Spec-reviewed for commercial installs

Brandon Waldrop

Lead Commercial Lighting Specialist • Spec Verification + Project Documentation

Keystone’s 4-foot prismatic wrap LED fixture with power select (18W/28W/44W) is reviewed for glare-softening prismatic diffusion, right-sized lumen tuning (2,700–5,940 lumens), and controls-ready operation with 0–10V dimming on 120–277V, plus CCT select (3500K/4000K/5000K) and a 50,000-hour platform so corridors and utility spaces stay evenly lit without harsh brightness, mixed Kelvin, or fixtures that don’t play well with sensors and schedules.

Spec review focus:
Verified for anti-glare room fill using a prismatic lens that breaks up brightness and helps reduce “bright source” discomfort in line-of-sight installations; verified for field right-sizing through 18W / 28W / 44W selectable settings to tune illumination by ceiling height, spacing, and space type without changing fixture families; verified for scalable lumen delivery across 2,700–5,940 lumens to cover lower-output corridors through higher-demand back-of-house areas; verified for site-wide appearance control via CCT selectable (3500K / 4000K / 5000K) to match standards and prevent phased-upgrade color mismatch; verified for sensor and scheduling compatibility using 0–10V dimming so the fixture can participate in occupancy, timeclock, or high-end trim strategies instead of running full output continuously; verified for commercial electrical flexibility on 120–277V and 80+ CRI for practical recognition of signage, labels, and floor markings; verified for longevity and reduced maintenance with a 50,000-hour rated lifespan suited to high-use corridors and utility zones.

Verified configuration:
This wrap is configurable in wattage (18/28/44W), CCT (3500K/4000K/5000K), and 0–10V dimming behavior, so document the “as-built” selections per corridor/zone before installing long runs. Prismatic wraps make inconsistencies easy to see: one unit left at 44W or set to 5000K in a 4000K row reads like a bright or different-color segment immediately. Standardize Kelvin by wing, set wattage based on spacing and task level, and if sensors/dimming are used, keep trim levels consistent across the circuit so the run stays visually uniform after commissioning.
