Larry, thanks for that info. I perused Sanjay's site a while back and all I got out of it was a headache at the time.
I got the bulbs cheap, and everything that I had read about them was good, everyone who had them loved them, stating that the 12000K bulbs provided basically what I'm after - It's in the lower K
range providing for better coral growth, but didn't exhibit the visual aesthetics of being in that range. I run 10000K bulbs on my FW
tanks, and for this tank I really wanted something with more blue in it, while still providing for good coral growth.
I got a pair of bulbs, used less than a week, for $50 shipped. I figured for $25/bulb it was worth a shot.
