Hey guys, just got my K7 v3's and just wanted to share that I am very impressed with what you get for the price. Setup was a breeze, App connected via LAN no problem, and programing over the app feels good. These things are BRIGHT! I think two modules will work great for my 3x2 feet tank, and I will try to get my hands on a PAR meter. If I get 2-4 years out of these units, I will be very happy considering the equivalent wattage for Radion's would have set me back about 2 grand and I got these for less than $400! Took a quick video of my freshly cycled tank. I'm not sure how to get accurate color on my iphone, so the blues look over saturated in the video. I actually like a more white look, and I have it around a 14k color temp. Don't hesitate to consider these lights!
