What's the 'wow' factor in current, future lighting?

Light Emitting Diodes — they're the real wow! LEDs are high energy efficient semiconductor devises that emit visible light of a certain color; an accelerating transition to LED-based lighting has been changing the dynamics of luminaries design on a global scale. LEDs are already commonplace in products we buy and in the spaces we live, work and play. They provide uniform distribution of a much brighter light, high efficiency, improved flexibility and long-lasting maintenance-free operation — an easy three times the energy efficiency of 60-watt incandescent bulbs and three times the life expectancy. Today's energy audits can provide advanced information as to the energy levels one can save.
