LED light bulbs are more durable, energy-efficient and long lasting compared to others. LEDs have a general life expectancy of 50 000 hrs. If you use your lights for 10 hours a day, this should be 13.7 years.If you are wondering how long an LED light bulb does, then read the following blog to understand the lifespan of LED.

Parameters that affect the lifespan of LED

Heat Sink

Designing a heat sink is a fine science.   The heat sink is used for the effective cooling of lighting system in LED lights. It should have a low thermal resistance. Some heat sinks don’t have the right amount of surface area while some don’t have proper gap between fins to enable air flow. Due to these design faults, the heat rises and thus decrease the LED lifetime.

Capacitors

Capacitors are used in the circuit of each LED driver. They are made up of plastic, aluminum or ceramic. The plastic and aluminum capacitors last for about 1 year, if used daily then ceramic capacitors have very long life.

Temperature

LED lights are usually designed to work in a dry environment. If they are used in a hot country, or enclosed area, the heat around them can easily surpass the heat and they were designed to withstand, shortening their life time.

The long lifespan of LED light bulbs is one of their biggest benefits. Unlike halogen or incandescent bulbs, LEDs do not require frequent maintenance and once installed, will not need replacing for years.  The lifespan of a LED lights is calculated via lumen depreciation (the decrease in lumen output). There are different lumen maintenance ratings like L50, L70, L80 and L90. To know more about lighting, talk to our experts at LETDesign Lighting consultants India today.
