I've got two A150 10K's running on my 29 gal planted. Great looking light, nice bluish color, and fantastic plant growth (Yes I'm fully aware this is a reef forum). My only complaint is the lighting coverage for the power and price of the lamp. Perhaps it's best feature is I found out they're water resistant. It fell off the hanger into full submersion for 15 min. Dried it off, plugged it in, still works 1 year later.
