Pickup, how does one determine how many leds to use on tank? What colors? Etc..
Yikes... that is a major discussion... take a baby step by getting one of those stunner strips first... that will go a LONG way. a Full LED system will cost you a couple hundred bucks or more to get there.
Bart's tank is pretty awesome. a 185 with two 400 watt Halides at 12k with no other supplementation.
