LED lights are becoming a popular option for those seeking energy-efficient, long-term solutions. But before making a purchase, it's common to ask yourself, “Do LED lights burn out?” The good news is that with proper care and maintenance, LED lights can last for many years without problems.

Although, over time, their brightness will eventually fade away, LEDs don't typically burn out the way more traditional light sources do. In this blog post, we'll explain why LED lights don't burn out, outlining the key benefits of investing in these durable bulbs.

Part 1. Do LED Lights Burn Out?

Do LED lights burn out? This is one of the most frequently asked questions regarding LED lighting technology. The simple answer is no. Over time LED lights will eventually fade away, but they don't burn out. However, they typically last longer than traditional incandescent bulbs and other lighting options.

Incandescent bulbs use a filament that gradually evaporates over time, resulting in them having only a 1,000-hour lifespan on average before burning out completely. On the other hand, LED bulbs boast better longevity. They use semiconductors to convert electricity efficiently into visible light while minimizing heat and wear and tear, making them highly reliable.

One important factor in the lifespan of an LED light is the L70 standard, which is used to determine when an LED light has reached the end of its useful life. By international standards adopted by most certifying agencies, an LED light is said to have gone bad when its light output depreciates to 70% of the original/new rated output. This is referred to as the L70 measure or specification of the LED light. The longer the L70 number in hours, the better the life of the LED light. As long as it is working within its expected parameters, it can still be used for a certain period of time before being replaced.

Part 2. Do LED Lights Lose Brightness Over Time?

When you invest in LED lights for your home or business, the first thing you have in your mind is do LED lights burn out, and the last thing you want is for them to lose their brightness over time. However, this is a natural process known as lumen depreciation or lumen degradation. Over time, the amount of light produced by an LED light will decrease, eventually reaching a point where it is no longer as bright as it once was.

The rate of lumen depreciation can vary depending on factors such as the quality of the LED and its operating conditions. It can also happen due to gradual or catastrophic failure, which can be caused by various factors such as defects in the material, high current, or stress from thermal expansion.

Most manufacturers define the lifespan of an LED lamp as the time at which its output luminous flux drops below 70% of its initial value. The quality of the material used for manufacture directly impacts performance and lifetime; defects in the material may result in nonradiative decay leading to a reduction in output from the lamp.

The high current and thermal expansion stress could damage components within, causing unrecoverable breakdowns, ultimately compromising output and lifetime too! Epoxy encapsulation usually helps protect the die within, but when moisture and caustic chemicals seep-in due to inappropriate encasing techniques, shorts or voltage spikes are possible, making LEDs vulnerable to high-voltage electrostatic discharge resulting in complete failure!

Hence, proper care should be taken while selecting LED lamps to offer maximum luminescence even during prolonged usage!

Part 3. How Long Do LED Lights Last?

So, having learned about do LED lights burn out and do LED lights lose brightness over time. Now let's discuss how long do LED lights last.

Type of Bulb Average Lifespan
Incandescent 1,000 hours
Halogen 2,000 hours
Compact Fluorescent (CFL) 10,000 hours
LED 25,000 ~ 50,000+ hours

One of the main advantages of LED lights is that they have a much longer lifespan than traditional incandescent and halogen bulbs. Whereas these older forms of lighting typically last only 1,000–2,000 hours before needing to be replaced, LED lights can last 25,000 to 50,000 hours or more—a remarkable difference!

This means that an LED light bulb can remain in use for years without being replaced—all while using significantly less energy than other bulbs. Such an advantage drastically reduces maintenance costs over time since there's no need to purchase new bulbs or install replacements continually.

Part 4. Common Problems with LED Lighting

Failure to Follow Current or Voltage Recommendations

LEDs require a specific current and voltage to function correctly, which means you need the right power supply (e.g., transformer) for your lights’ wattage rating. If you fail to deliver the right amount of current or voltage, your LED bulbs may not turn on at full brightness. To avoid these problems, make sure you use the recommended power supply for your LED bulbs and check that it matches the wattage rating of your lights before installing them.

Cheap or Low-Quality LEDs

Low-quality LEDs may initially appear cost-effective but often result in increased maintenance costs and decreased product life expectancy due to reduced light output. To guarantee reliable performance, consider products certified by reputable organizations such as those with Energy Star approval from the US Environmental Protection Agency (EPA).

LED Lights Flickering

Flickering is also one of the common problems with LED lighting that is often caused by voltage fluctuations or by using an incompatible dimmer switch. If you find that your LEDs are flickering, try using an LED-compatible dimmer switch if possible - this should solve the issue. Alternatively, check wiring connections to ensure they're tight and secure before purchasing a new switch.
