Team Lumen was tasked with designing an affordable lamp for rural Cambodia to replace kerosene lamps. They observed lamp usage in the area and identified a need for a portable, ambient light source powered by solar energy with no ongoing costs. Their final design, called the Moonlight, features 6 wide-angle LEDs powered by a 0.5 Wp solar panel providing 3 hours of full light and 4 hours of dimmed light on a charge. Feedback from users was positive about the design, ease of use, brightness, and affordability.
