I received a TS30S from Wurkkos this week, ordered without batteries so I could use separately purchased Molicel P42A’s. Because of a mistake in the ordering process from another company, I received a second TS30S for free which included a Wurkkos battery So I have a unique chance to compare how beamshots look side-by-side for the same light, with two different batteries.
This link shows the beamshots (sorry can’t figure out how to paste images into post directly): iCloud
The first image is with P42As in both flashlights - the beams look pretty identical. The second image has a P42A in the light on the left, and the Wurkkos in the light on the right. That image shows what I see in person, the left beam is noticeably brighter.
