Update time! I reinstalled the hanging wires at a shorter distance, and raised the fixture a few inches. I also reduced the current a bit. It seems I was getting much more light from this than I originally calculated. It has warmed up quite nicely. Even at the greater height, there is very little glare with the optics installed. It makes it very pleasant to view my aquarium. Absolutely loving this, and so are my plants. No trouble getting color from my Rotala, and everything looks super healthy!
Btw, six bridgelux blues are too much for moonlights. I have to keep them cranked WAY down. Almost no use at this level. Might replace them with some warm whites to bring out the reds and oranges a bit.
