An addendum to my previous post. Another very fine solar powered light would be any of the Luci (brand name) inflatable lights. There are probably other makes which follow the same basic scheme. A small solar panel, an array of LEDs, and an inflatable bag provide a very fine diffuse light, suitable for dining or use in a tent. They are also very cheap and quite compact when not inflated. In uninflated condition, they perform decently as a flashlight.
