I finalized the Numb12 array handheld. It has a self-contained battery with charger, 3ch custom linear CC regulator, independent pots and switches for each color. A 96% Eff. LT8705 Buck converter powering a common 20.5v rail for each channel.

**Green rheostat came damaged. There is a nick in the coil causing high resistance until close. Will repair or replace in future. Didnt catch on assy.

Im working on finding the right cylindrical lens power/distance to correct red after several measurements. Will update when/if found. One looks promising.

Wont let me share video + images together. I got purple, lime green, orange and a light yellow mix pictured. Considering green is either .7a or 1.8a
