More and more manufacturers are equipping their lamps with built-in LEDs. In this article you can read about the point and what can be done if such a lamp breaks. On how best to avoid this problem.
Lifespan of LEDs
Technically speaking, the lifespan of LED lights is between 20.000 and 50.000 hours. With average use of a lamp, this can mean between 15 and 50 years.

Due to the long service life of many lamps, replacing the light source is out of the question - at least not for the manufacturer. Even assuming a service life of only 10.000 hours goes out, which corresponds to between 8 and 10 years, when designing the lamp you usually do not need to reckon with the replacement of the light source.
In practice it has been shown that the service life of lamps with permanently installed LEDs can be significantly shorter. Often the lamps only last a few thousand hours.
The reason for this cannot always be determined. In some cases, one suspects insufficient heat dissipation, which often causes quality LEDs to overheat and then no longer function, despite all built-in heat protection devices.
Basically, the manufacturer has to prove in tests that the lamps have a minimum shelf life of 6.000 hours. However, this only applies for 50% of all lamps. Up to half of the lamps can also have a shorter lifespan in a test.
Reason for permanent installation
The manufacturer has several reasons for permanently installing the light source:
- the design and construction of the lamp is simpler and less complex
- A lamp change is usually not taken into account as the service life of the LED is often longer than the service life of the lamp (at least in theory)
- Since fewer moving parts are built in, the construction of the lamp is simpler and more cost-effective
Compared to a classic ceiling lamp with light bulbs, which had to be replaced regularly, LED lamps have completely different characteristics. Here the light source often lasts longer than the lamp is in use.
Change the lamp
Theoretically, you can have LEDs in the lamp replaced if they are defective - in practice that rarely stands for this. The costs for this are usually not economical. So it is better not to buy lamps with permanently installed LEDs.Tips & Tricks Make sure when you buy whether and how the light sources in the lamp you have bought can be replaced. If in doubt, ask again before buying. It would be a shame to throw away an entire lamp just because replacing an LED light would cost too much money and would no longer be economical.
