LED Solar Lantern...what to do with this?

well it was free..so no complaint's there,im certain it doesnt work...the LED is in the top of the housing,it's just a Single 5 mm Diode...it shines into an internal difuser with a parabolic mirrored piece of plastic,the black housing at the top also contains a few small solar cells and the battery and circuitry i imagine,the entire thing is made of plastic and the plastic lense is yellowed quite abit,entire thing is plastic so nothing that makes much heat can go inside it..i don't know what i will do with it..im thinking LED's :D
