You know you can run the whites and the blues at the same time, right? It doesn't have to be one mode or the other. I've found that when both are on together it runs a blue-er color than most light fixtures. The corals look great.

Not sure, there are multiple manufactures. The ones I imported used a little cheap controller box and were computer programmable. The Tautronics unit I tested was almost identical in PAR and even design to the ones I use. I think these have a small knob that dims the white side and another one for the blue side. As long as the wattage lines up and the lenses are right for the coverage you want, they will probably be okay.

On a side note, I am finding that even with Acros, we are using too much LED light. I finally bought a PAR meter and my findings will be published this weekend, but I was surprised.

Can't wait for this report. mr_x did a par report too and i'm curious to see how yours compares. I know for sure that my acro needs to be moved down away from the light some.

I shipped one to him to test and I think he found it to be almost if not the same. I will be running my own independent tests as I am using one of the new dense LED chips for a light I am building.

Just about. I started with it several feet above the water surface and lowered it over several weeks to about 10" over the water.
