The solar eclipse 4 and 6 cob lights use lsd drivers I believe. Comparable to the meanwell. Cree3070 cobs and Cree xp-g2, xp-e leds
The pro series use meanwell. Pro 4's have 4 meanwell drivers in each. Cree 3590, xp-G3 and xp-e2 leds surrounding. They are the latest release from Cree. Copper core heatsinks, my favorite is the 2 switches. The rings are ideal for vegging and are lower intensity. Then the cobs kick on and it's just nuts. 93cri which I think it the highest of any manufactured grow light out.
