    D cell = 16AH. Yes *16*
    AA cell = 2AH. 1 D cell = 8 AA's!
    AAA cell = 1AH.

    Keep in mind that is at 1.5v, so if comparing against a lipo powered light, the lipo runs around 3.7v, or 2.4X more power per mAH.
    I have a 3 D cell LED flashlight, circa 2001. It uses 20 (5mm) leds at around 20ma. I left it in the attic once, and it was still shining a week later when I figured out where I'd left it.

    Of course, that 2 pound flashlight would be a bit much for a headlamp.

            I would recommend looking at headlamps that use CR123 batteries instead. Yes, they cost a little more(they are cheaper online) but they run brighter and last longer.

              Dt
              CR123 Typical capacity: 1500mAH (lithium non rechargable), 700mAH (Li–ion rechargeable)
              Note thats at 3v and 3.5v respectively, so a CR123 gives 4.5WH while a AA gives 3WH, Not exactly a huge improvement
              Checking on ebay I see lithium CR123's for $2.50 each while AA's iv bought locally for $0.30 each on a good deal, but 0.50 each is pretty common if you find a bargin store.

              That said, you can likely get more peak current out of a CR123, but then I bet a D cell would still kick its ass given D cells are *16* AH for $1~ each.

                Button cells?? I'll pass on that.

                Agreed!. A D cell headlamp would be kick ^ss for burn time, but a little heavy for a headlamp unless you revert to the old miners style that used 4 D cell in a belt battery pack.
