I just got mine in on Friday. Up and running the last half of yesterday. I went from 3 Viparspectra, 2 T5s, and 2 Royal blue led strips to 3 of these units plus the LED strips. Tank size is a standard 180. I Love the spread on these, but the color is a bit of an adjustment. Not bad at all, but definitely more natural coloration and not the cartoonish saturation I’ve gotten used to with the Vipars or Radions. Max par at 100blue/100white is roughly 12k, visually. Reminds me of an unsupplemented Ushio 14k (without the shimmer) I do wish there were a couple of deep red leds along with the amber, but I get what they’re going for with the natural look. My diy led strips add back a good bit of that pop, so now I need to tweak the color profile settings and intensity to what looks best for me. The app could not be any easier to use or connect.
