Credit for this idea goes to Super x, when he mentioned looking for a flashlight that uses 18650 batteries I though what a great idea. I always have plenty of charged 18650 at the ready.
Did a few searches and wow the world of flashlights gets deep quickly and they have crazies ( I mean devoted aficionados) just like us, talking about all kinds of ways to mod them and the best to get. Prices can climb into the hundreds.
I found some very nice ones in the 50 to 100 range but decided I need to save money for the Woodvil sale, so I'll just go cheap and see if it's something to invest in later. I got this light for under $11 bucks and I'm amazed at how good it is, nice and bright good throw and beam spread, well worth the price.
