    People need light for daily activities, but in some places in the world, access to reliable power is a problem, and natural disasters can make the matter worse.

Andrea Sreshta and Anna Stork understand how important light is to people in need. After the 2010 earthquake in Haiti, Andrea and Anna, then graduate students in architecture and design at Columbia University, wanted to do something to help.

So as a school assignment, they designed a lighting product that was lightweight, portable  and  wireless,  something  that  might  help  improve  the  safety  and  living conditions of Haitians. The result was the LuminAID light. An inflatable( 可充气的 )plastic, waterproof rectangle light that can be recharged with solar power. What was only a school project for them soon became something much more when friends and contacts began sending the lights to those in need.

In their final year of architecture school, Andrea and Anna filed a patent for the lamp, and shortly after graduating, they went to India to conduct field tests on their prototype( 维形). Anna says visiting villages without stable access to electricity was really meaningful to them. “It helped us understand the houses and the conditions that these people were living in. And what was so interesting is one of the villages that we’ve visited. The house was made out of really thick cement( 水泥), so even in the daytime, it was completely dark inside the house. So we saw real need for portable lighting, “Anna says.

In 2011, Andrea and Anna launched their business LuminAID. They say that after hearing from people who use the lights, they now realize how important their product is.
