I have high hopes that LED lighting will open new paths for both decorative and edible urban greenscaping, As we city dwellers know, adequate lighting is often the limiting factor. This news from the U.K. is most encouraging.
A lighting revolution is on the way that could end at the flick of a switch the battle between supporters of conventional bulbs and the eco-friendly variety.
Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost £2 and last up to 60 years.
Despite being smaller than a penny, they are 12 times more efficient than conventional tungsten bulbs and three times more efficient than the unpopular fluorescent low-energy versions.

Even better, the bulbs fully illuminate instantly, unlike the current generation of eco-bulbs.
It is reckoned the bulbs, which were funded by the Engineering and Physical Sciences Research Council, could slash household lighting bills by three-quarters.
