Spec-reviewed for commercial installs

Brandon Waldrop

Lead Commercial Lighting Specialist • Spec Verification + Project Documentation

Keystone’s 4-foot wraparound LED ceiling fixture with power select (18W/28W/44W) is reviewed for full-wrap distribution that fills rooms evenly, right-sized lumen tuning (2,664–6,116 lumens), and clean surface-mount practicality, with CCT select (3500K/4000K/5000K), 0–10V dimming on 120–277V, and a damp-rated build so restrooms, corridors, and utility spaces stay comfortable and consistent without glare streaks, mixed Kelvin, or over-lit small rooms.

Spec review focus:
Verified for broad, wide distribution using a full wrap lens that spreads light across the room and reduces harsh “bright-center” hot spots common in narrow optics; verified for field right-sizing with 18W / 28W / 44W selectable to tune brightness by ceiling height and space type (corridor vs. storage vs. restroom) without swapping fixture families; verified for scalable lumen delivery across 2,664–6,116 lumens—enough range to cover low-output utility needs through higher-demand back-of-house areas; verified for site-wide color matching via CCT tunable 3500K / 4000K / 5000K to keep a consistent white point across a wing and avoid phased-upgrade mismatches; verified for controls integration with 0–10V dimming to support occupancy sensors, scheduling, and high-end trim while maintaining a stable visual appearance; verified for low-profile surface mounting that keeps ceilings clean in spaces without grid systems; verified for damp-location suitability for restrooms and utility areas where occasional moisture is expected; verified for commercial electrical flexibility on 120–277V and 80+ CRI for readable labels and comfortable everyday task visibility.

Verified configuration:
This wrap fixture is configurable in wattage (18/28/44W) and CCT (3500K/4000K/5000K) and may be dimmed via 0–10V, so document “as-built” settings per area before installing long corridor runs. Wraps make inconsistencies obvious: one unit left at 44W or set to 5000K in a 4000K row reads like a bright or “different color” section immediately. Standardize Kelvin by wing, set wattage based on spacing and room function, and if dimming is used, keep trim levels consistent across the circuit so the run stays visually even after commissioning.
