With half the lumens wasted.

In many cases perhaps, but not really here - the location needed direct
output from around 300 degrees of the diameter of tube, rather than just
down at the floor.

You can get LED tubes with a 300 degree spread eg
https://www.tlc-direct.co.uk/Products/LTT524W.html

The ones I usually fit (as a retro tube fit not a new fitting) have a
140 deg spread.

And it is, as you know, horses for courses. It's nice to see someone
actually think about what they want/need with their lighting.

But I would still try to sell you LED:-)
