Yes, unfortunate that even Philips neglects to mention the LED wavelengths. There aren't that many LED colors available, all of the manufacturers have the same color set. So when the Philips literature says blue they mean about 460 nm (Cree has some at about 450 nm that they call Royal Blue), deep red will be about 660 nm and far red about 740 nm.
These LEDs are the standard color set:

Thanks again for the links.

A couple guys in my aquarium club have/are building their own fixtures so they can pick the specific LED's and wavelengths they want with Cree's being the LED of choice. I'm really hoping to not have to go down that road as I am no electrician by any stretch and most of whaty is currently commercially available for non-aquarium use has a fairly small footprint.

So, the search continues...

Cheers.
