Need many flashes with my Nikon SB 600

    I need to take, perhaps 1200 flashes over several days for time lapse
    photography
    using a Nikon SB 600. Is there a 110v adapter for it?

    how about Lithium-Ion AA batteries? These are pricey, about $2
    maybe more each, but I tried them on the recommendation of my fav
    camera store manager in my Canon 430EX external. True to the
    store's claim, I get at least 800, sometimes 1,000-1,200 flashes
    per set of 4 batteries and my flashes are more consistent than
    before. Also, I get the added benefit of maybe 20% or so faster
    recycle times. The only really BAD thing about L-I batteries that I
    found to my horror is that they give very little warning when they
    are getting low on charge. I saw a low battery light come on my
    430EX but ignored it. Within just 2 or 3 more flashes, the damn
    thing went completely dead! I could cycle the power on and off and
    play with the many options but it would no longer charge on recyle.
    So, I now keep a mental note on about how many flashes I've used on
    a set of batteries and either carry another 4 in my pocket or a set
    of cheap alkalines for backup.

    Probably not. The SB-800 has an external power source terminal,
    but the SB-600 doesn't. If you had an SB-800 you might need to rig
    up your own power source anyway, as the ones Nikon sells don't
    appear to run off A.C. power. One of them, the SD-9, uses 6 C
    cells, so that might be sufficient (if you had an SB-800). The
    other two use AA cells. The SD-8A uses 6 and the SK-6/SK-6A uses 4
    AA cells, so neither of these would be adequate if the SB-800 was
    used at full power.

    As noted in the manual, the SB-600 can get up to 400 flashes using
    lithium AA cells, up to 200 using alkalines, and up to 220 using
    2000 mAh NiMH cells (or nearly 300 flashes using 2700 mAh cells),
    where the speedlight is used at full power. If you're able to use
    the flash at reduced power, you could easily get 1,200 flashes per
    charge. With lithium or 2,700mAh NiMH cells, that would require
    using the flash at 1/4 power. With 220mAh NiMH or alkaline cells,
    you could get 1,200 flashes with the SB-600 set to 1/8 power.

    If you're not normally near the camera but can return periodically
    to swap fresh for depleted batteries, you might be able to shoot all
    1,200 shots with the SB-600 at full power.

    Here's a last idea if a "smart" flash isn't needed. You might be
    able to do the job if you can find a cheap, non-Nikon, manual flash
    that's able to be powered externally. The cost might even be less
    or not much more than what Nikon would have charged for one of its
    external flash power sources, if one existed for the SB-600. :)

    True, when lithium batteries die, they do so more quickly than
    alkalines, but they do give another warning. As they're used (at
    least with an SB-600 or SB-800) the flash recycle time slows from
    7.5 to 30 seconds. I'd guess it would be hard to use the change in
    recharge time to determine remaining battery life unless all of your
    flashes were at full power, though. There are several other reasons
    (besides cost) to avoid using lithium AA cells, unless you need the
    greatest number of shots per set. For one, they take much more time
    to recharge high power flashes (such as Nikon's SB-series) than NiMH
    cells, which Nikon says can take less than 3 seconds, vs. 7.5
    seconds when using lithium cells. Also, lithium cells generate much
    more heat when used. Because of this they have internal circuitry
    that temporarily shuts them down when they overheat. This can
    easily happen when a high power external flash is used to take many
    consecutive pictures. This tendency to shut down is probably why
    some P&S cameras state that lithium cells shouldn't be used to power
    the cameras. If they'd shut down to cool while a picture was being
    saved to the flash card, it's likely that some or all of the
    pictures on the card might be lost. Then, not only would the camera
    be inoperable, but if fresh batteries were put in the camera (or the
    camera was tried later, after the lithium AA cells had time to
    cool), due to having a corrupt memory card, the camera might not
    even be able to take any additional pictures and the photographer
    might likely miss the fact that the fault was a result of battery,
    not camera failure.
