Anyone using Par 38 LED's on their tanks?

I ran 4 par38's from Paul @ oceanic Corals over a 6 foot reef for awhile and was generally pleased with them illumination wise. Only problem was the coral growth butter zone was fairly small so all my corals were grouped in clusters under each light. On a fowlr it would be fine. Look for a wide optic (60 or 80 degrees) to minimize shadows or just hang them higher.
