Dunno if this should just be a generic thread for "must haves" or what.
Anyhoo...
http://www.amazon.com/Energizer-Weather-Ready-Folding-Lantern/dp/B001D937SY/They can be found locally, I think I saw them in Walmart (not sure), but I know I picked mine up at Menards.
Takes 4 D-cell batteries. Coin screwed battery flap.
135hr of run time at 'low' setting (off, nightlight, low, high) ... which puts out enough light to do any task (I'd guess around 80 lumens). The nightlight is an orange and is a fairly bright nightlight.
135 hours at 'low' can be verified easily by myself. Rather, that is, I've been using one for over a month and it's been awesome.
Caveats:
* Not water proof
* Power switch can be easy to bump, if you store it in a volatile area, flip one of the batteries around to avoid accidental discharge
* If you're "that way", this *does* require batteries and isn't a person-powered device.
