Lighting and the Smart Grid Achieving these benefits requires: Achieving these benefits requires:  an intelligent lighting system, and  a better light source. SPGTC Presentation | 7 Basic Benefits of LED Lights  Approaching most efficient A hi t ffi i t light source  Lower heat output  Very long life (50,000 hrs) y g ( , )  Environmentally rugged (no breakage mercury) breakage, mercury)  Improved light quality  Start instantly, inherently dimmable in efficient ways SPGTC Presentation | 8
