Looks like AI is built similar to that. For my larger build I am using a Switching Power Supply 200w, 25V @ 8.3A from Stevesleds. With that one I am using 7 XT-E LEDs per string just fine. You can find many like it on ebay as well. This is pretty much what Ecotech uses. The beauty of these drivers is that they dim to 0 and cost under $5 each.
Awesome.

Ok help me out here so I can understand better. I am trying to mimic 2 of the new ecotechs with around 84 leds over my 120 gallon.

Could I get a 350w 48v 7.3a power supply and 7 of these 48v version drivers? How would I hook them all up to the power supply, and how would I make 4 dimmable channels out of it connected to an arduino like Typhon Boostled, or 7 channels with two arduinos?

Can I also mix and match different current drivers, like the 600 mah version along with the 1000H?
