What is the difference between LED lighting and a conventional bulb?

Quelle est la différence entre un éclairage par LED et une ampoule classique ?

The electric light bulb, invented by Thomas Edison in the late 19th century, has been an essential element in homes and businesses for over a century. However, with the advent of LED lighting technology, there is now a viable alternative that is growing in popularity. So the question is: what is the difference between the two lights?

How it works

Let's start with the basic difference... Conventional bulb lighting works by heating a filament until it glows and emits light. In contrast, LED lighting works by passing an electric current through a semiconductor material, which then emits light.

One of the main differences between LED lighting and traditional bulb lighting is their energy efficiency. LED lamps consume much less energy than traditional bulbs. This is because LEDs convert most of the energy they consume into light, whereas traditional bulbs waste much of the energy they consume in the form of heat.


Another important difference between the two types of bulbs is their lifespan. LED lamps generally have a much longer lifespan than traditional bulbs. Indeed, LED bulbs do not have a filament that can burn, which is the most common cause of failure of traditional bulbs. In fact, LED bulbs can last up to 25 times longer than traditional bulbs.

The diversity

The color temperature of the light produced is another factor that differentiates LED lighting from traditional bulb lighting. LED bulbs offer a much wider range of color temperatures than traditional bulbs. This means you can choose a warm, yellow light or a cooler, bluish light, depending on your preference. Traditional light bulbs, on the other hand, generally produce a warm, yellow light.

The environment

Finally, we must not forget that LED lighting is also more environmentally friendly than lighting with traditional bulbs. LED bulbs do not contain harmful chemicals, such as mercury, found in many traditional bulbs. This means LED bulbs are safer to dispose of and less harmful to the environment.

While traditional light bulbs have been a reliable source of lighting for over a century, LED lighting is quickly becoming the option of choice for those looking for a more efficient and cost-effective way to illuminate their homes and businesses. So, your choice is made?
