Optimizing Operating Life for LED-based Light Bulbs

The replacement of incandescent lighting mandated by the largest countries around the world is powering a paradigm shift to solid-state lighting. LED lighting offers significant advantages over alternative lighting technologies, especially as the lumens per watt increases and the cost per lumen decreases. One of the main benefits with these replacement technologies is the actual life time of the bulb and its cost/watt-hour comparison to traditional incandescent bulbs. While a traditional incandescent bulb has a life expectancy of 1000 hours, LED bulbs offer the promise of up to 50,000 hours of operating time.
