I have an older olight that I think would be pretty easy to switch components in. I have been interested in trying one of the MT-G2 leds, but I have absolutely no clue how to select a driver. I just don't have a good grasp on the finer points of driver/led matching. The light uses 3xcr123 or 2x18650 with an extension tube. If anyone could point me to an appropriate driver (preferably not very expensive) that will get good output with this emitter, with or without an explanation as to why it will work, I would greatly appreciate it.
