Any idea of the battery run time on these? AAA cells don't have much power (AA cells have about 3 times the power). I find stuff that runs on AAA cells just last a few hours or just barely get through an evening... not good for emergency use during power failures that last an entire night or for days. So I usually avoid items that run on AAA cells.
For outdoor use far from fresh batteries, the power grid, & emergencies, AA cell operated devices are a far better choice. "D" cell power is even better.
