Makes no sense to have anything like the same output in a church hall.

You've been there and assessed it then? Odd, given I've not said anything
really about it. Perhaps you think they are all identical.

Don’t need to. There is no church hall that needs anything
like that level of output in the individual lights.

Seems quite reasonable:
say 30m x 10m = 300 m^2
allowing for using light reflected off ceiling say 1000 lumen per m^2 to
give 200-500 lumen per m^2 on the floor.
= 300,000 lumen ~~ 10 x 20,000 lumen fittings
Right ballpark and as the OP says current light levels are correct for
the diverse range of activities in the hall.
