lightbulbs that last decades?

while traditional lightbulbs emit just 5% of their power as light, and fluorescent tubes about 15%, the Ceravision lamp has an efficiency greater than 50%.

Because the lamp has no filament, the scientists who developed it think it will last for thousands of hours of use—in other words, decades.

I think most lamps last for thousands of hours of use, already. Decades, however, is an entirely different story...

That's awesome. Comparably sized to LEDs but brighter, more efficient, and decade lasting? WHen do these things go on sale to the general public?

Here's a video demonstrating a lightning technology that sounds similar:
