Rather than speculate on that further here, this thread may more usefully address other modding options.
Without knowing more specifics of your needs, it is difficult to advise. In terms of offering a very broad range of modding services and significant technical ability, you may wish to look further into the V54 subforum, as well.
thanks archimedes, sorry got sidetracked about Pflexpro. Id like something in lightweight 25mm straight-sided( or however to say head same size as body) protected 18650 based, remote pressure switch compatible, recoil proof(low recoil only, not shotgun), weight around 3oz, 1000-1500 lumens, a reflector to get 22 KCD lux , no fancy functions needed, this light will spend its whole life being turned on at 100% and off again. Lastly, a fraction of surefire price. At the moment considering one of the off the shelf higher power Convoy S2+ 'osram'(?) if nothing else suits. But would be prepared to pay 100 USD or so.
