This statement is a heresy! Everyone knows the game about the “weakest link”... This applies perfectly to the luminous sources with LED technology. LED spotlights and bulbs are assemblies of components, but which component is the weakest link in this assembly?
The diode itself has a life span of 100,000 hours, but the transformer (or ballast) does not work for more than 30,000 hours. The transformer that regulates the LED current is, therefore, the assembly’s “weakest link”, which will limit the life span of a LED luminous light for the general public to 30,000 hours. So, for the moment, systematically avoid products announced as having life spans of more than 30,000 hours.
