Some prefer the old one and some the new one. The light was marketed as a 2000 lumen flashlight and it could not reach that claim, i guess thats why they offer the new version now which should be a bit brighter but has less throw since it is the “Hi” Version + it comes with the IMR cell. All those steps should make it brighter, i dont know if it can reach 2000 in the end. Im sure many ppl will test that for sure. I would prefer maybe the new version because i dont care that much about throw
