I don't know where to find GE Chromas, but I have used some of the Sylvania
bulbs with good results. The Gro-Lux is a very "blue" plant bulb that brings
out fish colors well and does good on the plants too. Right now I am using
Sylvania Sun-Stick bulbs (along with Tritons and Corallife trichromatics). I
have been getting really strong steams of oxygen bubbles coming off my
plants, so I tried turning off each different kind of bulb to see if I could
tell which ones were most responsible for the photosyntheis. From what I
could tell (this was not by any means a well controlled experiment), the Sun
Sticks were doing more than the others for oxygen production and therefore
for plant growth. However, it may have just been related to bulb location
over the plants, bulb age, or any number of other factors. Still, I like the
Sylvania bulbs, and for the price, I think they are worth consideration.
