My favorite Light!

[TrainChaser]

I like Luci Lights... flip them over and place them in the sun during the day, push the button and read by them at night. If the inflatable plastic casing gets punctured, you can trim it all off and just use the bottom panel (velcro might be good). "Set it in direct sunlight for 7 hours and Luci Original lasts up to 12 hours on a single charge."
