Flashlight Comparison Review: Convoy S21B (CSLPM1.TG) vs Convoy M21B (CULPM1.TG)

In this comparison video, I compare the Convoy M21B with the S21B. Both have PM1 emitters, the main difference is the size of the host. Let's see if the smaller host of the S21B can keep up!

I thought this would be an interesting comparison video, given both lights produce a similar amount of lumens and also feature 3 x XHP70.2 emitters. Heat dissipation/battery life is far superior in the Wuben X-1. But the MS03 is smaller, lighter, and easier to carry around. Find out which one you should get by watching my video.
