Eco Factor: Cheaper, more efficient alternative of CFLs developed at Cambridge University.
Researchers at Cambridge University have developed a new way to produce highly efficient LEDs, which can reduce the cost of LED bulbs from £20 to just £2. These mercury-free LEDs are 12 times more efficient than conventional tungsten bulbs and three times more efficient than CFLs. Apart from being cheap and efficient, researchers claim that these bulbs have a lifespan of a whopping 60 years or 100,000 hours of operation, which is ten times more than the conventional eco-bulbs available on the shelves today.
It is being reckoned that these bulbs could slash household lighting bills by three-quarters and if used the world over they could stop 40 million tons of carbon dioxide from being released into the atmosphere. Manufacturers claim that work on the prototypes has already begun and the first bulbs could be on the market in two years.
The Dark Side:
Designing eco-bulbs is just one part of the deal, but educating people about the positive aspects of their use is the most important part.
