This fixture type is commonly specified for T-bar grid ceilings in offices, classrooms, corridors, healthcare support spaces, and retail back rooms where a uniform luminous ceiling appearance is required in a 2x2 footprint.
The three wattage settings correspond to three lumen outputs: 18W delivers 2,250 lumens, 27W delivers 3,375 lumens, and 36W delivers 4,500 lumens. This supports light level tuning without changing the fixture layout.
Efficacy is consistent across settings: 2,250 lumens at 18W is 125.0 lm/W, 3,375 lumens at 27W is 125.0 lm/W, and 4,500 lumens at 36W is 125.0 lm/W. Maintained workplane results depend on ceiling height, spacing, and surface reflectances.
An overall depth of 0.61 inches supports installation where plenum space is limited and reduces the chance of conflicts with ductwork, cable tray, and other above-ceiling services. Verify clearance for driver placement and the project’s wiring method.
3500K is commonly used where a warmer neutral appearance is preferred in offices and mixed-use areas. 4000K is a standard selection for general task lighting and circulation. 5000K is typically selected where higher contrast supports detail work and higher-activity environments.
CRI 80+ supports accurate rendering for routine tasks such as reading, labeling, and wayfinding. For spaces with color-critical requirements, confirm whether higher CRI or additional color metrics are required by the project.
0–10V dimming supports occupancy sensors, scheduling, and centralized control systems. It also supports commissioning trim so installed light levels can be adjusted to the project target without changing fixtures.
The 120–277V driver supports common commercial branch circuit voltages, including 277V lighting circuits. This can reduce voltage-specific variants across multi-tenant projects.
DLC Premium listing is commonly referenced for utility rebate qualification and for submittals that require third-party performance verification. Confirm eligibility with the local utility program, since requirements vary by territory.
Damp-location rating covers humidity and intermittent condensation typical of vestibules, restrooms, and other interior areas with elevated moisture. For direct spray or washdown conditions, a wet-location rated luminaire is typically required.
A 32°F minimum operating temperature indicates the driver and LED system are rated for operation at or above freezing. For unconditioned spaces that can drop below 32°F, select a fixture rated for colder ambient operation.
The fixture is rated for 50,000 hours and includes a 5-year limited warranty. Record the installed wattage and CCT settings by room or zone so replacements match light level and appearance.
