We just finished working on one that uses meanwells with 0-10v dimming for the Apex, Reef Angel, and other controllers. The upgrade brings the price up $99, to $299 shipped, which is still $100 less than the competitors! And, if you purchase the dimming upgrade, you can add 90 degree optics at half price! We can also add this to the cree fixtures, let us know what you guys think!
