For some numbers, I have the LED's about 6" off the surface of the water the top of my rock work or the tips of the green acro on the left are getting about 325 PAR, the Rastas also to the left are 250 ish, and the sanded varies from 80 to 100. These values are straight from the clubs apogee PAR meter. I have set the Apex to ramp up the blue channel to 75%, and the white to 50% over about an hour, then it stays there for 8 hours and ramps back down over about 2 hours.
I have only had the lights in operation about 10 days, and I have a few immediate observations. The Jason Fox Witch Hunter monti LOVES these lights, I think I can see it growing in front of my very eyes. The algae that grows on the glass has been reduced by 80%, most likely due to the light being so focused down onto the rock work. My black background also seems to have faded into the back even more, I am sure also due to the focused light no longer illuminating the glass panes themselves.
I'll make sure to update the thread as my tank grows, I added several new frags this weekend from a local swap, and so far everything is HAPPY!
