GE Sunlight (Chroma 50) vs. Plant and aquarium (PL-AQ) fluorescent tubes

"better" is suubjectibe depending on your needs. In general,
if you're using one tube, use the Chroma 50. If you're
using two, use one of each. The PL-AQ has lots of red
which is the C-50's only fault - an excess of blue.

If the GR Sunlight bulb isn't a Chroma 50, don't sweat it,
while they're better, it's not worth killing yourself to
find them. There are three tubes you'll find from GE that
fall into the daylight/sunlight category:

F40D - Daylight. I think this has been discontnued, but is 
probably still around. Not a whole lot better than Cool Whites.

SPX65 - Sold as "super daylight". Better.

Chroma 50 - A drop in replacement for Duro Test Vita lights
at almost a tenth the cost.
