Just curious on who else runs these lights or the other variations they offer. So far my experience has been excellent. It out performs any other light I have run. These run 6 inches above canopy and very cool. It's a true 4x4 light and the adjustable blades are amazing. You can tilt the individual lights on axis. I also added in a 4 foot uv setup onto them. I got 4 lights tucked in. I run two of these currently and will be getting a 3rd next month for veg room. Right now I'm using my old leds in veg. I use a platinum p600 and a t5 setup for my seedlings and clones.
