Electronic CFL Ballast for Compact Fluorescent Lamps

This Lumapro 4KGJ7 electronic ballast operates compact fluorescent lamps at 120 to 277V AC input voltage. It supports one or two T4 spiral bulbs with a maximum of 13 watts each. The programmed start method provides reliable ignition for compatible CFL fixtures in commercial or residential settings.

Thermals Noise and Power Consumption

The ballast draws up to 30 watts while driving connected lamps within the specified wattage range. Electronic circuitry operates silently without the audible hum associated with magnetic ballasts. A minimum starting temperature of 0 degrees Fahrenheit ensures dependable cold-weather performance for indoor installations.

Build Integration and Compatibility

Carbon steel housing provides structural rigidity for surface or recessed mounting in standard lighting enclosures. The unit requires no dimming controls as dimming is not supported on this model. Installers must verify fixture compatibility with T4 spiral lamp types and the programmed start characteristic before wiring.

Questions about this item

How do I wire the 120/277V input on this electronic CFL ballast?

Connect the line and neutral to the 120 to 277V AC terminals matching your supply voltage; the programmed start circuit handles the rest for one or two T4 spiral lamps up to 13 W each.

What component will likely need replacement first on this ballast?

The electronic ballast itself is the wear item; once it fails the T4 spiral lamps will not start, so plan to replace the whole unit.

What thermal limit appears first during continuous operation?

The minimum starting temperature is 0 Degrees F; below that the programmed start may not ignite the lamps reliably.
