    Universal Ballast (Received 3 ballasts.)

    Posted by Robert Schepis on Jun 29th 2019

    1 ballast sealed in plastic wrap, the other 2 had rubber bands, wire lengths different on each one, making me wonder if they were all new or some refurbished. Had to shorten wires on one ballast, and splice extra wires on the other two. Having said that, they all work great, lights go on instantly, no flickering, and are brighter than before.

    The ballast works great however the wires were not long enough on one side. Had to add wire. Other than that great lights quick and quiet.

    Replaced old style T12 ballast with these in 4-bulb fixture. A good price, but had to go purchase extra wire to splice in. Does not come with enough wire to attach to far ends and reach outer bulb connections.
