Although it is likely that the ever evolving light bulb will continue to improve it’s efficiency over time, none of these improvements would be possible were it not for many great innovators over the past 200 years. Energy Professionals is committed to finding its customers the best possible rates on electricity and natural gas.
Why did early light bulbs have such a short lifespan?
These early bulbs had extremely short lifespans, were too expensive to produce or used too much energy. When Edison and his researchers at Menlo Park came onto the lighting scene, they focused on improving the filament -- first testing carbon, then platinum, before finally returning to a carbon filament.
How did the light bulb evolve?
In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp.
How did Thomas Edison improve the light bulb?
Edison changed all this in October 1879 when he filed his patent titled “Improvements In Electric Lights.” Edison introduced a carbon filament light bulb that was brighter, cheaper to make, and lasted 1,200 hours.
How long did Edison's light bulb last?

The Halogen Bulb is an enhanced, and technologically advanced version of an Incandescent light bulb. It works the same as an incandescent light bulb, but with a twist. There is an inert gas enclosed inside the vacuum, in order to enhance the lifespan of the filament.
What temperature do arc lamped rods have to be vaporized at?
The rods of the arc-lamped have to be vaporized at a very high-temperature (~3600C), in order to start the ionization process. This ionization process takes place between the carbon ions, and the air ions to produce electric light.

People were staying up later in the evenings because of the lighting they now had, cities became more social in the evenings, and homes were safer now ...
How does a light bulb work?
Two wires travel from the metal contacts to a thin metal filament in the middle of the bulb. The glass bulb that surrounds the wires and filament contains an inert gas, usually argon. When an electrical current powers the light bulb, the energy travels through the wires to the filament to create light. The modern-day light bulb, in more scientific terms, radiates light by a reaction between positively and negatively charged atoms.
How do fluorescent bulbs work?
The light works by an electric current traveling from cathodes on the ends of the bulb to the gases, which radiate energy. The tubes have a phosphorus coating, which takes the energy and converts it to light.

Today, there are fluorescent lamps, compact fluorescent lamp (CFL) bulbs, halogen bulbs, and light-emitting diode (LED) bulbs.
How did Edison create the first light bulb?
When Edison designed the first light bulb, it worked with the power of electricity. The electricity traveled through a glass vacuum bulb to a delicate platinum filament to provide the light. The vacuum of the glass bulb would slow down the melting of the filament. This bulb would only last a few hours before burning out.
Who invented the light bulb?
It is widely believed that Thomas Edison was the inventor of the very first light bulb in 1879? The actual history of the light bulb is quite a bit older than that.
What is the fastest developing lighting technology?
One of the fastest developing lighting technologies today is the light-emitting diode (or LED). In 1962 while working for General Electric, Nick Holonyak, Jr. invented the first visible-spectrum LED. These breakthroughs led to LEDs being used in a variety of applications including traffic lights, flashlights and TVs.
Why did Edison merge with others?
Eventually Edison’s company merged with others working in the field to collaborate their efforts. While Edison definitely moved the light bulbs progress forward more than any other individual, he really was building off of the works of many other scientists and inventors.
Why do people use arc lights?
With the invention of the electric generator, which greatly reduced the consumption of power, people used arc lights for searchlights. For the next 40 plus years scientists continued to improve on the filament which is the part of the bulb that produces light when heated by an electrical current.
How did Hewitt create blue green light?
Hewitt created a blue-green light by passing an electric current through mercury vapor and incorporating a ballast. While these lamps were much more efficient than incandescent bulbs there was little interest commercially due to the color of the light.

What are the advantages of incandescent bulbs?
Modern incandescent bulbs are not energy efficient – less than 10% of electrical power supplied to the bulb is converted into visible light. The remaining energy is lost as heat. However these inefficient light bulbs are still widely used today due to many advantages such as: 1 wide, low-cost availability 2 easy incorporation into electrical systems 3 adaptable for small systems 4 low voltage operation, such as in battery powered devices 5 wide shape and size availability
How long does carbon filament last?

How much energy is lost in an incandescent bulb?
The remaining energy is lost as heat. However these inefficient light bulbs are still widely used today due to many advantages such as:
Why is Edison so famous?
However, Edison is often credited with the invention because his version was able to outstrip the earlier versions because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable.
When did Edison start making light bulbs?
This discovery marked the beginning of commerically manufactured light bulbs and in 1880, Thomas Edison’s company, Edison Electric Light Company begain marketing its new product.
What was the name of the lamp that he made with carbon?
When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp. And while it produced light, it didn’t produce it for long and was much too bright for practical use.
How did Edison make the first light bulb?
It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting. Still, the lamp only burned for a few short hours. In order to improve the bulb, Edison needed all the persistence he had learned years before in his basement laboratory. He tested thousands and thousands of other materials to use for the filament. He even thought about using tungsten, which is the metal used for light bulb filaments now, but he couldn't work with it given the tools available at that time.
How did Thomas Edison make incandescent light?
Incandescent lamps make light by using electricity to heat a thin strip of material (called a filament) until it gets hot enough to glow.
What was Edison's lamp made of?
Edison's lamp would consist of a filament housed in a glass vacuum bulb. He had his own glass blowing shed where the fragile bulbs were carefully crafted for his experiments. Edison was trying to come up with a high resistance system that would require far less electrical power than was used for the arc lamps.
How old is the Edison bulb?
It is a product of the continued improvements Edison made to the 1879 bulb. Even though it is over a hundred years old, this bulb looks very much like the light bulbs lighting your house right now. The base, or socket, on this 19th century lamp is similar to the ones still used today.
What metal was used in Edison's light bulb?
He even thought about using tungsten, which is the metal used for light bulb filaments now, but he couldn't work with it given the tools available at that time. One day, Edison was sitting in his laboratory absent-mindedly rolling a piece of compressed carbon between his fingers.
