A 1999 white paper predicted a revolution in lighting technology by extrapolating the 30-year history of red LEDs to estimate the performance and cost for white LED lamps for the following two decades. In this Expert Opinion (pp. 17–29), Haitz and Tsao discuss the hits and misses of the 1999 predictions and analyze the necessary and sufficient conditions for this revolution to succeed. The graph on the cover updates the flux and cost performance for red and white LEDs and confirms that these 1999 predictions still hold. The global wave of investments in R&D and manufacturing infrastructure triggered by the 1999 graph will continue, thus leaving little doubt that this disruptive technology will dominate the lighting industry, not this year or the next, but over the next two decades.
