+1 to what Steve said above. That info from Coral Sky may be slightly biased as they are obviously marketing a product without optics. As Steve said the cost of the optics is small and they help with concentrating the light so you get better PAR deeper in the tank.

As for the patent, I think all it needs is to be challenged in court and invalidated. I can't see how that patent was issued as they found nothing new or revolutionary or surprising that merits patentability. There was also a bunch of prior art that the patent examiners obviously didn't see. PFO was in financial difficulty before Orbitec went after them so they obviously didn't have the finances to fight it out in court. Hopefully somebody can do that at some point.
