I just got my first Full Spectrum bulb (GE Chroma 50) in the
bright orange cover (I forget the marketing name). I can't tell
the difference between that and a cool daylight bulb by looking
at the light. In another month or so, I can tell you if these
Chroma 50 bulbs make a planted tank grow better than cool daylight.

I'd be very disappointed if I don't get better results than
with a cool daylight bulb since it costs almost 3X. ($6.50
for a 2ft bulb).
