If we are talking about cheap incandescent lamps, then they are still reliable within their limits. This is because we are talking about a basic design that has been perfected over many years. In the case of LEDs, things are completely different. However, buying cheap LED lights can be very expensive!
Buying LED lights can be very inexpensive!
Each LED includes a circuit and an LED in place of the primary metal spacer. This panel converts the voltage and deals with any problems and irregularities that occur in your home’s electrical system. That is, it is something more complicated compared to ordinary lights.
Now if you buy many bulbs for an almost unbelievable price, don’t be surprised if they fail.
High temperature
Electronic devices hate heat, and the tiny circuit boards inside LEDs are no exception. In addition to the problem we mentioned with regard to cheap bulbs, there is another problem. Heat is the number one killer of LEDs.
The big problem in most cases is the built-in lamps. Especially the ones we put on the ceiling. That’s why there are some special lights that can be used in this way.
Here we usually talk about cheap LED lights. Is that in the most economical there are always some materials that are excluded. You have to save somewhere for the final cost to come down. For this reason, cheap LEDs are very light because they lack adequate heat dissipation (more expensive LEDs will have little weight because the base of the lamp has a lot of aluminum mass to keep the heat from the LED and the circuit board).
voltage problems
These problems can arise for several reasons. It may have a damaged wire or a bad connection. This occurs when the problem only appears in one lamp or fixture. Sometimes it can be as simple as bending a contact breaker into a lamp socket. But if there is no reason for the LEDs to fail prematurely, there could be a much larger electrical problem. LED lights are particularly sensitive to voltage issues.
If you notice that the LED lights go out with the switch on or turn on and off intermittently, this may indicate voltage problems.
