4 Factors that influence the lifespan of LEDs

The introduction of LED lighting solutions has been one of the biggest transformations in the lighting domain. According to lighting experts, LEDs are sustainable, eco-friendly, efficient, and safe lighting solutions that deliver multiple benefits to the users.

In addition, LED lights are known to last longer and typically enjoy a lifespan of almost 50,000 hours. However, just like all other lighting devices, even LED lights are vulnerable to damage and breakdowns due to various factors.

As suggested by the top commercial lighting manufacturers, here are some of the factors that can influence the lifespan of LED luminaires:

1. Power supply

According to lighting experts, operating luminaires above their recommended power requirement can significantly reduce their life. LED bulbs require a reliable power supply (commonly known as a driver) that assists in maximizing the power output and life expectancy. It ensures optimal supply of electricity that eventually helps in controlling and regulating the voltage. Thus, people are always advised to buy high-grade LED lights with integrated drivers.

2. Ambient temperature

The temperature of the location (where an LED bulb is installed) in known to largely influence the life of an LED luminaire. As per LED lighting manufacturers, enclosed lighting fixtures can experience a surge in the ambient temperature that can affect the chip and the driver. This can significantly reduce the lifespan of the luminaire. Thus, people are suggested to install LED lights in locations that flourish enough space for heat to dissipate and allow proper cooling.

3. Capacitors and drivers

In the earlier days, LED luminaire drivers used plastic capacitors for storing energy. When used on a regular basis, these capacitors would only last for a year. As per lighting experts, the plastic capacitors were largely affected by external factors like heat and ambient temperature, and hence, experienced a shorter lifespan. However, LED lighting manufacturers are now using ceramic capacitors in their LED drivers as they possess a higher tolerance against heat to ensure a longer life.

4. Heat emission

Chips and heat sinks in the LED light bulb are sensitive to high temperatures. For instance, if the temperature of an LED luminaire crosses 85°C, the life of the latter is expected to reduce. Thus, the temperature of the bulbs should be below the above-mentioned temperature. This is beneficial not only for the heat sink but also for the life of the luminaire.

Apart from the above-mentioned factors, people are also strongly suggested to buy only top quality (with warranty) LED lights as cheaper and inexpensive alternatives are vulnerable to pre-mature malfunctioning.
