Rated 4.6 out of 5 by 8 reviewers.
Rated 5 out of 5 by No More Buzzing Dark, dark corner of the garage, and the only light there blew the ballast. It was an old transformer-type leaking oil. This new ballast, being solid-state, weighed nearly nothing in comparison. All the wires matched up in color perfectly. Physically fit the space. There. Done. And no more humming buzz to annoy me at all times. October 21, 2014
Rated 4 out of 5 by Easy to install This was very easy to install with matching wire colors to the ballast I was replacing. October 28, 2014
Rated 5 out of 5 by easy to install, lights up immediately, no humming sound, great price. went in store to get ge ballast, was not avail in store. so i picked up this one. i was hesitant at first but i am pleasantly surprised. with very little prior electrical experience, i cut the old wires, matched up the new ones twisted them together with old and put in wire caps with electrical tape to hold them in place. took 20-30 minutes to install. this is so much better than my old one that gave out. it lights right up immediately and no humming sound like the old one. i also installed a new set of t8 lights ge for "work spaces" its such a crisp bright white which lights up my kitchen instead of those old "warm" lights which are a dingy yellow color light they produce. makes all the difference in the world. wish i had changed these a long time ago. im very happy with my purchase and will update later if i have any problems.
