Q: How many LED engineers does it take to change a light bulb?

A: Why on Earth would you ever need to change a light bulb?

While LED (light-emitting diode) costs are still high, this type of lighting is extremely long-lasting. And as prices come down, its efficiency could lead to huge energy savings.

The first consumer LED products lit up in the 1970s, with red light numbers on pocket calculators and push-button displays on big, geeky Pulsar watches. Then came those centered, high-mounted brake lights in the rear windows of cars. Now LEDs are found in everything from traffic lights to operating rooms to greenhouses.
