Researchers Conquer "LED Droop"

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."

That's daft. With LEDs if you want more light, you simply use more LEDs. They are not bulbs, they're bloody diodes! Overdriving LEDs results in earth deaths, this has been known for 40+ years, keeping them within tolerances will ensure they'll last forever, or as near it in human terms.
