i have a single cell (aa) light,, Nextorch is the name on it,,,got it off a clearance rack at GameMasters,,,,bout 60-80 lummes i guess,,,dont remember what the package said,,,pretty bright,,,has a high,,low,,and strobe,,,also can connect to computer and change how it works,,,i have it so first on is high,,,it is also a regulated light,,,so when it starts to dim,,,it only goes so far and you need a bat change
i picked this thing up on a close out rack for $7,,,i have had it for about 3 years,,,i never thought much about it when i was younger but i got to say i use this little light all the time,,,kinda like my carry gun,,,i feel naked without it
when you pick,,,,and there are lots to pick from,,,get a good one and you wont be sorry,,,dont look past the expensive ones,,,,BUT,,,dont get caught up in that either,,,,there are lots of good lights out there for not lots of money
you might try Battery Junction,,they have lots of lights,,,,,keep your eyes peeled,,,you might stumble onto a jem somewhere you least expect it
