History of LED since Times before Thomas Edison

We’ve come a long way from the times before Thomas Edison, and the invention of the light-bulb. Before the light-bulb, people had to use candles and gas-lamps, but today, we have LED lights and even gravity bulbs which are powered by a bag of rocks that slowly drops to turn an electric motor and make light. These gravity lights are helping third-world countries and towns provide light to their citizens. We can talk about all the different lighting sources and fixtures, but in this article, we will discuss one in specific, LED Tubular lighting.

LED Lighting

LED is an acronym that stands for “light emitting diode”. This is a device that emits light when a current of electricity passes through it. They are used in flashlights, on clocks, and other applications like small robots and where you see small lights flickering.

Because LEDs are more efficient and last a lot longer than other types of lights, they have started to be used instead of regular light bulbs. Some areas where they are used instead of light bulbs are in the red lights installed on car bumpers, lights on the street, office ceiling lights, and some decorative lighting as well.

These lights have a light span of 100,000 hours, which if left on every day for all twenty-four hours, would not need to be replaced for 4,166 days or the equivalent of eleven years. The other reason why they are beginning to substitute traditional light bulbs is that not only are they energy-efficient, they are brighter while using less energy. Flat screen TVs have also begun to incorporate LEDs into their screens’ backlights, replacing LCD displays.

LED Tubes

LED tubes are a separate category of LED lighting. Certain light fixtures need special types of LED tubes to function. You can’t just put any type, as you will either be frustrated that it doesn’t fit, or it may not work when you turn on the light switch. LED replacement tubes have now begun to implement what is called “linear fluorescent tubes”. These tubes include T12, T10, and t8 led tubes which are labeled this way from the diameter of each tube, with T8 being close to the smallest. The smallest of these tubes is the T5 which is only 5/8 of an inch in diameter.


In conclusion, there are many more details about LED lighting that we can discuss, but in this article, we were focused on only on LED, and LED tubes in particular. We’ve discussed our evolution as a species using gas lamps before the invention of the light bulb, to our current age where we have begun to replace the light bulb with LEDs. LED is an acronym for the light emitting diode, and it can last for a very long time. It is a very energy-efficient option for homeowners and anywhere where light bulbs are needed.
