2×2 panels are commonly specified where ceiling grids use 2×2 modules or where layouts need smaller fixture footprints for corridors, private offices, exam rooms, back-of-house retail, and classroom perimeter zones. They are also used to maintain symmetry in ceilings with multiple diffusers, speakers, or access panels.
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 range supports matching light levels across adjacent spaces with different task requirements.
Each setting calculates to 125.0 lm/W: 2,250 ÷ 18W, 2,500 ÷ 20W, 3,125 ÷ 25W, 3,750 ÷ 30W, and 4,500 ÷ 36W. Workplane foot-candles depend on ceiling height, spacing, and surface reflectances.
Wattage selection allows the same SKU to be tuned during commissioning to meet target illuminance levels or to align with a lighting schedule when field conditions differ from the plan. This is useful when ceiling heights vary across a floor plate or when a space’s use changes after initial design.
3500K is often specified for occupant comfort in hospitality-adjacent spaces, lobbies, and mixed-use areas. 4000K is widely specified for offices, corridors, and general-purpose rooms. 5000K is commonly selected where higher contrast supports detail tasks, wayfinding, and camera monitoring consistency.
0–10V dimming supports integration with occupancy sensors, time schedules, and centralized lighting control systems. It also supports commissioning trim so installed light levels can be set to the project requirement after installation.
The driver operates on 120–277V, supporting standard commercial branch circuit voltages, including 277V lighting circuits. This helps reduce voltage-specific variants across projects and simplifies standardization.
Damp-location rating supports installation where moisture or condensation can occur, such as vestibules, restrooms, and certain utility spaces. It is not intended for locations with direct water exposure.
A metal housing provides rigidity at the grid interface, while a polycarbonate lens supports impact resistance during installation and during ceiling access for maintenance. This combination is commonly specified where tiles are removed frequently for service work above the ceiling.
DLC Premium listing is commonly referenced for utility rebate qualification and for documentation requiring third-party verification of performance. Confirm eligibility with the local utility program, since requirements vary by territory.
A 100,000-hour rating supports long replacement cycles in extended-hour operations. For maintenance planning, record the selected wattage and CCT settings by zone and retain submittals and control wiring documentation so replacements match light output and control behavior.
A -4°F minimum operating temperature indicates the driver and LED system are rated for cold starts down to that ambient temperature. For unconditioned spaces that can fall below -4°F, confirm site conditions and any manufacturer guidance before specifying.
