Whats the most powerful light for a 10 gal

[TJSlayer]

I have an incadescent hood with aluminum refectors and picked up 2 coralife 20 watt mini compact flourecent 50/50 bulbs.

10,000k/Actinic

Looks good and was only about $45 complete

May not be the best but works and provides 4 watts per gallon....
