Big Bucks for Bulb Replacement

Incandescent Light bulb, one of your house old Must-Have item for many years since this greatest invention was created 130 years ago by Thomas Edison.
However, this common article has something that would surprise you, When I was young my father told me not to take out the bulb hen it is glowing, was the filament is so fragile that could be broken mush easily when it is hot. Same thing applies to my beloved Telefunken ECC803 or Mullard 12AX7 Vacuum Tubes. They are made with heater with similar configuration as the Incandescent light bulbs.
Here are a few facts about the light bulb that has been lightening your house for many years.
1.) He is not the best to produce Lights
In fact as little as 1 watt out of every 50 that you put in contributes to actual light. The rest are lost to background heat. (A tungsten filament must be heated to between 3,000 and 5,000 degrees F to get it to glow).
2.)If we did away with them, they could power 2 cities the size of New York for free —By recent estimates, households and businesses in the United States lose about $18 billion every year to inefficiencies in lighting. In terms of power, that's enough to light up a city twice the size of New York for a whole year.
3.) Short life Span
Another thing that incandescent light bulbs are known for, besides the radiant heat, is their lifespan. Glowing for an average of about 1,000 hours before burning out. This short life span is also a built-in benefit for the light bulb companies. Bulbs that burn out once a year are replaced at a rate of 650 million per year in the U.S. alone. That's close to $2 billion in household spending directly attributed to incandescent inefficiency.
4.) Replacing the light bulb hasn't been easy. In reality, the incandescent light bulb has been on the way out for decades, but the transition hasn't been easy... Offices stopped using incandescent as their primary source of light back in the 1950s; today, the bulb's apparent replacement (the fluorescent tube) has emerged as a major culprit in the battle for the environment.
With mercury being a key ingredient in the millions of fluorescent tubes we use at work every day, disposal is turning into an industrial nightmare. A T5 CFL Cold Fluorescent Tube pollutions 10 tons of water in its life cycle. Today, the costs of cleanup — not to mention other shortcomings in the technology — have caused many businesses to start turning their backs on the once revered florescent.
Hope did not die with the fluorescent alternative...The Bright Idea did not die with the fluorescent alternative...
Because right now, there is an unprecedented push to make another light source the preferred commercial lighting solution of the 21st century. That is one of the top ten Inventions in 20th Century. It's so effective, in fact, that grocery stores are already using it in their refrigerated display cases because it produces very little background heat at all.
And it's so efficient that it needs just 18 watts of power to produce the same amount of light as a 100 watt Edison bulb.


This is the LED, Light Emitting Diode!
