SATCO/NUVO LED Circline 16W T9 CCT Selectable 3000K/4000K/6500K G10Q Base 120-277V (S16511)

A drop-in LED replacement for FC12T9 circular fluorescent tubes, this 16-watt Circline lamp fits the same G10q four-pin socket used in larger kitchen ceiling fixtures and ring-shaped drum lights. Universal 120–277 volt input and dual-mode ballast handling let installers either leave a compatible electronic ballast in place (Type A) or bypass it entirely (Type B) — both routes are supported by the same SKU.

Color temperature is selectable on the lamp: 3000K for warm rooms, 4000K for neutral kitchen light, or 6500K daylight for utility spaces. Peak output is 2000 lumens at 4000K, enough to fully replace a 32-watt fluorescent circline while cutting power draw in half and lasting 50,000 hours.
