Karin, don't get me wrong. I totally agree with you that the controllability of the led's make them totally awesome. There's just too much data that points to the superiority of led technology. BTW, those were some really nice pics you posted!!!

But, for me it comes down to just being old fashioned. It's like the houses at christmas that are lit by led christmas lights vs those with old incandescent lights. There's just a different "feel" to the led's that seems cold. Or, the fact that I prefer listening to some music on vinyl vs electronic format.

Who knows, after I get the led's setup for my wife's tank, I might just convert and dump the halides on my tank.
