LEDs efficient alternative to phased out incandescent

California decided to replace the least efficient incandescent bulbs one year earlier than the rest of the country. That means 100-watt light bulbs are out because they need to be 72 watts or less. Light-emitting diodes, commonly known as LEDs, are a good alternative because they last a long time, are cooler to the touch and give off great color. Consumer Reports put a variety of LED bulbs through tests in its labs. These bulbs are expensive, anywhere from $17 for a table lamp bulb to more than $60 for a floodlight. "Even with an LED's high cost, you can still save $100 or more over its life compared to a standard incandescent," said Bob Markovich of Consumer Reports.
