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.
