This video is how I removed my plug in cfl bulbs. I am not an electrician but a homeowner who encountered the difficulty in removing these bulbs without much resource on the internet on what to do. I hope that I am able to help someone out that encountered the same problem that I had. Just remember not to twist. Enjoy the video and thumbs up if it was useful to you.
