UK Company, Ceravision, have created a new bulb design that doesn’t use electrodes, so cannot burn out. It uses a magnetometer to bombard a small piece of aluminum oxide with microwaves to create an electrical field. Gas is then passed into a hole in the aluminium, in order to ionise it and create a glowing plasma.
Ceravision is a privately owned lighting company based in Bletchley Park, UK Ceravision is the inventor of a range of electrodeless lamps and integrated luminaires...
Electrodeless lamps have been recognized, since Nikola Tesla filed his original patent in 1894, as having a number of advantages:
* No electrodes to break - so potentially very long life
* No chemical degradation of the electrodes - so much lower lumen loss and discoloration during life
* No reactive metal inside the bulb - so the ability to use much more efficient fill materials
A UK firm has developed a bulb that is more than 3 times as efficient as CFL bulbs and will burn brightly for decades. They claim that it will burn for so long that the building or appliance that contains it will wear out before the bulb does.
Planned obsolescence or built-in obsolescence is the process of a product becoming obsolete and/or non-functional after a certain period or amount of use in a way that is planned or designed by the manufacturer. Planned obsolescence has potential benefits for a producer because the product fails and the consumer is under pressure to purchase again, whether from the same manufacturer (a replacement part or a newer model), or from a competitor which might also rely on planned obsolescence.  The purpose of planned obsolescence is to hide the real cost per use from the consumer, and charge a higher price than they would otherwise be willing to pay (or would be unwilling to spend all at once).
If marketers expect a product to become obsolete they can design it to last for a specific lifetime. For example, if a product will be technically or stylistically obsolete in five years, many marketers will design the product so it will only last for that time. This is done through a technical process called value engineering.
Software companies are sometimes thought to deliberately drop support for older technologies as a calculated attempt to force users to purchase new products to replace those made obsolete
Planned systemic obsolescence is the deliberate attempt to make a product obsolete by altering the system in which it is used in such a way as to make its continued use difficult. For example, new software is frequently introduced that is not compatible with older software.
this artificially limits the life of the battery. The IC will not permit the device to charge the battery any more than the IC dictates. Production of these batteries is usually stopped at around the same time the product is discontinued, therefore rendering the product worthless once the batteries start to wear out.
Some companies have developed a version of obsolescence in which the product informs the user when it is time to buy a replacement.
Edison and the Eternal Light Thomas Edison designed a bulb that was supposed to last forever, called the Eternal Light, and turned it on on October 22, 1929. The bulb is located in the Memorial Tower at the Edison Memorial Museum in Menlo Park, New Jersey. The tower fell down in 1937, but the bulb's power was supposedly uninterrupted, according to General Electric, and continued to burn while a second tower was constructed. According to museum curator Jack Stanley, the bulb is fake, consisting of a hollow bulb illuminated by a series of automobile headlights mounted in the display's base.
