Hmmmm, not much better in my opinion than the 9325 K, though I'm pretty sure this is the next bulb I would try for my setup...

It seems whenever I look at the curve for a bulb and compare it to the one in the article given on this topic, that the red peak could be at a higher wavelength (I was surprised to see this on this bulb since it has a separate red tube), but if I see correctly, the blue is pretty good on this bulb...

Lots of green output though on this bulb, thats the problem. If the bulb is going to be white, you need only red, blue, and green light to make white, so that explains why green is a high peak in so many bulbs. What does everyone else think?


Tank in transition! 55 gallons, hard water.
