LED Bulbs

LED bulbs, also known as retrofit bulbs, are replacing the traditional halogen bulbs. While they last much longer than halogens, their lifespan is still limited by the electronics in the lighting and the need for proper cooling. LED bulbs run on the existing voltage of halogen bulbs, and overheating can cause them to stop working. Additionally, frequently switching the light on and off won’t extend their lifespan. On average, LED bulbs can last between 20,000 – 25,000 hours.

Integrated LED

Integrated LED refers to LED lighting that is built directly into the fixture. One downside of this setup is that if the LED stops working, you’ll need to replace the entire fixture. However, the benefit is that integrated LEDs have an exceptionally long lifespan. The power supply is usually separate from the LED, which allows for easier replacement if it fails. The average lifespan of an LED integrated in a fixture is around 40,000 to 50,000 hours, although this can vary depending on the quality of the LED chips.

LED Modules

LED modules offer a combination of the previous two options. These modules can be directly connected to the power supply, eliminating the need for additional fittings. All the components are separate, with the necessary electronics located in the external power supply. If the power supply fails, it can be easily replaced without replacing the LED module. However, LED modules may be more challenging to use in fixtures with unique shapes. The average lifespan of LED modules is also around 40,000 to 50,000 hours.

In Practice

To put these numbers into perspective, let’s consider some practical examples:

• In a shop where lights are on for 9 hours a day, LED lights can last approximately 8 years and 10 months.

• In offices open for an average of 250 days a year, with lights on for 10 hours a day, LED lights will last for about 10 years.

• In a living room, where lights are typically on for around 3 hours per day, LED lights can last an impressive 23 years and 9 months.

• In the bathroom, where lights are used less frequently, with just 1 hour of usage per day, LED lights can potentially last as long as 71 years and 5 months.

It’s important to note that these calculations do not account for potential wear-and-tear on the electronics. If the electronics fail, the LED will no longer work. Nonetheless, the advancements in LED technology are promising, and we can expect even longer-lasting LEDs in the future.
