Lumens per watt from an LED is in the same range as a halogen. The range I've seen quoted for halogen is 14-20 lumens per watt, and if you look at the LED's on that page they are all around that.
The difference is the halogens are most efficient around 20 W or so, and LED's are most efficient at less than a watt. If you want a 20watt light, go halogen. If you want a 1 watt light, go LED.
I've thought about getting one of the LED MR-16's for use as a super-long-runtime option, but I'm deterred by the $30 price tag.
