Performance & Light Output

The MASI20 delivers incredibly powerful downlight illumination with a maximum output of 31,640 lumens and an outstanding efficacy of up to 166.8 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 and a B3-U0-G3 bug rating, this luminaire provides clear, uniform light distribution while maintaining strict uplight control to eliminate light pollution.

Electrical & Controls

Equipped with a constant current, Class 1 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. The internal electronics are fortified with 6kV 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 3G vibration tested per ANSI C136.31 and supports an extreme operating temperature range of -40°F to 122°F.

Installation & Mounting

The MASI20 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.
