Hello, I am building my own scrubber similar in size to the L4. And ive got two question about the way you use LEDs. The L4 has a total of 16 Leds. Which ballast are you using, the meanwell LPC-35-700 ? Also about the wiring, I understand how you limited the power going to the blue Leds but then in the center, you go up to a junction block, why not just jump strait across to the next LEDs and make one string ?
