This lumen package is commonly specified for stock rooms, utility corridors, maintenance areas, light-duty workshops, storage rooms, and back-of-house retail where a 4-foot form factor fits standard bay spacing and supports consistent ambient levels.
The fixture produces 5,200 lumens at 40W, which calculates to 130.0 lm/W. Maintained workplane light levels depend on mounting height, fixture spacing, and ceiling reflectance.
A 4-foot body is often selected when the ceiling layout requires shorter runs, when obstructions limit continuous 8-foot lengths, or when rows need to align with doors, racking breaks, electrical zones, or ceiling structure.
The ribbed frosted diffuser spreads the emitted light and reduces direct view of the LED array, which can lower perceived brightness at higher viewing angles. It also helps maintain a more uniform lens appearance across the fixture face.
3500K is often selected for mixed-use back-of-house areas that transition between public and service spaces. 4000K is commonly specified for warehouses and general task areas where a neutral white appearance is standard. 5000K is typically specified where contrast supports inspection tasks, label reading, and safety visibility.
0–10V dimming supports integration with occupancy sensors, time scheduling, and zone-based control strategies. It also allows light level trimming during commissioning to align measured foot-candles with project requirements.
The 120–277V driver supports common commercial voltages, including 277V lighting circuits. This can simplify specifying one fixture across multiple buildings or tenant spaces with different branch circuit voltages.
Damp-location rating covers areas subject to humidity and intermittent condensation, such as unconditioned storage rooms and covered service areas. For direct water exposure or washdown conditions, a wet-location or sealed vapor-tight luminaire is typically required.
cULus listing supports electrical safety certification for North American installations. In submittals, this is typically referenced alongside voltage range, dimming method, and location rating.
Record the lumen package, CCT selection, voltage, and dimming method used by zone. This helps keep light levels and appearance consistent when fixtures are added or replaced during future maintenance work.
