Recognizing that the incumbent conventional lighting technologies will compete with new LED lighting products, the lighting market model allows for both cost reductions and performance improvements in efficacy and lifetime for conventional lighting technologies (i.e., incandescent, halogen, fluorescent, and HID) and LEDs. Technology performance improvements are also adjusted to account for existing legislative and regulatory energy conservation standards that take effect in future years. The lighting market model primarily uses adjusted price and performance curves for LED lighting based on data published in the 2013 SSL Pricing and Efficacy Trend Analysis for Utility Program Planning
