Spec-reviewed for commercial installs

Brandon Waldrop

Lead Commercial Lighting Specialist • Spec Verification + Project Documentation

Keystone’s LED 4-pin CFL replacement (2G11 base, 17W) is reviewed for direct PLL retrofit compatibility, delivering 2,200 lumens at 80+ CRI on 120–277V with an internal ballast-bypass driver, plus NSF rating for food-zone suitability and field CCT selection so linear CFL downlights and wall fixtures can be modernized without warm-up lag, ballast failures, or inconsistent color across a room.

Spec review focus:
Verified for true 4-pin PLL retrofit fit using a 2G11 base to replace common 4-pin PLL lamps without re-lamping guesswork; verified for stable LED operation via an internal driver / ballast-bypass approach to remove ballast variability and reduce a frequent failure point in older CFL systems; verified for practical light output at 2,200 lumens—a solid lumen tier for offices, corridors, lobbies, and back-of-house spaces where CFLs were commonly specified; verified for food-service readiness with an NSF rating, supporting use in areas where cleanability and material suitability standards are expected; verified for on-site color matching with CCT selectable (field-tunable color) to align with existing standards and prevent “one fixture looks different” outcomes during phased upgrades; verified for commercial electrical flexibility on 120–277V to simplify specs across mixed buildings and circuits; verified for usable color quality at 80+ CRI for comfortable recognition and day-to-day task visibility.

Verified configuration:
This lamp is configurable in CCT selection and is intended for a ballast-bypass (internal driver) retrofit, so document the “as-built” color setting per area and keep it consistent across each room or corridor run. The most common visual failure in CFL-to-LED upgrades is mixed Kelvin—one lamp set differently becomes the obvious outlier. Also label fixtures that have been converted to ballast-bypass so future maintenance doesn’t assume a ballast is present and accidentally reintroduce compatibility problems during replacement cycles.
