help a 150g newb - let's do this reef together

[jon in alberta]

Thanks everyone for the tips. I really appreciate it.

I am just finishing off the plumbing and starting to think about lighting. I have to buy new stuff, and am 99% convinced I want to go with LED (I know they are expensive).

Here is the question: how many do I need? Specifically, I am looking at the Radion LEDs - what should I be thinking about? Does the watts/gallon apply with LEDs? ... advice please.
