I am looking for cheap (under $5.00) headlamps that run on 1 x AA battery to be given away to the volunteer workers at my club's dog agility trials. The cheapos I find are all 3xAAA, and by the time I put in 3 lithium primaries I have spent more on batteries than on the light, plus I know the recipients will mostly put alkalines in when the original batteries run down. If i give them a spare lithium primary AA they will have light for a fair while.
Until now I have been giving them all fauxtons, but they all (well, all the regular workers, anyway) have as many fauxtons as they want by now, so it is time for something different. I might consider giving them the choice between a headlamp, cheap multi-tool or a flashing pendant light for their dog's collar.
Any suggestions ?
