Zoomed's plant bulbs, the Aquawave red are also quite good and cheaper than the other brands. Good Aquaflora replacements. The GE starcoats are better replacements for the midday's also.
I got 50% more light from the ATI vs the old TEK lights, but the fixture cost 2x as much.
But I think the color of the bulbs plays a big role, you can mix and match, cost a fair amount to do this, but the results are very good.
