Inventors in Silicon Valley have unveiled a light the size of a pill which has the luminary power of a streetlamp. Engineers at Luxim Labs filled the bulb with argon gas, which turns to plasma when electricity is focused through it. The resulting light is insanely bright, and twice as efficient as the current efficiency king, the LED.
Implications - No street will ever be left in the dark if these plasma bulbs make it out to a mass audience. Who would have ever guessed that something so tiny could produce so much bright light? With a spectrum similar to the sun, even nighttime will feel like it's as bright as day.
