Incandescent Light Bulb
The average incandescent light bulb uses 60 watts of power, costing you 6 cents for every hour it’s on. By replacing your incandescent light bulbs with more energy-efficient bulbs, you can use 25 to 80 percent less energy.
Compact fluorescent lamps (CFLs), light-emitting diode bulbs (LEDs) and halogen incandescent bulbs use less energy and last longer, although they are more expensive to buy. Of these three types, LEDs are the most efficient, reducing the cost to light a room by 75-80 percent and lasting 25,000 hours compared with the 1,000-hour life of a traditional incandescent bulb.
