Can we replace all fluorescent bulbs with LED, soon?

Presently, there is already LED version of the long soft glowing tubes found in most offices and homes. But these LED tubes are very expensive and are not widely used.

What Phillips is doing is to develop an LED light that will be "far more efficient than the best fluorescents on the market. Greener and cheaper."

Goodbye fluorescent bulb? Philips says yes

Top executive at Dutch company Phillips said the prototype LED is headed to mass production and will hit the market in 2015. He claimed that in 10 years, LEDs will replace at least half of the world's fluorescent bulbs, which have been the main source of workplace lighting since shortly after World War II.

"This is a major step forward for the lighting world. It will bring an enormous savings in energy."- Rene van Schooten, CEO of Philips' light sources division.

Experts outside the Dutch company say they have long expected LEDs to eclipse fluorescents. If Philips' predictions are correct, however, the arrival of the LED in office spaces will come faster than expected.

Huge potential of LED tubes

Lights suck up more than 15% of all energy produced globally, and fluorescent lights currently make up more than half of the total lighting market.

In the United States alone, fluorescents consume about 200 terawatts annually, according to Philips' estimates. Cutting that in half would save $12 billion in electricity costs and lessen carbon dioxide emissions by 60 million metric tons per year, the company said.

The technical milestone the company claims to have achieved is the ability to produce 200 lumens of light per watt. That's about twice the output per watt of the best fluorescent tubes currently on the market.

A lumen is the standard measure of the amount of light a lamp casts in a given area.

"LEDs will take over, definitely within 10 years, certainly within 5 years, maybe within three." - Rene van Schooten.

Yes we have to do this; LED bulbs are solid and energy saving lighting bulbs which are extremely energy efficient. Florescent lighting bulb have their own different advantages, it will provide lighting source which look more beautiful. Other side, LEDs is limited to single-bulb that is used in different applications such as instruments, electronics equipments, and more other lights.
