If you look carefully, some operate degraded with .3af power. I've not benchmarked many of these so I can't say exactly what they get. I am wrapping up another Tech Note on some recent testing, though, and I'll post something on that in my blog (http://www.nww.com/community/mathias) shortly. You can see my earlier note on this subject here: http://www.networkworld.com/community/node/25449.

Thx. Craig.
