From personal experience, I declare the GE PL/AQ bulbs to be "yucky".

I had a 29g tank set up to raise some Rainbowfish fry and had some
Java Fern in there to keep them company.  The tank took a 24" bulb, so
I got a cheapie ($7) PL/AQ at the hardware store.  Hated it.  Blech
color and so dim I could hardly see anything in the tank (when you get
old, you need brighter light to see teeny fish).

After a week, I went to the LFS and got a PennPlax Ultra Tri-Lux to
replace it ($20).  It fit the scuzzy light fixture better (1.25" dia
vs 1.5" dia), made the colors leap out and allowed me to see the
little buggers.

Didn't she recommend something? Shame on her. Guess you can't offend
advertisers <g>.

. Triton
. PennPlax Ultra Tri-Lux 
     (only "Ultra", NOT "plain old" Tri-Lux)
. Coralife TriChromatics 
     (not quite as bright and DON'T get the reflector version)

These will do a fine job of rendering colors.  We're partial to a mix
of Triton and Ultra Tri-Lux.
