Rated 4.7 out of 5 by 6 reviewers.
Rated 4 out of 5 by The right product for the right job These Ballasts are smaller than the Old Style, but still fit in the same space and fixture mounts in Your Older fixtures. Wiring is the same as well... June 10, 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.
