Universal Fluorescent Ballast - 18W | 120-277V AC | Programmed Rapid Start

The Universal Fluorescent Ballast, model C218UNVMES, is the component described here. The role of this model is to operate the corresponding fluorescent lamp arrangement within a compatible fixture. The 1 or 2 X 18W CFL operating configuration distinguishes this ballast from versions intended for a different lamp count. This is the programmed start version, so the fixture wiring and lampholder arrangement must suit that starting method.

Plan the electrical connection around this model’s 120-277V AC rating. For the ballast compartment layout, allow for the listed length 4.94 in., width 2.31 in., height 0.98 in. and the installation clearances required by its instructions. Follow the wiring diagram for this model when making the replacement connections.

Buying tip: Match the lamp designation, number of lamps and supply voltage to the existing ballast.
