Just a minor nit: Power compacts do put out slightly more LPW than regular
fluorescents, but not twice as much.  The literature I have shows Power
Compacts' efficiency as similar to T-8's.  Maybe 50% more efficient in LPW
than old 40W fluorescent bulbs. And the older 9W and 13W compact
fluorescents are same efficiency as old fluorescents.
