Spec-reviewed for commercial installs

Brandon Waldrop

Lead Commercial Lighting Specialist • Spec Verification + Project Documentation

SLG’s 1×4 LED panel is reviewed for modular slim backlit integration, field-tunable performance (25/30/40W; 2,950–4,480 lumens) with selectable CCT, and glare-softening visual comfort with damp-rated reliability so narrow-grid ceilings stay uniform without harsh brightness, mixed color, or humidity-related interruptions.

Spec review focus:
Verified for space-efficient ceiling fit using a 1×4 slim backlit architecture that supports consistent illumination in narrow-grid layouts; verified for selectable wattage at 25W / 30W / 40W to right-size light levels per room and ceiling height without changing fixtures; verified for output range of 2,950–4,480 lumens to support corridors, offices, classrooms, and support spaces with controlled brightness; verified for tunable CCT selection (3500K / 4000K / 5000K) to align visual tone and task comfort across adjacent areas without mixed-color ceilings; verified for visual comfort using a diffused lens to reduce glare and soften contrast in occupied sightlines; verified for damp-rated suitability for indoor humid conditions (vestibules, restrooms, conditioned service areas); verified for 120–277V compatibility for standard commercial electrical conditions.

Verified configuration:
Because wattage and CCT are field set, document the final selections per zone so future swaps don’t create bright/dim or warm/cool “streaks” in a 1×4 run. Also confirm panels sit flat and centered in the grid; slight tilt or uneven seating shows up as a brightness edge along corridors and long sightlines—even when the backlit optics are performing correctly.
