20 Year light bulb?

[La Poste]

Light bulbs that are said to last for more than two decades while consuming very little energy may go on sale later this year.

US firm General Electric, Dutch company Philips and UK-based Sylvania all showcased their products at the Light Fair industry conference in Las Vegas.




BBC News - LED light bulb to last more than 20 years

Looks funky.

Surely that would be like a cure for cancer? Kept secret so companies can continue to sell drugs.

You would think it would have a warranty for twelve months and be designed to last twelve months and a day.

I'm such a cynic.....

The '20 years' is most likely more of an estimate. I can't imagine these were invented 20 years ago and they've been testing them ever since, they probably just expect them to last that long (on average).

Some of the Phillips GU10 lamps(!) come with a 2 year warranty. The benefits of LEDs are clear enough to us but I think the general public will need more convincing as it will probably be marketed as another euro conspiracy to ban our fantastic 100 watt bulbs that keep leaving burn marks on the ceiling

"All three bulbs are meant to last more than 20 years, if used about three hours per day."

That's England out then....

This is nowt new .... Me Ma & Da moved into their house in June 1951 & there was a light in the hall that lasted until 1976.

Joseph Swan excelled himself there !!

Lamps were always capable of lasting decades. The pre-burn was introduced to reduce lifespan and increase sales.

Will it fit in with all the tulip & Daff bulbs?

Agree with Guitarist, they have had the technology for years to produce extra life long lamps. Why sell only one bulb every 20 years when we can sell one bulb a year?

Yes I called them bulbs .

Nothing wrong with that mate. A generic term which everyone understands. Whenever I tell a non-sparky that I need to change/replace a "lamp", they always assume that I mean the fitting....

Has anybody been in a situation where someone genuinely thought you were going to go outside and start digging up the flowers to make the lights work?
