## Customer Reviews

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    make sure it works
  

*by A***R on Reviewed in the United States on May 12, 2019*

I ordered two before and did not realize that one was defective.  I thought the problem was the light fixture.  When I tried the (working) transformer on the "bad" light, it worked.  By that time, it was too late to look into returning it.  I bought a third one from this seller and it works.  2 out of 3 is not five stars.
