Nice little 12-LED lantern at Aldi from today for £2.99. Adjustable light level. Takes 3 x AA batteries (included) and has a rubberised finish.
Just bought 2 to hang up in our tent. Obviously these aren't as bright as gas lanterns but you can't hang gas lanterns in a nylon tent, or at least not without burning a hole in the roof!
Lots left in Aldi @ Birchwood.
