These include batteries, sound recording, motion pictures, telegraphs and telephones, mining, concrete buildings and furniture, and a safety lamp for miners. Edison won the prestigious Rathenau Medal for the miners’ safety lamp, but his foray into concrete furniture was less successful—the idea never took hold.

His inventions included the phonograph, the carbon-button transmitter for the telephone speaker and microphone, the incandescent lamp, the first commercial electric light and power system, an experimental electric railroad, and key elements of motion-picture equipment.

Though Thomas Edison is usually credited with the invention of the light bulb, the famous American inventor wasn’t the only one who contributed to the development of this revolutionary technology.

Different filaments, filament designs, and connections were tested over time and by the mid-1920s most lightbulbs lasted, on average, about 1,200 hours apiece.

The world’s longest-lasting light bulb is the Centennial Light located at 4550 East Avenue, Livermore, California. It is maintained by the Livermore-Pleasanton Fire Department. The fire department claims that the bulb is at least 119 years old (installed 1901) and has only been turned off a handful of times.

Thanks to the evolution of LED technology, however, there are compelling LED Edison bulbs that are more durable and efficient than incandescent filaments. They still produce less light than regular LED bulbs, but the filaments produce a warm color temperature for a pleasant and energy-efficient glow in your home.

A distinguishing feature of the Thomas Edison light bulb is that you can look straight at it without hurting your eyes. This means they can be used bare, without shades or anything else blurring their light. Edison lights are often used on lamps and accent lighting in general.

Edison bulbs are very high in demand because they are cost-effective, stylish, warm and healthy. These features are rare to find in one delicate glass bulb. That’s why still after so many years, these bulbs are highly popular, especially among interior decorators and art lovers.

Why does a light bulb turn black? Over the life of an incandescent light bulb, the filament begins to deteriorate and the particles will settle on the inside of the glass. In return the bulb will take on a grayish appearance and a slight decrease in light output may occur.

There are many possible reasons why a light bulb burns out quickly: The power supply voltage may be too high. Bulbs may be loose or connected improperly. Excessive vibrations may be causing the filament to break.

The most common reasons for LED blowing out are high voltage, bad contacts, use of incompatible dimmer switch, or recessed lighting. Other causes include overheating due to not using the right fixtures, or simply a bad batch of lightbulbs!

Habitually loose connections, either at the socket or with the wire connections, can burn out the bulb quickly, as well as cause flickering. These loose connections increase the electrical resistance and the heat passing through the filament of the bulb, which can shorten its life.

LED lights do not emit light from a vacuum as most other bulb types do. Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly lower temperature than other bulbs.
