How Long Do LED Bulbs Last? A Detailed Look at the Lifespan of LEDs

How long do LED bulbs last? This is a question that many people have, and it’s a valid one. LEDs are becoming more and more popular, so it’s important to know how long they will last. In this article, we will explore the lifespan of LED bulbs and answer the question of how long they typically last. We’ll also look at some factors that can affect their lifespan. So if you’re curious about LED bulbs, keep reading!

How Long Do LED Bulbs Last?

You may be wondering how long do LED bulbs last? How many years will they shine brightly before their light dims and dies out? Well, it depends on a few factors. The lifespan of an LED bulb can range from about 25,000 hours to over 100,000 hours! This is because there are different types of LEDs with varying lifespans based on the materials used in their construction and manufacturing processes. Some manufacturers have even claimed that their products have an estimated 50-year lifespan when used 24/seven days per week at 12hrs each day (or 30k hrs).

Generally, LED bulbs last longer when they’re turned off than when they’re on. This is because LEDs don’t experience the same kind of heat build-up that incandescent and fluorescent bulbs do. When an LED bulb is turned off, its temperature drops quickly, which helps to preserve the lifespan of the light. However, if an LED bulb is turned on and then immediately turned off again, this can actually shorten its lifespan a bit. So if you want your LED bulbs to last as long as possible, try not to turn them on and off frequently.

Do led light burn out?

LED bulbs do not burn out. Rather, they lose their ability to emit light over time and this is known as lumen depreciation. How quickly this happens varies depending on factors like temperature or how much current flows through the bulb. But, in general, LED bulbs will slowly lose brightness over their lifetime.

This is why it’s important to buy a bulb that has a higher lumen rating than the light you’re replacing. For instance, if you’re replacing a 60-watt incandescent with an LED bulb, make sure to get one with a minimum of 600 lumens. That way, even as the bulb decreases in brightness over time, it will still be brighter than your old one!

How do you calculate lifespan of led light?

An LED module may have a life expectancy of 50,000 hours. If the module is on for 12 hours per day, it could last more than 11 years. If left on 24/seven days per week at 12hrs each day (or 30k hrs), an LED module will last about five and one half years.

LEDs are a more efficient type of lighting, and they use less energy than incandescent or fluorescent bulbs. This is why many people are making the switch to LED lights. Not only do they last longer, but they also consume less electricity, which can save you money in the long run.

5 things you can do to extend the lifespan of your light bulb

While LED bulbs last a long time, there are some things you can do to help them last even longer. Here are five tips for extending the lifespan of your light bulb:

– Use a surge protector: If you’re using multiple LEDs in one area, make sure to use a surge protector. This will prevent any power surges from damaging the bulbs.

– Keep them cool: LEDs generate less heat than other types of bulbs, but it’s still important to keep them cool if you want them to last longer. Try not to place LEDs in direct sunlight or near heat sources.

– Don’t overuse them: Just like anything else, don’t use your LED bulbs too often or they’ll wear out sooner. Try not to leave them on for more than eight hours at a time.

– Clean up spills right away: If any liquid gets on an LED bulb, it can cause corrosion and shorten the product’s lifespan. Wipe up spills as soon as they happen with a dry cloth or paper towel so that they don’t have time to do damage!

– Use dimmers sparingly: Dimmers are great if you want to change the brightness of your lights, but using them too often will wear out an LED bulb faster than if it were just left at one setting all day long.

How Long Do Led Bulbs Last When You Turn Them Off And On Again?

When switching between different lighting types, it can be difficult to know how long they will actually last. LED bulbs are known for their durability and longevity but they do have one weakness: overheating. If you try turning off your LED light bulb too soon after turning them on, there is a good chance that the bulb might explode or even shatter into little pieces of glass! So if you want to intentionally damage your light bulb, try turning it off and on again as soon as possible. However, with normal usage, an LED bulb should last over 30,000 hours!


LED bulbs last for a very long time and they do not burn out like incandescent or fluorescent light bulbs. To make sure that LED bulb lasts as long as possible, keep the bulb cool by keeping it away from heat sources and don’t overuse it. I am really enjoying these low-wattage fluorescents, especially since I am able to string many of them together without fear of blowing a fuse. The dimmable capability also allows me to use canned lighting wisely and in some cases completely hides the lights when unnecessary. 

Although these are much more expensive than incandescent, their cost is well worth it when considering the amount of energy saved every month which could be considerable depending on how often you replace your bulbs. And if that’s not enough, think about how much money you won’t have to spend on replacement lightbulbs too!  

Hopefully this article will help people who had the same question as me to determine LED lifespan for their particular usage scenario.
