I'm using the SeaLights power compacts quite successfully on a reef tank.
Under the day bulb 27W 6700K, an acropora has put on 1/2" growth in a
month. I cannot fathom any plant species having more light requirement
than the reef critters, so I can say that the output is great.
Now, let's talk cost. I've got $110 for a 20g tank. I would say that the
light requirements scale linearly, thought the cost dosn't due to
different bulb types. However, if you're going for ultimate bulb output,
you're going to need to replace things things yearly.
I'd strongly recommend just getting 2-3 175W MH fixtures with the 5500K
bulbs. The DIY kits with the 5500K bulbs can be had for $125 (shipping
included). The bulbs don't need replaced nearly as often , and the
replacement cost will still be far less than the compact flourescents.
