For the Multitude

One company that is working in this area is SunNight Solar Enterprises of Houston, TX. Through grants from the Rockefeller Foundation and assistance from the NASA Space Alliance Technology Outreach Program, SunNight Solar has developed a rugged, dependable, solar rechargeable line of flashlights (SN-2 and MiniBogo) certified for use in third-world environment. The SN-2 model is a 2nd generation design utilizing 3 NiMH AA batteries that recharge via the built in solar panel and only need to be replaced every 2-3 years. By simply setting the flashlight in the sun for ~8hrs, the batteries are fully charged providing 4-5 hours of reading quality light. Both lights utilize high quality white LED lights with life expectancies of 10+ years. The light also features a carbiner style hook on the end to allow it be easily suspended from a nail or rope from the ceiling. This 2nd generation design, unlike its predecessor (the SL-1) includes 6 power settings to maximize battery life depending on the specific needs of the user.
