I have 6 inch low profile LEDs in my renovation. Some are on dimmers. Clearly the electrician installed junk. They have begun to fail in only a few weeks. (Strobing. Not on dimmers.) He has done so many awful things that I don't want him back again. (Such as he drilled through the bottom of every kitchen cabinet when he installed the under-cabinet lights. The dimmers are also junk but I can just cope with them. He moved and mixed up my light fixtures when installing them.) I will have to ask my son to come over and do this for me. The drywall on the ceiling is soundproofed so very thick. It will be a bit tricky. My son will not be too happy about it. I want to replace them with something good that will be reliable for a long time. Can anyone recommend? Thank you.
