I have a couple of wind up Eurohike led lanterns that also charge off the car battery - found a 2 for 1 offer at one of the camping chains. They have done well over the summer but it's been a bit wet for exhaustive testing. They also collapse for storage and being battery power are safe in the tent - try to find a model that has normal AA rechargables for when they die some day.

there I go again
not too hard really
