we have a idea for ours QP276 full spectrum led boards, it is acutally assembly with 3000/4000K chips and 660nm and 385nm chips, the 385nm chips with a switch .
but now, there is a idea, we want to change a 660nm with 730nm chip, and also , put a switch for 730nm, then there are 2 switches on the board, one for 385nm, one for 730nm chip, what's your idea?
