Understanding LED Lifespan and Life Expectancy

This article explores the lifespan and life expectancy of LED (Light Emitting Diode) lighting. Generally, LEDs boast an impressive lifespan, ranging from approximately 50,000 to 100,000 hours.

At a usage rate of 10 hours per day, this translates to a lifespan of roughly 13.7 to 27.4 years. However, this number can fluctuate based on several factors, primarily the quality of the external components connected to the LED bulb.

Other significant elements that influence LED lifespan include:

• Temperature: Overheating can drastically reduce the life of an LED.
• Drive Level: Pushing an LED beyond its recommended current can lead to premature failure.
• Power Supply: A stable and clean power supply is essential for consistent performance and longevity.
• Environment: Factors like humidity and exposure to corrosive substances can impact the lifespan.

Smart LED Lifespan Examples

Consider the examples of smart LED bulbs.

• GE Link Smart LED Bulb: This Zigbee-supported bulb offers a lifespan of approximately 23 years.
• Philips Hue LED Bulb: The Philips Hue bulb has a life expectancy of about 10 years.

Calculating LED Lifespan

The following formula can be used to calculate the estimated lifespan of an LED in years:

$\text{LED Lifespan (Years)} = \frac{\text{Total Life in Hours}}{\text{Daily Consumption in Hours} \times 365}$

Example:

• Total life in Hours (Input #1): 50,000
• Daily Consumption in Hours (Input #2): 10
• LED Lifespan in Years (Output): 13.69
