The Preon P1 is such a neat light, but it is only 100 lumens. Skylumen sells the PreonVN, but $125 is a pretty premium price. I can get roughly the same parts that Vinh uses from MTN electronics for less than $25. How difficult would it be to basically do the exact same modification that Skylumen does, but on my own? I am pretty competent with modding lights, but I have no idea if I need any parts such as custom spacers, copper heatsinks, etc.
