Keystone’s plug-and-play 4-pin CFL LED replacement (11W, G24q/GX24q) is reviewed for ballast-compatible speed of retrofit, delivering 1,050 lumens at 80+ CRI with a vertical optic optimized for downlight cans, plus field-selectable CCT, so CFL downlights can be upgraded with minimal disruption while keeping room-to-room color consistent and avoiding the rewiring scope of ballast-bypass conversions.

Spec review focus:
Verified for true plug-and-play operation as a ballast-dependent G24q/GX24q lamp, enabling quick swaps in existing CFL cans when ballasts are in good condition; verified for downlight performance with a vertical optic designed to push light where recessed cans need it, improving usable illumination versus retrofits that throw light sideways; verified for efficient replacement sizing using 11W to stand in for 26W+ CFL classes, supporting energy reduction without moving to an under-lit result in common office/corridor cans; verified for on-site color standardization through selectable CCT (field-tunable color temperature) so phased upgrades don’t create “two different whites” across adjacent rooms; verified for practical output at 1,050 lumens—a solid level for smaller recessed downlights and general ambient zones; verified for everyday color quality at 80+ CRI for comfortable recognition and clean visual presentation in occupied spaces.

Verified configuration:
This lamp is ballast-dependent and configurable in CCT, so document both the ballast strategy (plug-and-play) and the as-installed Kelvin setting per area. The most common visual issue is mixed color temperature—one lamp left on a different CCT setting becomes the obvious outlier in a ceiling grid of cans. Also keep an eye on ballast health: if you see flicker, delayed starts, or inconsistent output between fixtures, it’s usually ballast aging—not the lamp—so plan a staged ballast replacement or a zone-based move to ballast-bypass rather than mixing strategies fixture-by-fixture.
