I visited a freind in a Retirement Home on Tues. All looking very homely except for a few bare CFLs in his hallway.
I noticed the lampholder was something I hadn't see before so I didn't offer to go back to fit some lampshades without doing a bit of research.
It seems the lampholder only accepts a special CFL (I guess the control gear is in the lampholder).
What are the issues around fitting a lampshade - I am guessing a conventional one with a ring will be too small. I think there were 3 lugs around the lampholder.
