I did some browsing and it seems like your streamlight is a real home run. The "dual fuel" also is neat feature. I ended up purchasing one, $48 bucks shipped. Down the road maybe ill spring for a better one, but the features seem to be on par with the other lights I saw. Ive owned streamlight weapon lights before, they were solid.
Thank you, and thanks to the other people who chimed in.
A number of people who hang out here use the 1L-1AA, and I'm trying to recall someone ever posting a negative comment or experience about it. I can't. Along that line, it's also been in production just long enough to establish a proper reputation / record - so if there were issues, they'd be known. You didn't go wrong. Let us know what you think when you get it and do some test drives.
If you want to use ~3V rechargeables for the higher output, Surefire sells a pair of LFP 123 cells with a charger, as does K2.
Since you haven't spent too much money yet, if you find you'd like to find another light in this general category to pick up; as others have pointed out, there are other fine options. I think Surefire has some options in the 1XCR123A category, although perhaps not in the AA. Others 'round here are more familiar with SF than I am.
Malkoff does have options, and although a small(er) operation, their reputation is impeccable.
The same is true of Elzetta, and I also personally use their Alpha-Gen3 and love it.
From everything I read around here, I don't think you could go wrong with anything from either of those two companies. They are also both small(er) operations with great reputations, and I believe they both still manage to do all of their production work domestically, which is also a 'plus' in my book when I can get it. Some of my SL lights purchased in recent times are also 'assembled in U.S.A.' as well (Polytac X, Stinger 2020, etc.), and although not all of their models are (like the 1L-1AA), SL is
very much a U.S. company (since 1973).
BTW: I also use the 1L-1AA's slightly larger 18650 sibling, the 2L-X. It shares much with the former design, and I also like it a lot. Being essentially a slightly larger 1L-1AA for 18650s, if you like one, you'd like the other; they share the same features and operating characteristics.
