Under normal circumstances and barring manufacturing defects or transformer failures, LEDs are designed to continue functioning within the specified lifespan provided by the manufacturer. However, as time goes on, they may gradually decrease in intensity.

Several factors can influence the actual lifespan of a light source. These factors include ambient temperature, the luminaire's cooling system, the presence of proper ventilation in ceiling spaces, how often the light is turned on and off, and the overall quality of the LED.

Typically, a light source integrated into a luminaire tends to have a longer lifespan compared to a replaceable LED bulb. When selecting lighting for your home, understanding the expected lifespan of the light source and how it may be influenced by various factors can help you make informed decisions about lighting maintenance and replacements.
