I NEED A REPLACEMENT BALLAST FOR ADVANCE TRANSFORMER R-2S40-TP F40T12 / RS 48" 40W 430MA--34W 460MA

I NEED A REPLACEMENT BALLAST FOR ADVANCE TRANSFORMER R-2S40-TP F40T12 / RS 48" 40W 430MA--34W 460MA
Asked by: Djdoms
If you have, and want to retain, T12 48" bulbs then this ballast is not for you. If you have T8 bulbs, or are willing to trade in your T12s for T8 bulbs, then this ballast is a very good choice at a very good price. I swapped out my magnetic T12 ballast, removed all existing wires, and rewired it as shown in the documentation + one jumper and it worked like a charm. Instant on, instant off, no hum. Be sure to recycle your old ballast at your local recycle system; it is likely full of nasty stuff.

AmbiStar 40-Watt 2-Lamp T12 Rapid Start High Frequency Electronic Replacement Ballast is rated 4.2 out of 5 by 57.
Rated 4 out of 5 by from Replacement for Tar Magnetic ballasts I replaced 6 tar magnetic ballasts with these electronic ballasts in a country church. The power to the church must be pretty unstable; because the old ballasts are starting to go quite regularly now. The church was built in the mid 80's with about 40 T12 double lamp surface mount fixtures. I have yet to have a failed electronic ballast from Home Depot. I am sticking with 34w T12 48" bulbs as I have no desire or budget to convert the church to better fixtures.

The only wiring chart was a tiny diagram printed on the actual ballast that I could not read even with reading glasses. The Phillips website did not provide any useful information.

Suggest labeling wires from old ballast to make it easier to connect new ballast. Lamps must be installed prior to returning power to fixture.
