It aint that bad, OSRAM have started to do direct halogen replacements
for GLS bulbs, Sainsburys sell them. They consist of a halogen capsule
lamp inside a secondary bulb with a BC or ES cap. They take a little
less power, 42W for the same output as a 60W.

They aren't the same light output (and don't claim to be).
Neither do they meet the proposed EU requirements on efficiency
to survive the EU ban.
