In the debate over whether compact flourescent lights (CFLs) or light emitting diodes (LEDs) are going to join Betamax and HD DVDs in the up-and-coming technology graveyard, opponents of LEDs for normal in-home use will say that they're too sterile. We are seeing LEDs that give off a warmer vibe, but they aren't as energy efficient or long-lasting as basic LEDs. But the Associated Press reports that a company recently "showed off an LED lamp that's both very power-efficient and produces a light similar to that of a standard tungsten or halogen bulb."

The Quantum Light lamp, made by Nexxus Lighting Inc., features a light source of LEDs that shine through a thin layer of "quantum dots."

Sound too space-agey for you? Quantum dots are tiny particles (about 10,000 fit across the width of a human hair) that allow different colors of light to pass through depending on their exact size. So the shade of light that you get through the dots can be controlled precisely to give harsh LED lights a warmer glow without giving up any of the benefits that made LEDs a smart choice in the first place.

Having just been announced, the lamp isn't available yet. But you can bookmark Nexxus' online store to keep an eye on it.
