Return of incandescent light bulbs as MIT makes them more efficient than LEDs

Ever since the EU restricted sales of traditional incandescent light bulbs, homeowners have complained about the shortcomings of their energy-efficient replacements.

The clinical white beam of LEDs and frustrating time-delay of 'green' lighting has left many hankering after the instant, bright warm glow of traditional filament bulbs.

But now scientists in the US believe they have come up with a solution which could see a reprieve for incandescent bulbs.

Researchers at MIT have shown that by surrounding the filament with a special crystal structure in the glass they can bounce back the energy which is usually lost in heat, while still allowing the light through.

They refer to the technique as 'recycling light' because the energy which would usually escape into the air is redirected back to the filament where it can create new light.

"It recycles the energy that would otherwise be wasted," said Professor Marin Soljacic.

An incandescent used in a home that needs heat is 100% efficient already.

And the article is wrong about LED light. They come in warm colors just like incandescents.

Not all incandescent bulbs are outlawed. Just the ones I have hoarded.

They will cost as much as the new ones. Of all the problems the world had, Bush solved the problem of making sure I couldn’t have a normal lightbulb.

Is there an LED light that gives natural spectrum light?

Fred Upton (Rino-MI) was the chief congressional ahole, FYI.

It would be nice to be able to see again and to not swear every time I have to face going down the “light” bulb aisle and figure, while trying to figure out what I need.

True story - I'm re-plumbing the cabin when I first got it and the contractor ended up throwing up a well-house over my well on very short notice. We got it done before dark and it was starting to get cold. He told his son to stick a light bulb inside for overnight heat until we got the heater wired in. Morning comes, water's frozen. What the heck? And there, reposing in splendor, was a CFL bulb giving off plenty of light..."but Dad, they're more efficient", the kid said later. "Are you related to me?" he sez...

Same here.....went to the dollar store & purchased enough of the old bulbs to last over 20 years.

Didn’t he also “fix” all our toilets so that we have to flush them twice? The Booshes have all been bungholes, and this last one is braindead to boot!

It was the ONLY thing to do!

I get migraine headaches...those damned "new" bulbs bring on an aura; I go blind for about 20 minutes and then the migraine hits...NO THANK YOU!

That depends on what you mean by natural spectrum light.

Reminds me of the scene from Smokey and the Bandit.
