I spent around $1400 on his setup I use over a 6x10 area.
The prices I paid for meijiu board from alibaba at the time were slightly less than HLGv1 boards cost right now. (around $24 per board IIRC)
You want at least 30w per square foot. I would not attempt to light the whole 10x15 unless you can afford to put a minimum of 4500w over it.
At 140w each for the V1 boards, youd need at least 32 of them at $30 a piece. Plus heatsinks drivers frames ect.Another example would be the HLG kits. You need 17 260w kits at $350 each. A 260w china kit is just a little over $100 now.
