LED light bulb scientists win Nobel prize

Three scientists transition to the domestic LED lighting has won the 2014 Nobel Prize in physics component.

Shuji Nakamura, Isamu Akasaki and macros Amano efficient co-inventor of the blue light-emitting diode, which in combination with phosphorus or red and green LED can produce white light for the home and office.

Since the early nineties he was a breakthrough, LED technology has come a long way - you can now buy LED bulbs in just five pounds for your home.

However, you can also pay up to 40 pounds. To ensure that you do not spend more money than you want bulbs, LED bulbs are what we put through rigorous testing to indicate which is the best - you can not tell just by looking at the price tag.

Our test results show that the first led string light of their rights to produce packaging requirements, which differ most is what the packaging and printing of 20% longer lamp failure. You can view our complete test results, LED bulbs to determine which light bulb is our most cost-effective review.

Advantages of LED bulbs
For now, LED is the most expensive conventional types of bulbs you see in the store. But they do have advantages over other types of energy-saving light bulbs:

LED is the most energy-efficient lamps. They use 90 percent less energy than conventional bulbs, more efficient than halogen lamps and compact fluorescent lamps. Six 50W halogen lamps, reflecting the typical two hours a day spent £ 36 a year. LED will cost less than £ 4 a year.
LED can last 25~30 years, depending on you to buy and how to use it.
Now, you can buy a light bulb can produce enough light to replace the old incandescent 100W.
LED lights are now able to produce the same color light as conventional bulbs - warm white light at 2700 Kelvin.
LED indicator lights up almost immediately when you cross the switch, so do not put the dim light, they go.
Thing to note LED bulbs
This relatively new solar led lighting technology is not without problems. Here are some things to consider before you decide to make the switch:

In order to dim LED lights, you may need to upgrade to a dimmer, detection of low electrical load. The package should be said, LED is dimmable, but if you are unsure, contact the manufacturer.
LED has a low CRI (color rendering index) - is how different colors of light to display only measures; for example, how do you see your red tomatoes chopping block. For now, the best LED scores obtained in the mid-1980s. Although it is still higher than the acceptable level, the traditional incandescent and halogen high scores in the 90s.
What testing of all types of energy-saving light bulbs instead of the LED. So, whether you want a cheap and cheerful bulb garage or attention in your kitchen high specification, you should be able to use our test results, in order to obtain the correct bulb for your needs and budget.
