Hagens are a bit pricey. Attached are the graphs for the PowerGlo, LifeGlo and AquaGlo. The AquaGlo is probably the better plant bulb. It is somewhat like the GroLux but lower power. I also attached two graphs of normalized spectral plots so that you can see the output intensity at a given nanometer in true relation to each other. You can go to HomeDepot and get some T5 Philips 6500K that will balance out the lighting and make it more pleasing to the eye.
