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.

Thanks for the info.  So how many and what kelvin would you use for a
water depth of about 18"?  2,3 or 4, and 5500k, or 6700k?
