Little Janky Pinky
Convoy S21A with P2500 buck driver and KD full spectrum pink 10W 5050 emitter.
Fun little light, but a little off in that the Vf of the emitter is 4V on high but it didn’t play well with the convoy buck/boost driver…. So I went with a buck. Use 2x 18350 to get well regulated performance or 1x 21700 for convenience and runtime but experience voltage sag.
Either way it’s a fun light that throws well for an S21A.

Cool combo. This would be a great gift for someone whom loves pink.
Thanks for sharing this! Pink is underrated. I have a pink S21 sitting around not doing much (SST40 inside) that I see needs to be worked on.
It’s a pretty easy swap, especially when you aren’t worried about voltage sag.
