Incandescent bulbs may be in real decline as suppliers can now offer more efficient options. Top choices are fluorescent, CFL, and LED bulbs, but LEDs are clearly the most efficient. They use less electricity, (less than $2 a year), they use fewer resources to make, they produce 90% less heat, and they last 20 years.

However, LEDs can be a tough sell because they are expensive to purchase; it can be a real investment to light a house. And, what about waste considerations if old lightbulbs seem fine? However they clearly save energy and money over the life of the bulb.

According to LEDWaves, replacing one incandescent bulb with an LED pays the buyer back. After that, the they return for another 18.5 years!
