Hi, I've an LED light in my bathroom that's failing. I was going to remove it but not sure how, and don't want to damage the fitting. Unlike my kitchen leds which have a twist fitting, the bathroom one has a silver (ish) ring around it. I've turned this anti-clockwise to pull it off but am not sure what to do next. The bulb doesn't push in and feels pretty tight and seems to have a plastic ring around it. I've tried twisting it with my fingers but it's not budging. Do I need a sucker to attach to it and just pull it out? Any help is appreciated, thanks
