GE 74474 T12 Ballast

This GE 74474 electronic ballast drives one or two T12 fluorescent lamps ranging from F48T12 to F96T12. It operates on multi-voltage supplies from 120 to 277 volts, making it suited for commercial retrofit and maintenance projects where magnetic T12 units are being replaced.

Sustained operation

Parallel lamp operation keeps remaining lamps lit if one fails, while auto-restart and thermal protection maintain stability during long running periods. The unit meets Department of Energy minimum efficiency requirements and carries a Class A sound rating of 20 to 24 decibels for quiet performance.

Installation notes

Mounting dimensions are 8.9 inch length by .3 inch width with slots set .3 inch apart, allowing direct replacement in many existing fixtures. Wiring must match the instant-start topology and the normal ballast factor of 87 percent; the ballast is not compatible with T8 or T5 lamps or with rapid-start sockets.
