The SQP400 is a 4.5-inch square-profile wall-mounted luminaire offering precise light adjustability through its 30° tilt and 355° rotation capabilities. With a powerful output of up to 3,000 lumens, it provides effective illumination in a sleek, architectural form. This fixture is part of the Syrios Pro family, which has been thoughtfully redesigned with a “curb to cube” design approach. This unified aesthetic allows for seamless visual continuity across architectural spaces. The collection includes a range of mounting options—wall, ceiling, pendant (via aircraft cable or catenary), and now a new pole-mount option—to meet various installation needs. Wall and pendant configurations can be specified for up, down, or up/down lighting.
Syrios Pro is available in two sizes, 4.5" and 6", and comes in both round and square profiles. It offers a selection of beam angles—6°, 15°, 30°, and 55°—to support a range of lighting applications, along with four IES roadway distribution types: Type I, II, III, and V. Suitable for outdoor environments, it is IP65-rated for wet locations and is DarkSky approved. Optional color outputs include true amber for turtle-sensitive areas (with a wavelength range of 585–597nm) and RGBW with quad-chip technology for optimal color mixing under each optic. RGBW configurations are available in 3000K or 4000K white.
The fixture features robust construction with a cast aluminum wall mounting box and a galvanized steel mounting plate for secure installation. The main housing is made from seamless extruded 6063 aluminum, while an asymmetric heatsink provides a balance of sleek aesthetics and effective thermal management. The up or down light assembly is crafted from sealed cast aluminum, ensuring durability and weather resistance. For precise beam control, the Syrios Pro includes either a faceted specular aluminum reflector for smooth, glare-reduced output or a TIR collimator lens for very narrow beam distribution.
Syrios Pro is built from corrosion-resistant 360 aluminum alloy, containing less than 0.1% copper to prevent degradation in harsh environments. Its integrally sealed LED light module ensures long-term performance and efficient heat dissipation. The fixture is equipped with a 0-10V dimmable driver (down to 1%) and supports multi-volt (120-277V, 50-60Hz) or high-volt (347-480V, 50-60Hz) electrical input. It includes protections against over-voltage, over-current, and short circuits, with auto-recovery functionality. Operating temperatures range from -30°C (-22°F) to 45°C (113°F).
LED options include 2700K, 3000K, 3500K, and 4000K color temperatures with 80 CRI, providing 70% lumen maintenance at 60,000 hours (L70/B50), verified using IESNA LM-80-08 data and extrapolated per IESNA TM-21-21. The finish process involves a five-stage surface treatment, including preheating aluminum parts to remove air pockets and the application of an environmentally friendly alloy sealant. A durable polyester powder coat is electrostatically applied and oven-cured, delivering a long-lasting finish that withstands outdoor conditions. Certified to UL standards for the U.S. and Canada, the Syrios Pro is verified for wet location use, with photometric testing conducted by an independent lab under IES LM-79-08 standards at 25°C. Performance results may vary depending on the installation environment.
