Two of my favorite lights, a Convoy S12 with 219Bs, sk45 4500K, and a mule I built with a S16, a 20mm 2S2P 219B sk45 4500K MCPCB and a 6V 3A buck driver. Yes it's deep for a mule, but it gives it direction and mass for heat. Both have great beams. I have my S12 on a tripod and clamp on my desk and use it for soldering, technical work, and photography. I do miss this bin, but 5000K is quite nice too.

Very nice.
I can’t believe how nice the 519a is for soldering. I always hated all my work lights and desk lights, after finding this sub I learned why
I want to try the S21F because I life to change the temp during night or day. And I want to get a couple 3x21E with 2700 and 5000 519a for electronics and photography stuff
