How Long Do LED Lights Last? Our EASY Guide

Many homeowners and businesses have been replacing their old halogen bulbs with LED bulbs to make their light fixtures more environmentally friendly, and brighter.

However, before installing new LED lights it’s a good idea to research how long they should last you. For those wondering “How long do LED lights last?” read on for our comprehensive guide.

How Long Do LED Lights Last On Average

The typical LED bulb should last between 30,000 and 50,000 hours (1). Some bulbs will last longer than 50,000, but only under certain factors, usually pertaining to the temperature, type of fixture used, and their power supply. In addition, advances in technology inspire their further development:

The ability of LED technology to produce high-quality white light with unprecedented energy efficiency is the primary motivation for the intense level of research and development currently supported by the U.S. Department of Energy.

With research and development in full force, some LED lights have been working for more than ten years, so answering the question “How long do LED lights last?” is still being determined.

How Does Temperature Affect LED Longevity

Temperature plays a factor in the longevity of LED lights.

Cold temperatures do not affect an LED bulb’s life expectancy, but heat does.

Many light fixtures like LED solar flood lights have heat sinks to move heat away from the LED bulb. Fixtures that do not have heat sinks can cause LED bulbs to overheat and stop working because the heat travels back into the bulb. 

If you use a LED bulb outside, the cold temperature will not shorten its life expectancy. 

How Do You Lengthen the Lifespan of an LED Light

LED light bulbs should last up to 10 years, especially if you take care of them properly. To keep your investments lighting the way, be sure you are using an appropriate light fixture and the necessary power supply. 

If you find that your LED bulbs are dying quickly, the problem could be in the light fixture’s voltage. 

Lack of ventilation or a warm environment can cause LEDs to fail quickly. The bulbs need ventilation so they can cool.

Unlike incandescent bulbs that work with electrical currents and filaments, LED bulbs are complex. You get what you pay for when buying LED lights, so those made by quality manufacturers usually last longer.

What Types of LED Lights Last the Longest

LED lights come in several forms and can be used in offices as overhead lights, lamps, floodlights, decorative lights, and more. Different types of LED bulbs have varying lifespans.

Some manufacturers make LED products with LED bulbs that aren’t meant for light output for more than three hours per day. If you use these bulbs for more than three consecutive hours, those bulbs will fail quickly. Read the details before buying a new LED bulb that you expect to last for 20+ years.

This fantastic video by Headlight Revolution details exactly what you can expect for some of the most popular LEDs on the market:

Ultimately, A well-built LED bulb in a LED lamp can be on all day and still last for over 25,000 hours (2). Compare that to an incandescent bulb that lasts about 1,000 hours (3). Plus, LED bulbs don’t cost 25 times more than incandescent ones.

LED bulbs used in linear fixtures (like those in offices), last significantly longer than incandescent ones and can use nearly 70% less energy than the old-fashioned filament bulbs (4). This type of LED bulb often lasts longer than others because it is built for hours of daily use.

These types of savings can add up quickly:

The new report estimates annual U.S. energy savings of 1.3 quadrillion Btu (quads) in 2018 due to LED adoption, equivalent to cost savings of $14.7 billion for consumers and about 5% of total electricity use from buildings in 2018.

You can also increase your energy savings with long-lasting outdoor bulbs, low-high bay bulbs, and A-type bulbs because they last about the same amount of time as incandescent ones. However, they can save you between 22% and 53% more energy (4).

In the end, LED bulbs usually cost more than incandescent bulbs, but good LED bulbs last significantly longer and they lower energy costs over that time.

FAQs

LED Christmas lights can last for up to 40 holiday seasons according to Energy.gov (5).

Anyone who has used incandescent Christmas lights knows that a few always burn out and need replacing. On the other hand, LEDs can last much longer than the standard 500 hours per holiday season, or as long as 20,000 hours (5).

Despite working for much longer than incandescent lights, LED Christmas lights use significantly less energy. The US Department of Energy claims that LED Christmas lights use 70% less energy than conventional incandescent lights (6).

Integrated LED lights can last you over 20 years depending on how many hours a day you use them (2).

Integrated LED lights are built right into the fixture so it’s important that they’re built-to-last. They’re used in a wide variety of lighting technology like LED lamps, solar lamp posts, and solar flag pole lights. Integrated light fixtures can have a life expectancy of more than 25,000 hours in many cases (2).

On average, LED tea lights can last for up to 100 hours with a quality power supply before the battery needs replacing, according to manufacturers. If you keep replacing the battery, you can get thousands of hours out of the little LED light bulbs.
