Researchers Conquer "LED Droop" 113
sciencehabit writes "Tiny and efficient, light-emitting diodes (LEDs) are supposed to be the bright future of illumination. But they perform best at only low power, enough for a flashlight or the screen of your cellphone. If you increase the current enough for them to light a room like an old-fashioned incandescent bulb, their vaunted efficiency nosedives. It's called LED droop, and it's a real drag on the industry. Now, researchers have found a way to build more efficient LEDs that get more kick from the same amount of current—especially in the hard-to-manufacture green and blue parts of the spectrum."

Contact a doctor if you LED lasts more than 100000 hours.

" They are not bulbs, they're bloody diodes!"
Nobody uses bloody diodes for lighting. Not only is it un-hygenic, the loss of efficiency due to transmitting the light through blood is unacceptable, not to mention the red tinge to the light itself.
Everybody uses clean diodes.

Apparently this droop issue is only a problem for non-blue wavelengths. At least if my subwoofer, PC and external HDD are anything to go by...
My eyes hurt.

I think you mean lead painted with something else toxic to make it shiny?

That's impossible. Lights have to be in a bulb shape, because that's how they've always been, and people don't like change.
I suspect in a lot of households, one half doesn't care what their "light bulbs" look like so long as they save them money, and one half doesn't care how much they cost to run so long as they look right in their decorative light fixtures. Typically the "it has to look right" half wins the buying decision.
