Agreed with assessment above from other BLF’ers.
I spent much effort trying different batteries and AR lenses to squeeze the highest output and furthest throw from this Wurkkos TS30S, one of my most favorites in my collection. And then spent hours measuring and documenting changes. I did it because it was fun and educational. The results are above for your interest.
But for actual use, IMHO Wurkkos battery, despite of its lowest output, is more than good enough. The main reason is step-down. A higher output just results in faster step-down. And the steady state output of all small lights like these are temperature-management dependent, not battery output dependent. P45B is my go-to battery at this point, but not for 14 euros.
