Ushio BC2411 CF9S/827 9W 2700K CFL Bulb

The Ushio BC2411 CF9S/827 is a 9-watt compact fluorescent plug-in lamp designed for fixtures equipped with G23 2-pin sockets. It delivers 600 lumens of initial light output at a color temperature of 2700K, producing the warm white glow associated with traditional incandescent lighting. With a Color Rendering Index of 82, it renders colors reasonably well for general-purpose applications including desk lamps, wall-mounted fixtures, recessed downlights, and hospitality lighting where warm ambiance is preferred.

Rated for 10,000 hours of operation, the CF9S/827 offers a long service life that reduces maintenance frequency in commercial and residential installations. Its single-tube design keeps the form factor compact enough to fit in space-constrained luminaires, and the 9-watt power draw delivers meaningful energy savings compared to incandescent equivalents. As a plug-in CFL, it requires a compatible ballast within the fixture—it is not a self-ballasted screw-in type. The Ushio CF9S/827 serves as a dependable replacement lamp for existing CFL infrastructure where G23-socket fixtures remain in service.
