that's a good c3-type 18650 host, but adding driver and LED, the price will be way over the $14 UF-2100 or HD2011 or similar lights. Anyone know of a similar light where I can scavenge the pill/reflector/LED(xpg)/driver(0.8v-4.2v) combo so I can just pop it into a MatchMod mini maglite without hunting for a 25/32 drill bit? Yes, the pill/reflector/LED(xpg)/driver(0.8v-4.2v) combo that fits a mini maglite is a tall order... the search goes on.
edit: nevermind, UF-2100 price dropped to $10.
