LED lighting at the crossroads: country road or expressway? (MAGAZINE)
The LED lighting industry faces five major roadblocks, but if these can be overcome then the market will be able to accelerate rapidly, say Florian Wunderlich, Dominik Wee and Oliver Vogler.
LED is truly a revolutionary lighting technology. It offers a number of important features, including many that cannot be matched by existing incandescent, compact fluorescent (CFL), or halogen lights. Among LEDs' advantages are greater color variability, instant-on capability, dimming capacity, and freedom in design. The efficiency of LED lamps makes them significantly superior to CFL today in terms of total cost of ownership (TCO), as LED bulbs can generate more than 100 lumens per watt of electricity against 60-75 lm/W for CFLs while lasting three to five times longer. LEDs' fully-loaded costs become lower than those of typical fluorescent lights in roughly 6 years.
