Three Convoy lights with 8A buck drivers for getting the most runtime out of 21700 size batteries. Purchased for $28-$38 each with batteries included I think these are an incredible value.

S21D with four 519A 2700k emitters and 60 degree beaded TIR:

    Great choices! I didn’t realize you could get that driver in the S21B.

    I love the 8A buck drivers. Now that they have a 17mm 8A driver I plan to make an S2+ triple.

      I would highly recommend it! I just upgraded my s2+ triple with this driver and a Kaidomain 519a DD 3500k. It’s a wonderful thing.

      Thanks! Since the S21B supports 22mm drivers (unlike the S21A’s 20mm) it has a few more options, although this config was by request in the order notes.

      As for 8A buck drivers, nowadays they are available in 17mm (as you mentioned) 22mm, and 20mm as well which I’m hoping to try (maybe mao S21A with sft40?)
