Here is the type of light I had a handyman install in my dining room.
It was working fine for about 2 months and one night when I turned it on I heard a pop sound and two of the three lights went out. I bought new light bulbs, (exact same kind that were previously used) and they didn't work either. I also tried the old bulbs in the pendant light that still worked and the old bulbs worked in it. Is there any other info need to help solve this and is there anything I can try before calling an electrician?
