I would like a modern circular but the choice is almost nil. One that I
saw in a National Trust Cafe was this - with a T5 tube. But alas too
costly to have two of them:

That looks really nice. How much?

I've wondered why circular tube fittings all seem to look like this:

It's *so* 1960's.

A cautionary note, that the 32W, 40W and 60W T9-T12 circular
fluorescents are below the minimum efficiency level that the
EU intends to permit to be sold in a few years time, so you
should expect their sale to be banned. These were all old
halophospate tubes, although the ones you buy today might be
triphosphor (I've not looked), but will still be lower
efficiency due to the tube geometry.

There are some new efficient T5 circular tubes, but they aren't
retrofits for the old fittings - they must use electronic
control gear (like all the new T5 tubes), so the old fittings
will be useless unless you get a stock of old tubes (and their
filament lamp ballasts if you have real 1960's ones;-).

Thanks for the tip-off.
I bought the 32W version from Argos. It is a good light but is heavy so I
assume old-fashioned gear.
It's re-packed to be returned; it kept cutting out due to weight on the
batten holder and buzzed occasionally. The diagram shows it in a pendant
fitting - on your own head be it!
