I had similar issues with Phillips. I bought six over a year for the relatively excellent quality of the light, but they'd start flickering after a month or two

I had similar issues with Phillips. I bought six over a year for the relatively excellent quality of the light, but they'd start flickering after a month or two. I had first suspected an electrical problem, but then tried them at entirely different locations in entirely different sockets and found the same. Haven't considered buying Phillips since and won't, ever. Nice light, shit construction.
