I need to upgrade 2D cell Maglite to led

[xxo]

I've been checking the Firefly 2D, it's "factory rated" at 280 lumens but only throws 110 lumens with 2D by Adventure's testing. I keep wondering if that's worth the effort. The other Adventure options are for 3D and over.

110 lumens is a pretty good increase over the old 19 lumen krypton bulb, but you can always run your 2D on a 18650 or 26650 lithium ion cell in an adapter and use the 3-6 cell LED, that's what I do with my old 2D Mag.
