Since I wrote that yesterday, something nagged in my mind. Since I have a
low voltage 20 watt halogen and a CFL (which turned out to be 18 watt) in
locations where I could easily measure the light output, I did just that.
Maybe I shouldn't have been surprised, but (correcting for the difference
in
rated power) the 20 watt halogen was a little brighter, than the CFL (but
not by anything that you would be likely to notice). The 20 watt halogen
spare in my cupboard is marked as 'energy efficiency E', and the dimmer
CFL
is marked as 'energy efficiency B'.

Something is very very wrong here.

spotlight vs floodlight. Easy mistake to make I guess.
