This 2×4 format is specified for suspended grid ceilings in offices, classrooms, corridors, healthcare support areas, retail back-of-house, and light industrial administrative zones. The 2.8-inch depth is relevant where plenum clearance must be coordinated with ductwork, cable trays, and other above-ceiling services.
Wattage selection allows one luminaire family to cover multiple design targets during commissioning. The installer can set 25W, 30W, 40W, 45W, or 50W to align with required workplane illuminance, spacing constraints, or changes in room use without changing the fixture count.
The selectable outputs are 3,125 lumens (25W), 3,750 lumens (30W), 5,000 lumens (40W), 5,625 lumens (45W), and 6,250 lumens (50W). These steps support matching adjacent spaces that have different light level requirements while keeping the same panel footprint.
Each setting calculates to 125.0 lm/W: 3,125 ÷ 25W, 3,750 ÷ 30W, 5,000 ÷ 40W, 5,625 ÷ 45W, and 6,250 ÷ 50W. Final delivered foot-candles depend on ceiling height, spacing, reflectances, and any lens or ceiling cavity losses.
3500K is often selected in occupant-facing and mixed-use areas where a warmer appearance is preferred. 4000K is commonly specified for offices and general circulation. 5000K is used where higher contrast supports task visibility, 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 the operational requirement without changing drivers or optics.
The driver operates on 120–277V, including 277V lighting circuits. This supports standard commercial branch circuits and helps reduce voltage-specific SKUs across multi-site specifications.
Damp-location rating supports installation where moisture or condensation can occur, such as vestibules, restrooms, and certain utility spaces. It is not intended for direct water exposure or washdown environments.
An aluminum frame supports rigidity at the grid interface and helps maintain panel alignment in the ceiling system. A polycarbonate lens supports impact resistance during installation and during ceiling access for above-ceiling service work.
DLC Premium listing is commonly referenced for utility rebate qualification and for documentation requiring third-party verification of performance. Eligibility should be confirmed with the local utility program, since requirements vary by territory.
A 100,000-hour rating supports long replacement cycles for 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.
