There are roughly 500 million light bulbs in California, Incandescent bulbs account for 80 percent those in use.  Incandescent bulbs give off a lovely warm light, but they're not the most energy efficient.

Now there's a new bulb is on the scene: the CREE bulb. 

Its makers say it provides natural-looking light while using just a fraction of the energy of traditional bulbs. Electical engineer Margery Conner joins the show to tell us what's different about this bulb.
