1×4 panels are specified in corridors, classroom rows, private offices, and narrow bays where the ceiling grid and furniture layout favor linear spacing. The 11.9-inch width also helps coordinate around diffusers, speakers, and access panels in tight ceiling plans.
The selectable outputs are 2,250 lumens (18W), 2,500 lumens (20W), 3,125 lumens (25W), and 3,750 lumens (30W). This range supports matching light levels across adjacent spaces without changing the fixture footprint.
Each setting calculates to 125.0 lm/W: 2,250 ÷ 18W, 2,500 ÷ 20W, 3,125 ÷ 25W, and 3,750 ÷ 30W. Delivered workplane levels depend on ceiling height, spacing, reflectances, and any ceiling cavity losses.
Wattage selection allows the same panel type to be set lower in circulation areas and higher in task areas during commissioning. This can simplify procurement for tenant improvements while maintaining the lighting schedule intent.
3500K is commonly used in occupant-facing spaces where a warmer appearance is preferred. 4000K is a common baseline for offices and general circulation. 5000K is selected where higher contrast supports detail tasks, wayfinding, and camera monitoring consistency.
0–10V dimming supports integration with occupancy sensors, time scheduling, and centralized lighting control systems. It also supports commissioning trim so installed light levels can be set to operational targets without changing drivers.
120–277V input supports standard commercial branch circuits, including 277V lighting circuits. This helps reduce voltage-specific SKUs and supports consistent stocking across multi-site specifications.
Damp-location rating supports installation where moisture or condensation can occur, such as vestibules, restrooms, and certain utility areas. It is not intended for direct water exposure or washdown conditions.
An aluminum housing supports rigidity and alignment in the ceiling grid. The polycarbonate lens supports impact resistance during installation and during ceiling access for above-ceiling service work.
DLC Premium listing is commonly used for utility rebate qualification and for documentation requiring third-party verification of luminaire performance. Program eligibility should be confirmed with the local utility, since requirements vary by territory.
A 100,000-hour rating supports long replacement cycles in extended-hour facilities. For lifecycle control, document the selected wattage and CCT settings by zone and retain submittals so replacements match output and dimming behavior over the service term.
A -4°F minimum operating temperature indicates the driver and LED system are rated for cold starts down to that ambient temperature. For spaces that can fall below -4°F, confirm site conditions and any manufacturer guidance before specifying.
