The 2×2 footprint is specified where ceilings are laid out in 2×2 grid modules or where a smaller luminaire helps maintain spacing around diffusers, speakers, sprinklers, and access panels. Typical placements include corridors, private offices, exam rooms, classrooms, conference rooms, and retail support areas.
The selectable outputs are 2,250 lumens (18W), 2,500 lumens (20W), 3,125 lumens (25W), 3,750 lumens (30W), and 4,500 lumens (36W). This step range supports tuning by zone without changing the fixture body.
Each setting calculates to 125.0 lm/W: 2,250 ÷ 18W, 2,500 ÷ 20W, 3,125 ÷ 25W, 3,750 ÷ 30W, and 4,500 ÷ 36W. Delivered illuminance depends on ceiling height, spacing, reflectances, and any ceiling cavity losses.
Wattage selection allows light levels to be adjusted after installation to match a lighting schedule, accommodate changed room use, or correct for spacing constraints. This can reduce rework when a space is repurposed and keeps the ceiling layout consistent across a project.
3500K is often selected where a warmer visual appearance is preferred in occupant-facing spaces. 4000K is commonly specified for offices, classrooms, 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 operational targets without changing drivers or optics.
120–277V input supports standard commercial branch circuits, including 277V lighting circuits. This helps reduce voltage-specific SKUs on projects and supports consistent stocking across multiple sites.
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 environments.
An aluminum frame provides rigidity at the grid interface and supports 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 luminaire performance. Eligibility should be confirmed with the local utility program, 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.
