Yeah, when HF used to have the freebie giveaways, I'd make a point of
collecting the little 3AAA LED lights to scatter around the house
for "close in" work. A shame they are AAA instead of AA!

The lights use so little current, the AAA batteries hold up considerably longer
than the old D cell and "bulb" combination.

Perhaps. OTOH, I never *buy* batteries to replace the (crappy)
batteries that come with the lights.

And, while I've not taken one apart to verify, I suspect the
lights rely on the internal series resistance of the batteries
to limit the current to the LED's (no "ballast").
