Great bright hope to end battle of the light bulbs

A story in the Mail Online is one of the most heartening stories I have read for ages. I would never have dreamed 2 years ago that light bulbs would be a subject near and dear to my heart.

I totally detest those energy efficient fluorescent ones. I struggle enough coping with light because of my frozen left pupil without having to deal with the nauseating and headache inducing flicker and color.
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.

The bulbs fully illuminate instantly, unlike the current generation of eco-bulbs.

It is reckoned the bulbs, which were unveiled yesterday, could slash household lighting bills by three-quarters.

If installed in every home and office, they could cut the proportion of electricity used for lights from 20 per cent to 5 per cent a year. As well as lasting 100,000 hours, ten times as long as today's eco-bulbs, the LED bulbs do not contain mercury, so disposal is less damaging to the environment, and they do not flicker - a problem that has been blamed for migraines and epileptic fits.

I can't wait for them to reach the market in the US.
