From EDN magazine - an article that starts to look at the full environmental impact of conventional and energy efficient lighting technologies.
We have some early estimates on the cradle-to-grave environmental footprint that can be anticipated for Vu1's ESL technology. We believe that this is one more critical attribute that should not be compromised while providing energy efficient lighting. Stay tuned to see how ESL will compare to CFL and LED.
