How to change... an FSL light?

For the love of god, does anyone know how to change this fluorescent light? Should I remove the rubber and then twist it by 90 degrees like the normal ones or what? I tried twisting but it felt like it was going to break so I stopped. Should I remove the metal part that's holding the rubber? I've changed FSL lights before, but I'm a noob for this one.

Also, could I just buy the same LED light or does LED need an additional adapter/something else?
