That's going to change those efficiency numbers. I'm sure with slowly increasing volume they will get cheaper and beocme the norm, but I odn't buy they are the panacea they are proclaiming.
One of the problems woth CFL's and especially LED's is try to squeeze the new technology into the same applications, LED's are smaller are more directional, they work much better as small lights spread out over the whole ceiling, than trying to squeeze them into a bulb shape that shines all around and screws into a central mount.
