I did not take any of these photos (sadly). These lights are rechargeable and solar powered and are often the only light source available other than traditional kerosene lamps or candles - both of which are dangerous and very costly. I designed the electronics and have had a major prt in most other aspects. The lights are usually donated BUT even at full cost they pay for themselves in fuel savings in under 6 months. The smaller lights seen here are fully waterproof, very shock resistant, will float and use among the most efficient LEDs available.
