I was pushing them in and out - several times in fact!!
Didn't mean anything by it, just easily done, that's all....
Anyway, I'm out of ideas I'm afraid. The bulbs sound a bit unusual, but if they are 240V then they should be dimmable with no problems. Hopefully soemone cleverer will be along in a minute with some more ideas.
Good Luck !
