What this bulb is and who it fits

The Ushio CF13DE/827 is a 13W compact fluorescent lamp with a 4-pin base designed for electronic ballasts. It produces 900lm at 2700K with an 82 CRI and a rated life of 10000h. Suitable for fixtures that accept dimmable double-tube CFLs.

Practical limits of the 4-pin electronic ballast

This lamp requires a compatible electronic ballast that supports dimming; it will not operate on magnetic ballasts or direct mains voltage. The 4-pin base prevents insertion into 2-pin sockets used for pre-heat or rapid-start gear. Dimming performance depends entirely on the ballast’s dimming curve and minimum load.

The specification that decides fit

The 4-pin base and 13W rating are the decisive factors: the fixture must accept a 4-pin double-tube CFL and its ballast must be rated for a 13W dimmable load. If the socket is 2-pin or the ballast is non-dimmable, this lamp will not work.
