How long do LEDs last?

LEDs are notable for being extremely long-lasting products. Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!

This depends on a number of factors. We will try to give you a clear idea of what exactly you can expect from LED lighting.

LED bulbs

Classic halogen bulbs are being increasingly replaced by LED bulbs, also called retrofit bulbs. These last much longer than halogen bulbs. However, the capacity of LED bulbs is still limited by the electronics in the lighting, which make the LED bulb run on the existing voltage of halogen bulbs. Furthermore, an LED bulb must remain cool. If LED lighting heats up, it will stop working. The limited cooling of retrofit bulbs reduces their life span. Moreover, switching the light on and off frequently will not help improve the number of burning-hours. All things considered, the average life span of an LED bulb is currently around 15,000 hours.

Integrated LED

Integrated LED is LED lighting that is integrated into the fixture. The disadvantage of this is that when the LED stops working, you need to replace the entire fixture. To compensate for this, an integrated LED has an extremely long lifespan. The power supply is usually external and separate from the LED, which is good for the quality of the electronics in the power supply component. If the power supply no longer functions, it can be easily replaced without having to replace the LED. The average life span of an LED integrated in a fixture is 25,000 to 30,000 hours. You should take into account that this may vary a lot. For example, there are still significant differences in quality between different LED chips.

LED modules

A third option is the LED modules. This combines the best of the two abovementioned options. An LED module can be directly connected to the power supply. Hence, no fittings are required. All the components are separate in an LED module. The necessary electronics to make the LED work is located in the external power supply. So if the electronics in the external power supply fail, you can simply replace the power supply component. 

The downside is, however, that LED modules are more difficult to use in fixtures with special shapes. Just as in the case of integrated LEDs, the average life span of LED modules is 25,000 to 30,000 hours. ClickFit spotlights are specially made for LED modules. These spotlights have a clicking system that makes it possible to hold the LED module, without using a fitting.

In practice

Here are some practical examples to give you a better idea of how long 25,000 hours precisely is.

In a shop that is open every day except Sunday and where the lights are on for 9 hours each day, LED lights will last approximately 8 years and 10 months.

Offices are open for an average of 250 days a year. If we assume that the lights stay on for 10 hours each day, here the LED lights will last for 10 years.

In a living room, the lights will be on every day (except for a few days when the family is on vacation), although this will be mainly in the evening. If the lights are on for an average of 3 hours per day, the LED will last 23 years and 9 months.

Naturally, the lights in the bathroom are used much less than in the living room. Here, the LED will last as long as 71 years and 5 months, if the lights are on for 1 hour per day. In this context, it must be mentioned we are not taking into account the wear-and-tear on the electronics of the LED. If the electronics fail, the LED will no longer work. However, an LED that lasts 71 years is (for the time being) a pipe dream.

LED light bulbs are touted for their low energy consumption, and their longevity solidifies them as a worthwhile investment.

LED light bulbs are known for their low energy consumption and capacity to significantly reduce your power bill. Their long performance life further ensures LED lights are a worthwhile investment. Just how long does an LED replacement light bulb last? While it can vary slightly depending on the bulb, on average LED light bulbs last over 50,000 hours. That would be almost six years if left on twenty-four hours, seven days a week. In terms of usage, if you leave your light on all day (16 hours), an LED replacement bulb would last 3,125 days or approximately 8.5 years. If you leave it on only during the evening (4 hours), an LED replacement bulb would last 35 years.

Comparatively speaking, both incandescent and compact fluorescent light bulbs last a mere fraction of that. LEDs last 50 times longer than a traditional incandescent bulb and 10 times longer than a compact fluorescent. While LED replacement light bulbs seem more expensive than their incandescent and compact fluorescent counterparts, when you factor in the significantly lower energy consumption and reduced frequency of purchasing light bulbs, you recoup that initial investment soon.

I was contemplating my own mortality recently, when I realized 2015 passed by in a blur. Ruminating about the loss of yet one more year, I looked at my LED-laden lamp and thought, “Sure, you might last 50,000 hours, while my expiration date is virtually unknown.” But, was this true?

Happy to take the thought process from my own shelf life to that of an LED, I began to wonder if that 50,000, 35,000, or 25,000 hours of use from an LED could possibly be accurate. For one thing, I don’t mark down the date of purchase for my LEDs. Do you?

How long do led lights last on batteries?

How long will one set of batteries last?

This can be fiendishly difficult to predict! Sometimes the only way to be sure is to plug it in with a fresh set of batteries and check the circuit and a clock periodically, until the LEDs fade or start to act erratically.

Why is it so difficult to predict?

Digital LEDs seldom run in one fixed state — they’re usually animated. We can estimate the power use for a steady configuration, but animation is constantly in flux.

Also, battery manufacturers often overstate their cells’ capacity, or express it under extremely idealized circumstances.

Here at HitLights we sell battery packs to power our strips and LED products. They’re relatively simple, you charge them and plug them in, and your lights turn on! A little more complicated, however, is figuring out which battery you need, and how long it will power your lights for. 

Today, we’re going to figure that out.All of our strips draw a certain amount of Watts, or power, from either a power supply, or in this case, a battery. The capacity of batteries is measured in mAh (milliamp hours) or Ah (amp hours). One mAh is one thousandth of one Ah. The batteries we sell have a capacity of either 3500 mAh (3.5 Ah), 6500 mAh (6.5 Ah), or 20000 mAh (20 Ah). But how do they relate to Watts?

How long do led strip lights last?

You may have become drawn to LED strip lights because of their long lifetime claims. But how long do they actually last? How is lifetime defined? If you’re feeling skeptical, keep reading to find out how and when your LED strips may fail, and how manufacturers arrive at their lifetime claims.

LED lifetime and the 70% rule (L70)

Unlike incandescent bulbs which burn out and fluorescent lamps which begin to flicker, LEDs behave differently in that over time, they slowly and gradually lose their light output. Therefore, barring any “catastrophic” failures caused by things like power surges or mechanical damage, you can expect the LEDs on your LED strips to be usable until they are considered too dim for use.

But how dim is “too dim for use”? Well, there are as many answers as there are lighting applications. The industry, however, has somewhat arbitrarily decided that 30% light loss, or 70% of light remaining, should be that line in the sand. This is commonly called the L70 metric, and is defined as the number of hours it would take for an LED to diminish to only 70% of the original light output.

How long do led tea lights last?

Tea lights will burn for about 4 hours. If you want something that will burn longer, use votive candles. Depending on the size you get, votives will burn up to 10 hours. The biggest advantage to tea lights is if you leave them in the little tin or plastic cup, the clean-up is a lot easier.

Well the cheapo ones you get at walmart burn about 2-3 hours.They do have different kinds that burn for like 5-6 hours you can probably find online.If you need a tealight to burn a long time,I would recommend soy candles.I make soy candles and I can tell you that they burn a lot longer than parrafin wax candles do.

I usually get the votives in the glass holder from Big Lots that are 12 in a package for $6 and they last from 4-5 hours. I use these with my catering job. The ones from Michae’s that are a bit more expensive last the same.

How much longer do led lights last than incandescent?

Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years.

Even the cheapest LED light bulbs (Philips sells some for as low as $2 per bulb) claim to have a 10-year lifespan, but it’s important to know that’s actually based on some pretty modest assumptions. If you read the fine print (notice the asterisks next to the 10-year claim in the image above), a 10-year lifespan is based on only having the bulb on for three hours per day, every day. In some households, this can be accurate, but in others, that’s laughable.

This particular 10-year claim means that the LED bulb can last for nearly 11,000 hours. So if we were to have the bulb on for eight hours every day (two hours in the morning and six hours in the evening, for instance—possibly longer on the weekends), this means that it would only last shy of three and a half years.

Compared to an incandescent light bulb that has an average 1,000-hour lifespan, 11,000 hours is still way better, but don’t let the 10-year claims fool you. Plus, there are plenty of other factors to keep in mind.
