Not sure who the OEM is of this version of the light. Also not sure if the newer updated version is same OEM or not. Based on customer feedback from Vinh’s Tange 1, this version of the light is pretty horrendous, but the newer, updated version is really durable. My own Tange v1 also died on me. The newer version looks interesting, but I’m getting the JetUSolis to satisfy my small EDC high cri needs.
