieves spacing of up to 12–13 metres at typical mounting heights of 3 to 5 metres, ensuring well-balanced coverage along walls and walkways. With an efficacy of up to 130 lm/W, Piazza combines energy efficiency with optimal light placement, providing safety, visual comfort, and minimal light waste.
Constructed from high-quality materials, Piazza features a die-cast aluminium back-plate in anthracite (RAL7016) and a UV-resistant polycarbonate body in matching anthracite, paired with a textured clear polycarbonate diffuser. Its design is suitable for C5 environments, offering robust corrosion resistance according to ISO 9223:2012 standards without requiring additional coatings. The luminaire is IK10-rated for impact protection and includes captive tamper-resistant screws for secure and straightforward installation, while polycarbonate components provide additional resilience against outdoor conditions.
Piazza is available with multiple lumen outputs and colour temperature options to suit different applications and aesthetic requirements. The LCS LED technology version offers three lumen levels—900 lm, 1600 lm, and 2700 lm—with colour temperatures of 2700K, 3000K, and 4000K. The HFIX version provides fixed colour temperatures of 2700K, 3000K, and 4000K with selectable flux levels, while the CS LED option allows compatibility with emergency systems. A built-in CCT switch enables easy adjustment of the colour temperature during commissioning or throughout the luminaire’s lifespan, providing flexibility for creating the desired ambience and compliance with local lighting requirements.
The Piazza luminaire integrates carefully engineered optics to maximise visual comfort and energy efficiency. Its directional light distribution ensures that illumination is concentrated along building perimeters and pathways, with minimal upward light (less than 0.3%), effectively complying with Dark Sky principles and reducing sky glow and light pollution. The light beam is cast efficiently to both sides of walls and pathways, creating safe and pleasant environments while preserving nearby ecosystems and avoiding disturbance to residents.
For enhanced energy management, Piazza supports DALI dimming and integrated photocell control. The photocell sensor automatically switches the luminaire on below 50 lux and off above 100 lux, though alternative settings can be configured. This feature, along with optional lumen switching and emergency lighting compatibility, allows designers to optimise energy use while maintaining the desired level of illumination. Piazza’s performance-oriented design ensures bright, uniform light with minimal glare, while its versatility allows installation in demanding environments, including seaside locations or areas with high ambient temperatures.
Piazza’s installation is simple and adaptable. It can be mounted on walls using back plates, BESA boxes, or surface-mounted conduit, with Ø20 mm cable entries via rear or side conduits. Recommended mounting heights are between 3 and 4 metres, and the luminaire includes captive screws and accessible mounting points to facilitate quick and secure installation. Through-wiring is supported for most versions, except HFIX and E3D, making Piazza suitable for both new projects and retrofits in urban, commercial, and residential environments.
In summary, Piazza combines durability, aesthetic appeal, precision photometrics, and intelligent control options into a single, versatile wall-mounted luminaire. With multiple lumen and colour temperature settings, high efficiency, directional optics, vandal-resistant construction, and compatibility with Dark Sky standards, Piazza delivers reliable, sustainable, and visually comfortable lighting solutions for building perimeters, pathways, entrances, and a wide range of outdoor applications.
