## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    was needed, came on time, installed correctly as expected
  

*by A***R on Reviewed in the United States 🇺🇸 on June 6, 2022*

We ordered this item because its brand is the same as our light fixture. Our analysis suggested we needed the ballast. We ordered it and the right item came quickly. We installed it and it worked. How much better could that have been. Only if an installer came with it. We are happy.

    Excellent Ballast
  

*by R***0 on Reviewed in the United States 🇺🇸 on August 7, 2016*

I bought this product a few months ago. It was an exact replacement to our old ballast. It was easy to install, although I do wish the wires were a little longer. However our fixture is quite long.  It has been working perfectly, with no flickering. I would highly recommend!!
