Though claimed featuring a perfect energy saving property long ago, LED hasn’t been widely used yet due to its high cost of up to 28 dollars each. But that’s no longer true after the Cambridge University researchers have developed the cheap LED bulbs that are priced at merely $2.85 each. Even better, the new LEDs are much brighter than usual one and can last quite a long time of up to 60 years.
