I just got two of the PAR38 (3white/2blue) lights for my 60gal after talking to one of the guys over there. I need to buy 2 more, but even with just 2 its substatially brighter than the coralife PC fixture they replaced. Cost was only $250, the bulbs are $120 ea. and you can get a basic 13' cord with a light socket at the end of it from Ikea for $5ea. The lenses on these guys gets more PAR for your buck just like the reflectors with the stunners. Shimmer in the tank looks awesome, now I just need to start buying corals.
