Performance & Light Output

The MASI16 delivers incredibly powerful downlight illumination with a maximum output of 23,442 lumens and an outstanding efficacy of up to 167 LPW. Built-in field-adjustable switches allow for seamless toggling between three color temperatures, ensuring visual consistency across various architectural environments. With a CRI of >80, this luminaire provides clear, uniform light distribution while maintaining strict uplight control to eliminate light pollution.

Electrical & Controls

Equipped with a constant current driver, this canopy light operates smoothly on universal 120-277V AC electrical systems. It features standard 0-10V continuous dimming, allowing for deep integration with advanced commercial energy management systems and compatible sensors. The internal electronics are fortified with built-in surge protection to withstand power spikes, ensuring reliable operation with a high power factor exceeding 0.90 and total harmonic distortion (THD) below 20%.

Construction & Durability

Designed to withstand harsh environments, the fixture features a rugged die-cast aluminum housing combined with a durable tempered glass lens and high-temperature silicone gasketing. It holds a strict IP65 rating, completely sealing the optical chamber against dust and water intrusion. Finished with an environmentally friendly white polyester powder coat, the luminaire is vibration-tested and supports an extreme operating temperature range of -40°F to 104°F.

Installation & Mounting

The MASI16 is engineered for streamlined surface mounting in commercial canopies and soffits. Its semi-recessed construction maintains a low-profile aesthetic while the integrated junction box includes four 1/2-inch NPS conduit openings for flexible wiring access. The field-adjustable switches are conveniently located to allow contractors to rapidly dial in the exact wattage and CCT during the installation process.
