I have 14 of these push-in type compact fluorescent bulbs. They have four pins rather than screw fitting or bayonet. I used to live in a new-build flat where these were fitted. Some of the bulbs are new, some are used because I swapped them out to facilitate colour matching (they come in three light 'colours').

I also have one new (still in package) ceiling pendant for this type of lamp.

All the bulbs are branded: Osram, GE or Phillips and were expensive - they are a bit specialist and had to be bought from a trade electrical supplier.

I no longer need these, would appreciate a small contribution of some kind from whoever can use them.
