Compact fluorescent lamp for G23 fixtures

The Ushio CF5S/827 is a 5 W single-tube fluorescent bulb with a G23 two-pin base. It produces 250 lumens at a warm 2700 K colour temperature and carries a colour rendering index of 82. The lamp is rated for 10000 hours of operation and measures 4.30 inches in overall length.

Limits of the G23 two-pin interface

The G23 base fits only magnetic ballast fixtures wired for two-pin compact fluorescent lamps. It cannot be used in four-pin electronic sockets or in standard Edison screw holders. The integrated starter means the lamp depends on the fixture's magnetic ballast for correct starting and running characteristics.

Rated life of 10000 hours

A rated life of 10000 hours determines whether this lamp matches the maintenance cycle of the installation. Buyers needing a longer interval between replacements should note this figure. The 250 lumen output and 82 CRI are fixed by the 5 W design and cannot be increased in the same form factor.
