Do you have proof it is an urban legend?

The Light Bulb

The original incandescent light bulb was invented by British chemist Sir Humphry Davy (1778–1829) in 1805 although it would be another seventy-five years before Thomas Edison found a way for them to be used commercially. Then, in 1924, the leading light-bulb manufacturers formed the International Phoebus Cartel with the aim of standardizing light-bulb fittings. However, many believed that the cartel was actually formed to suppress the invention of the life-long light bulb. It was a new design that would never need to be replaced. In fact, the cartel went one step further and all agreed to actually limit the life expectancy of a light bulb, which would increase the demand for replacements. Some men of science claim that the patent for the lifetime light bulb, along with its technical information, is ‘buried somewhere in a drawer’ at the head office of one of the major light-bulb manufacturers.

It should be pointed out that there is no actual evidence for this although it is known that the average lifespan of a light bulb, in the Western world, is around 2,000 hours, whilst those in the former communist countries, who were not part of the cartel, has around double that life expectancy. Modern Chinese bulbs are estimated to last up to three times as long. Now, despite there being no evidence to support such claims, it is known that German watchmaker Dieter Binninger (1938–1991) invented a light bulb that was estimated to last 150,000 hours of continual use, or eighteen years. However, soon after finding a manufacturer who agreed to actually produce them, Binninger mysteriously died in an aircraft accident in 1991 and his invention quietly disappeared from focus. Murder in the light-bulb business, or conspiracy theory?
On another note, LED lights suppress melatonin and are therefore harmful to health.
