Convoy M21B Battle!
In this video, I compare the Convoy M21B host with two different emitters, the CULPM1.TG and CSLPM1.F1. Both of these emitters are very efficient throwers and produce an extraordinary amount of light considering they have a 2mm die surface. Is it worth putting up with the green emitter for some extra throw? Or should you buy the 6A / 8A version of this light? Watch this video to find out.
