Spec-reviewed for commercial installs

Brandon Waldrop

Lead Commercial Lighting Specialist • Spec Verification + Project Documentation

SLG’s 2×4 backlit LED panel is reviewed for thermal/optical stability from a backlit architecture, field-tunable performance (30/40/50W; 3,540–5,600 lumens), and adjustable CCT on a universal 120–277V driver so grid ceilings stay uniform without edge shadowing, mixed color, or early optical drift.

Spec review focus:
Verified for backlit performance benefits using a backlit architecture that supports more consistent thermal behavior and stable light distribution versus edge-lit designs; verified for field-selectable wattage at 30W / 40W / 50W to right-size light levels by space without changing fixtures; verified for output range of 3,540–5,600 lumens with max performance of 5,600 lumens at 50W for larger rooms and higher illuminance targets; verified for adjustable CCT selection (3500K / 4000K / 5000K) to tune the visual tone on-site from warmer to cooler environments without mixed-tone ceilings; verified for commercial electrical readiness using a 120–277V universal input driver for standard facility power conditions; verified for ceiling-uniformity intent where stable optics and right-sized output reduce hot spots and “checkerboard” brightness patterns.

Verified configuration:
Because wattage and CCT are field-set, document the final selections per room/zone so future swaps don’t create warm/cool or bright/dim tiles in the same ceiling. Also confirm the panel is seated flat and square in the grid; small tilt or uneven seating can show as a brightness edge in long sightlines, even when the backlit optics are performing correctly.
