The T50 is a nice little torch, much more user friendly than the T67, turbo mode? having not seen a Ludicrous Lumens pill , a couple of ways of doing this is firstly fitting a highend binn xpe-e2 led to improve performance and secondly fitting a 1.4 amp driver instead of the usual 1 amp one to overdrive it. Only downside the 1.4 will generate more heat. Only other suggestion, is the lens, fitting a better quality one will improve the die size and quality, this is were the Nightmaster has the edge over the T50.,but for the price the T50 is cracking little unit. Panasonics 3.4 amp/hr 18650 batteries probably best out there.....P.S Noctigon copper pcbs probably best to use for Cree xpe leds
