I have all kinds of mag lites, have lost a couple to leaking battery
I use flash lights every day, was carrying the AA mag lite, then
went to Pelican, with the 3v batteries. They are expensive and
don't last. Then I found a rechargeable Stream Light laying on
a post at a rest stop. I didn't have a charger so I offered to give
it to a LEO. After bawling me out for being cheap, he told me to
buy a charger for it. He even ordered it for me from aPolice supply, $30. 110v AC with a 12v DC adapter. That was over 5
years ago, use it every day. It puts a 3 cell mag lite to shame.
I think a new one is $100+. I would have never spent that much
on a flash lite, but if something happens to this one, I wouldn't
hesitate to buy another. You will get it back in battery cost. I
guess if you don't use one in your everyday work, it may not pay
you to put that much in a lite.
