I have been discussing with a manufacturer in China about a two channel 384 lm561c led panel 4" x 12". Each channel is 50w for 100w board capacity. Various meanwell constant current drivers work. Very flexible in opetation. The manufacturer wants $800 for 13 boards, but I do not need that many boards and thought about sharing. If anyone is interested in a CO-OP just send me a pm. The cost is $60/board plus shipping. No money in my pocket.
