Bulbs being replaced by light-emitting microchips
There's a significant change taking place in how we light up things according to this New York Times story (registration required):
Incandescent bulbs, neon tubes and fluorescent lamps are starting to give way to light-emitting microchips that work longer, use less power and allow designers to use light in ways they never have before.
The chips — 18 million of them — are already on display in the $37 million Nasdaq sign in Times Square. They are in the vibrant facade of the Goodman Theater in Chicago and adorned last year's White House Christmas tree. More notable, the chips are penetrating blue-collar tasks like illuminating traffic lights, brake lights and exit signs.
