Consumer Reports has show that 3 out of 4 Americans prefer CFLs to LEDs, mainly based on LED’s high cost. In spite of current expensive price, LED bulbs have their advantages as following.
Keeps strong when turned on and off frequently
Consumer Reports put CFLs and LEDs side by side and turned them on and off every two minutes. Some CFLs burned out, but all the LEDs were still going strong after 200,000 cycles.
Dimmed as low as an incandescent bulb
Unlike CFLs, some LEDs can be dimmed as low as an incandescent bulb. Additionally, they come to full brightness instantly.
Consumer Reports also tests light bulbs' brightness and color temperature.
"We found that some LEDs have the same warm glow as incandescents," said Dan DiClerico with 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.
Prices are expected to keep on dropping
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," DiClerico said.
So which LED are best? Among 60-watt equivalents, Consumer Reports top-rated two: 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 have come down dramatically, as bulbs that are now $25 were nearly $50 a year ago. And prices are expected to keep on dropping.
Free from mercury
LEDs don't contain any mercury. That means cleanup is easier if a bulb happens to break. And when they finally burn out, years and years and years from now, you just put them in the trash.
And don't worry about the yellow color you see at the store. The second that LED light goes on, the light is white.
