For some added LED info, I just did some PAR readings in the iReef pico. it has 6 Cree XR-E LEDs being underdriven by a 350mA dimming buckpuck that I actually have turned down a little from full power. No optics are used, just bare emitters. PAR readings were about 170 near the top of my rock which is about 4 inches below the surface of the water and about 5 inches below the LEDs. Par drops to about 80 near the bottom of the tank about 10 inches below the water line.

A bit slow as I need to redo a few of the molex connectors and pick up a few little bits for assembly. But I did a quick test in air again with optics. At 18" with 60 degree optics the PAR jumps to about 375 vs 250 without optics.
