With the new energy bill, (passed December 2007), making incandescent lighting prohibited for sale in stores by the year 2012, the old "light bulb" joke takes on a new twist, especially if the alternative is LED lighting.

"LED lighting is 70-80% more efficient than traditional lighting and can create some very dramatic  lighting effects," states Roger Hale, energy consultant and owner of Commercial LED Lighting in Florida, "but the real asset of LED technology is the length of time these lights last."

"Conservatively, we estimate that LED lights will last for at least 12 to 15 years, giving them a clear advantage over halogen and compact fluorescent lighting, (CFL)".
