I have 
They seem to be the same tech as my quantum board 120’s just in strip form…now hlg has moved on. The boards are amazing…flowered a Laughing Buddha over the winter with 4 of them for 240w in a 3x3x8 cabinet- she grew into a 4’ tree with nice fat dense cola’s. Blue cheese did equally as well with 3 of them for 180w in a 2x3x4 cabinet…filled the whole thing lol
I do have a limited budget though I can buy drivers or a cmh conversion kit one month then the lamp or boards the next month. If I do quantum boards in the 3x3x8 cabinet (have 2 of them) then I would like to do 6 for 360w this time around though the diy is only available in 4 packs now so the cmh is looking the way to go though by the time I am ready to gear up, there will probably be something new to try lol
