This fixture type is commonly specified for T-bar grid ceilings in offices, education spaces, corridors, healthcare support areas, and back-of-house retail where a uniform luminous surface is required across the ceiling plane.
The three wattage settings correspond to three lumen outputs: 24W delivers 3,000 lumens, 35W delivers 4,375 lumens, and 45W delivers 5,625 lumens. This allows light level tuning without changing the fixture footprint.
Efficacy varies by setting: 3,000 lumens at 24W is 125.0 lm/W, 4,375 lumens at 35W is 125.0 lm/W, and 5,625 lumens at 45W is 125.0 lm/W. Maintained workplane results depend on ceiling height, room cavity ratio, and surface reflectances.
An overall depth of 0.61 inches supports installation in ceiling systems with limited plenum space and can reduce conflicts with ductwork, cable trays, and other above-ceiling services. Verify clearance for driver placement and any junction box or whip routing required by the project.
3500K is commonly specified 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, inspection tasks, and higher-activity environments.
CRI 80+ supports accurate rendering for general office tasks, reading, and wayfinding. For color-critical work such as print matching or clinical evaluation, confirm whether the project requires higher CRI or additional color metrics.
0–10V dimming supports integration with occupancy sensors, time scheduling, and centralized control systems. It also supports commissioning trim so the installed light levels can be adjusted to the project target without replacing fixtures.
The 120–277V driver supports common commercial branch circuit voltages, including 277V lighting circuits. This can reduce voltage-specific SKUs across multi-tenant or multi-site projects.
DLC Premium listing is commonly referenced for utility rebate qualification and for documentation where third-party verification of performance is required. Confirm eligibility with the local utility program, since requirements vary by territory.
Damp-location rating covers humidity and intermittent condensation typical of restrooms, vestibules, 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, confirm site temperatures and select a fixture rated for colder ambient operation.
The fixture is rated for 50,000 hours and includes a 5-year limited warranty. For maintenance planning, document the selected wattage and CCT settings by area so replacements match light levels and appearance.
