High cost has thus far limited widespread adoption of LED lighting, which is far more efficient than either incandescent or compactfluorescentlighting.
Remember those bi-partisan Congressional votes phasing out incandescent light bulbs in favor of fragile mercury-laden, landfill-destined compactfluorescentlighting to clearly dispel any such illusions.
The intersection of new energy efficiency regulations and the maturation of the technology mean LEDs, which are more efficient than even compactfluorescent bulbs, are the future of lighting.
It was also a big week for lighting news as we learned that compactfluorescent light bulbs emit potentially harmful UV radiation -- another good reason to make the switch to LEDs.
