Decent fixture, I use it on my 30 gallon, and yes, these are normal output T5s. On my 16" deep tank, I can grow anything I want (depending on my CO2 dosing).
If you're only issue is the yellow color, why not upgrade bulbs? GE's 9325K bulbs get great reviews.
Sweet im working with a 46gl bowfront and thats about the same depth. I think ill jump on this one. Like I said its only semi planted I have a small 10gl im going fully planted with to start getting into this plant stuff. Like I said for the 46gl im just looking for to not have yellow lights and to be able to grom a few easy lowlight plants. So thanks for the input everyone! This thread has helped me learn alot about plant lighting.
