Light bulb vs. LED: Where is the difference?


led and incandescent lights advantages and disadvantages
If you're still using light bulbs, it's high time to switch to LED. LEDs are not only more energy efficient, but also more durable. The days are over when LEDs only gave off with cool white light. Meanwhile, models are available that look like classic light bulbs.

Key facts at a glance:

·        Light bulbs are inexpensive but have a huge energy consumption
·        LEDs are expensive to buy but more environmentally friendly and energy efficient
·        Therefore it is worth changing from light bulbs to LEDs

How light bulbs and LEDs workLight bulb

A conventional light bulb generates light through the filament in a low-oxygen glass ball. Once the bulb is connected to a voltage source, the filament is heated so much that it generates light.

LED

LED stands for "light-emitting diode". A diode is an electrical device with two electrodes, which allows the current to pass unimpeded in one direction and to isolate it in the other. As a result of the constant movements of the electrons in the semiconductor material, this produces light.

Advantages and disadvantagesLight bulb

Light bulbs are inexpensive because you can buy them from just one euro. Furthermore, they have a perfect color rendition, as they always have a color rendering index of 100 and thus guarantee perfect, vivid colors. Unfortunately, light bulbs have a very high energy consumption. They have the worst energy efficiency of all Types of lighting. This is because about 90% of the energy needed to heat the filament of the lamp is lost. This leads to a short life of the lamp. Light bulbs burn on average only 1,000 hours. If you use bulbs on average only four hours a day, they will not even last nine months. As a result, you'll need to change the bulbs more frequently, which will cost you money. Since 2009, the production of light bulbs by the EU has been gradually banned. If you are still using bulbs, you should switch to an alternative such as LED bulbs.

LEDs

At the beginning of the LEDs, they emitted a typically cool white, slightly bluish light. This is not the case anymore. LEDs are available in virtually all shapes and color temperatures, which are known from other lamps - such as light bulbs or halogen lamps. For LEDs, there are initially higher initial costs than for bulbs. However, these costs pay for themselves in no time, because the luminaires can demonstrate low energy consumption. When switching to LED you can save up to 80%. As a result, the average lifespan is about 35,000 to 50,000 hours, which guarantees a fast payback period usually within one year. In addition, LEDs are environmentally friendly: Unlike traditional bulbs, they contain no toxic chemicals.
