LED bulbs are much more efficient at producing light than are traditional incandescent bulbs. They initially cost much more, but last far longer and use much less electricity An LED bulb that produces as much light as a 100 W incandescent bulb uses only 12.5 W of power. The LED bulb lasts 15,000 hours, on the average, and costs £8.00, whereas the cost of an incandescent bulb was only £0.75, but it lasted just 750 hourS. Assume that electricity costs £0 122 per kilowatt-hour and that the bulbs are on for 4.0 h per day.
