someone here on apug is selling a KILLER location battery pack lumedyne light kit.
it is priced VERY well, and is a staple for anyone who doesn't want to deal with cords
if/when using a portable light source.
lumedyne has been around for a long long time, and is a favorite of wedding photographers and others
who don't want plugs.
i have one ( the same kit being sold pretty much ) and it has worked flawlessly since purchased in 1988.

i don't have any connection with the seller other than having a similar kit ( used for newspaper work for years )
and wanting to split up his kit to buy a booster but he wants to sell it all together ...
good for the buyer, bad for me
