I think 16+16 would be best so the brightness is more even. Wouldn’t 18+18 make the brightness less even without increasing the overall brightness by much?
Do you need jumpers? Wouldn’t something like this work where the red highlight is the (+) and the black is the Warm white Negative and the blue is the Cool White Negative work?
do not worry, all will be fine. I use 660nm (for growing lighting) since 2014, and I see difference by my eyes between 630 and 660nm without spectrometer.
Also I am going to order it from another seller too
I asked Barry from sofirn about making an LT1 “Host” (everything except for LEDs and mcpcb) available but sofirn seems to not accommodate such changes unless they can expect 50-100 orders.
