These days, fewer and fewer traditional incandescent lightbulbs are being used in homes. This is because lightbulb technology has improved since incandescent bulbs were developed. Incandescent bulbs work by running electricity through a wire inside the bulb. The wire glows, creating light. However, incandescent bulbs waste a lot of electricity by producing heat rather than light. In the past several years, less wasteful LED lights and compact fluorescent bulbs have become increasingly popular for home use.
