Now you have me thinking about small hydro storage again.  ;D
Here is a guy's system that uses a 55 gal drum on his roof.  He fills it using a solar panel and has a custom Pelton wheel driven generator to light an LED.  The amount of energy stored is about the same as a AA battery.  Your light could go for a long time on one drum of water.  Maybe you could fill a bag of water, pull it up into a tree and get some light for an entire evening.
