I am replacing a fluorescent lamp ballast. I bought the GE296HO-MV-N-DIY

Customer Question

I am replacing a fluorescent lamp ballast. I bought the GE296HO-MV-N-DIY ballast. It is for use with 2 F72T12 lamps. The ballast that I am replacing has only red and blue leads (no yellow). Should I just insulate the yellow wires and not connect them?

Craig :

No, if you look at the wiring diagram on the ballast, it shows two lamps and the yellow wires feed both ends on the two lamps, correct? This is a HO (high output) ballast for use outdoors in the cold. YOu would have to wire the end connectors on the fixture to match the ballast.

Craig :

Are you operating a sign outdoors?

Craig :

If not I would use a regular ballast that matches the one you have like this:

Craig :

What is the ballast number that you are changing out?

Craig :

I will find that same one for you
