    A Do It Youself Project That Is Easy -
  

*by J***A on Reviewed in the United States on August 21, 2014*

After 25 years of use, the four florescent lights in my kitchen were taking way too much time to go on. Replacing the four foot, single bulb fixtures cost more than I was willing to spend, so the alternative was to replace the ballasts and this one does the job. Replacing the ballast was relatively easy as they attached exactly the same as the old ones and the wiring was "half" successful. The only problem I encountered was the blue wires to the end socket were too short by about a foot so I had to splice them to the old wires from the socket. I used some small wire nuts. The hot and neutral feed wires and the red pair to the far end socket were the appropriate lengths, although you could consider using wire nut splices there as well. When I turned the lights on and they all came on in a second, I smiled.

*by N***L on Reviewed in the United States on October 27, 2015*

Perfect fit replacement for the small 2 foot light under my cabinets in the kitchen. The wiring pattern was different than the 17 year old Robertson ballast I was replacing. Just followed the wiring diagram on the new ballast and everything works fine.

### ⭐⭐⭐⭐⭐ 







  
  
    Quiet, quick, easy installation, a bargain compared to replacing fixture.
  

*by L***R on Reviewed in the United States on February 25, 2016*

Worked like a charm.  Wires were long enough to fit in even a large fixture.  ZERO noise and starts right up.  Saved me $20 over the other option and installation was much simpler than replacing the entire fixture.
