Which is better, a solar lamp made by Bright New Ideas on site in Nicaragua or a home made kerosene lamp?

This video was filmed 29 March 2008 in the community of La Hermita, Jinotega in northern Nicaragua where there is no access to electricity and likely will not ever be any. These children have class in this building, which is also a house. As you can see, when I asked which is better, the answer was, “…the solar lamp is better because it gives more light and the kerosene lamp uses oil.”
