GE shows off LED lightbulb -

General Electric said it will market an LED lightbulb towards the end of the year that will only consume nine watts and will last 25 times longer than an incandescent unit.

The unit is designed to replace a common or garden 40 watt bulb and its LED light will pump out 450 lumens in a directed manner.

But the bulb, at least in its first iteration, won't be cheap - it will probably cost around $50.

GE said it designed the Energy Smart LED bulb to direct light downward on the surface and not at the top of a lampshade.

John Strainic, general manager at GE Lighting, said: "This is a bulb that can virtually light your kid's bedroom desk lamp from birth through high school graduation."

GE rates its life at 25,000 hours - that's 17 years at four hours a day. It will be far cooler than incandescent bulbs and cooler than CFL lights.

GE Lighting markets a number of other LED lighting bulbs.
