Understanding LED Light Bulb Lifespan

When it comes to LED lights, since there are many designs, sizes and types, it’s not a round number like you’d think.

However, there are some answers that are more on point than others. Firstly, the lifespan of LEDs directly depends on their current and how often the light is turned on.

If you are planning to leave your LEDs on 24/7 without any other loads on the circuit, your lights should last for up to 50,000 hours, which is equal to five years.

You can even push that to 100,000 hours if the current is half of the max. Although, you shouldn’t be running your LEDs at full brightness all the time.

Temperature can also have an effect on your LEDs. If you have an airflow problem or your lights are located in an area where they could be affected by extreme heat or cold, you can expect the lifespan to be shorter than the expected 50,000 hours.

Also, LEDs actually age. While there is a lifetime rating that you can typically rely on, the emissions from your LEDs won’t be as bright over time.

So How Long Do LED Light Bulbs Last?

Yes, the amount of time your bulb will last is important, especially if you choose an LED light over a regular incandescent light. You don’t want to be forced to choose a new light bulb every few months.

Fortunately, you don’t have to. The life of LED light bulbs is considerably longer than that of other types. They can last for tens of thousands of hours before they need to be replaced.[1]

A lot of factors affect life expectancy, such as the type of bulb, the manufacturing standards, and the overall quality of the bulb.

Some of the lesser-known brands may advertise that their light bulbs will last for 25,000 hours, but how do you know if you really have a quality product? High-quality LED light bulbs have a certified warranty for the lifespan that is guaranteed.

So before you buy one, find out if the manufacturer offers a full warranty. Unfortunately, not every LED light bulb is a quality product. Refer to our FAQ on LED light bulbs for more information.

So Are LED Lights Worth The Money?

LED grow lights are drastically changing the way indoor grows are done.

They’re not only saving growers significant money, they’re also ensuring that the growth of their plants is easy and worry-free.

However, in spite of all these benefits, many growers still run away when they hear the words “LED grow lights” because they’re afraid that investing in the best LED grow lights will only come up short.

The key to understanding LED grow lights is learning about 1 or 2 light systems and their life cycles. A well-made LED light will have a lifespan of 50,000 to 100,000 hours.

If it burns for 24 hours each day that means it will last from anywhere between 4 to 7 or even 8 to 10 years!

At least 85% of growers who have switched to LED grow lights say that the initial investment was definitely worth it due to the increased yields and decreased electricity bills.

It can be challenging to find the best LED grow lights because of the variety of options now available.

This set of questions will allow you to find the one that is best for you. The mantra to remember is that LED grow lights don’t last forever.

Yes, the lifespan of an LED is still better value

For money than fluorescent lights, but how much you will save over time depends a great deal on the quality of the bulbs you use.

A poor quality LED light will not last as long as a quality LED light. The other factor to consider is whether you are buying the lights for use in a warm environment, for example in a home aquarium or in a greenhouse.

If you are, then you are better off opting for a LES (light emitting diode), not a PLES (pink-light emitting diode).
