I spoke to Chris at coralvue about this fixture. It will be available in the 4th week of January 2013 in the US. So like february in all likelihood.
I spoke to Jeremy at premium aquatics about this light as well and he told me that it throws a fairly narrow beam when mounted on the tank. It was designed to provide high lighting for reef applications and it seems like the 8,000k was an afterthought. Had they designed this light specifically for planted tanks I believe they would have used wider lenses. Spectrum looks great though and should be a nice addition to planted tank lighting options.
