Regarding the "screw in" type fluorescent these do not have the same rated
lumens per watt as tube or CF setups.  I think that this is largely because
the base contains what is probably a cheap ballast that is pretty
inefficient.  Therefor a 30 watt "screw in" might actually be a 24 watt,
say, with 6 getting lost in the transformer.  Since CF and tube are rated
downstream from the ballast this doesn't count when calculating watts per
gallon.

I was thinking, though, that used with the old duel screw in type of hood
that these would be great for a mini/Amano type setup for 10 or 15 gallon
tanks.
