Are LED lightbulbs worth the extra money?

In a test, lightbulbs are turned on and off every two minutes. Some CFLs burnt out, but all the LEDs are still going strong after 200,000 cycles. And unlike CFLs, some LEDs can be dimmed as low as an incandescent bulb. Another plus - they come to full brightness instantly. Consumer Reports also tests lightbulbs' brightness and color temperature in a sphere, a computer analyzes the results.

"We found that some LEDs have the same warm glow as incandescent," said Dan DiCerico of Consumer Reports.

But not all LED bulbs are stellar, a Miracle LED claims to be equivalent to a 60-watt incandescent, But it's not as bright as a 40-watt bulb. And while it's long lasting, it gives off a strange bluish-white light.

With all LEDs, the big disadvantage is the price; many cost $20 or more per bulb.

"LEDs are more expensive, but they're designed to last so long - 23 years or more - that you'll likely save about $130 over their lifetime," said DiCerico.

So which LEDs are best? Among 60-watt equivalents, Consumer Reports top-rated two are the EcoSmart from Home Depot that produces a white light and a 12.5-watt Philips that has a warmer, yellower light; both cost around $25.

Consumer Reports says prices of LEDs are coming down and are expected to continue to drop. And here's another plus, unlike CFLs, LEDs don't contain any mercury.
