CFLs, LEDs And Incandescents, Oh My!

While changing a light bulb is a simple chore, picking the right bulb is more complicated. That's because light bulbs are constantly evolving. The 135-year-old incandescent bulb is more efficient than ever, but new light bulb technologies that use significantly less energy have usurped its authority as the reigning king of bulbs. Since lighting accounts for about 12 percent of the average home's energy usage, it makes sense to choose the most energy-efficient light bulbs.
