SunNight Solar developed these lights with help from NASA, among others, and tested them in some pretty tough conditions, so they should survive your son's room. The flashlight absorbs sunlight during the day through its handle and converts it into electric light at night. It gives off more than 6,000 hours of illumination on one set of AA batteries (though they use more-expensive batteries than usual). If you buy one on the BoGo program, the company will send one to a charity you choose from a list; you'll learn that there's no shortage of places where nighttime illumination would make a huge difference in people's lives. Buy one, give one — hence, BoGo. — Belinda Luscombe
