3xAAA flashlights are quite common. So lets say your Lithium Ion cell failed, you were unable to charge it for whatever reason, and you lost your spare. If someone in your group has a spare 3xAAA set, or you head into town and a cheap 3xAAA light is on the shelf — you’ve got a substitute.
The entire concept for this light originally was a small, backpacking oriented version of the LT1. If size isn’t a concern, use the LT1. The LT1 already has all the things you are looking for when size isn’t a factor. Heck, with a little ingenuity you could probably shoehorn a 3 AAA carrier into a LT1 if you wanted to. Where size is a factor though (the whole purpose of a mini version!?) the 26650 is unwelcome.
I wouldn’t take AAA’s as an emergency, I would buy them anywhere, unlike lithium ion cells (of course I’d have several other lights with me as a backup too )
This LT1M was intended to be more compact, (thinner) to better fill the need for campers, backers, canoeists, Kayakers, etc. The 26650 is an older format, & loosing popularity in favor of the newer 21700 thinner format. A base cap will likely be available for better stability.
It would have been good to PM the waiting list about the poll?
Been waiting for LT1 mini for so long I don’t check the thread much and missed out on the poll, luckily for me the smaller option was selected because as dbsar says a few posts above I thought the intention was smaller and lighter for use where weight is a consideration.
As many have already said, if weight is not a consideration just take the LT1.
AA compatibility of no concern for me a in a light like this.
