1 P08427 LED Lighting Technologies for a Sustainable Lighting Solution in Developing Nations Detail Design Review 6 February 2009

2 Design Review Objectives To receive feedback on the aspects of our current design Come away with direction for the final stages of the project – Suggested changes to the design – Additional prototype verification that should be conducted Be ready to provide the best possible product to our end users. Please Feel Free to Ask Questions at any Time
