A fluorescent tube with electronic "choke" is as efficient as an LED bulb.

Not any more.
If you take into account losses in the fluorescent luminare (getting the
light from the wrong side of the tube to where you want it, or losing it),
they never were.

But isn't that often part of the whole 'lighting' process, especially
in a domestic environment, having light shining in all directions
(especially reflecting off the fitting / ceiling) and giving a much
more overall (albeit less efficient) illumination to that space?

Working in a room with a single central light reminds me how nice it
is to have a 'long' light source, when you start to try to work with a
single point and are often in your own shadow. ;-(

Are you aware of any 6' LED fittings that offer the same light level
and colour temp as the two TL-D 70W 840's I have now?

That's not even considering the chances of recovering the cost over
the years I have left. ;-(
