I will answer you but first I'm asking you since you made the statement stay FAR away from and said that the hlg are the same as the alibaba boards. I can assure you they aren't but with such a strong statement I would think you have a good understanding of the components and differences. So again I'm asking what the difference you are claiming is.
Already stated it.. same boards, same diodes, same driver.. what else is there that can differ? basically same umols too. but for half the price, thats why stay far away from hlg.
