Everyone agrees that the popularity of LEDs is on the rise, and
a variety of businesses are touting the features and benefits
that this new lighting technology brings to a wide array of
applications. So far, lighting designers, architects, and
systems contractors have learned that LEDs are an energy-
efficient, low-heat, and extremely durable lighting solution.
They are changing color options, creative effects, and lighting
designs in venues around the world.  However, many overlook the
fact that LEDs are also changing the way we measure performance.
When making a lighting purchase decision, the average consumer
believes that the higher the wattage, the more light is
produced, but LEDs are changing this standard. How can a 2W LED
bulb emit as much light as a 15W ordinary bulb but use much less
power? Because of LEDs, we can no longer measure useable
brightness in the traditional terms of wattage. Where do we go
from here?  The lighting industry will need to clarify wattage
and performance as they apply to LED
