I've been using an LED fixture on my reeftank for about 5 months now as part of a beta test, and I'm pretty impressed.
The same Co is working on a FW LED system.
Right now the issue seems to be obtaining penetration at greater depths, and not having the spotlight effect that the higher watt/power LEDs produce, but it's only a matter of time.
I'll tell ya, one cool thing about these is the lack of heat added to my tank, sure is nice running w/out a chiller.
