I don't know when they upgraded it... probably installed a more efficient, more modern emitter.
I have an incan AA maglite, the AA LED maglite, and AAA maglite LED. If anything, the newer ones are too much. It'd be nice to have a low mode, which I understand the "Pro" models of these may have. I could look it up, biut it doesn't matter as I have them mostly as modern upgrades for my dad's old flashlight, for nostalgia.
If nothing else, they are durable!
