Im sure George could set us up with an excellent driver, but then we would quickly run into problems with heat sinking unless a much larger deeply finned one could be made.
Its hard to beat the bang for the buck when considering the super easy Trustfire X7 MTG2 mod. The large stock reflector takes advantage of the MTG2 and casts a fantastic beam. It would have been nice if it came equipped with a 26650 or 32650 battery tube, but it already does well on its own with 3 x 18650’s.
