How Long Do LEDs Last?

By LED Lighthouse

LED lights are not only highly efficient compared to other lighting technology, they also last a lot longer. For instance; the average life of a halogen 50-watt bulb is between 1,000 and 2,000 hours, approx. 1-2 years on average. The average life of most of our LED lighting is 50,000 hours, approx 50 years (of average usage).

The average life of most of our LED lighting is 50,000 hours, approx 50 years (of average usage).

Although LED lighting is relatively expensive initially compared to traditional lighting, the savings in just replacement bulbs alone usually covers the cost of the LED bulb itself. Then there’s the convenience of not changing a bulb for at least 30 years. Considering our LED bulbs will then use around 10% of the energy consumed by halogen/filament bulbs the savings soon add up over the bulbs’ lifetime.

How is the life of an LED defined

You might assume that once an LED bulb approaches 50,000 hours of use it simply burns out like incandescent bulbs. However, this is not the case.

There is no set way to define the lifespan of an LED just yet. That’s because LEDs do not burn out like incandescent bulbs (although sudden failure can occur, its extremely rare). Instead, their brightness slowly fades. So, if the lifespan of an LED is 50,000 hours, that is the point when the bulb will most likely be shining at around 70% (the industry assumes people notice a decrease in brightness at that point).

Important factors affecting the life of LEDs

Operating at a high temperature, usually above 60°C can shorten the lifespan of LEDs while also decreasing efficiency. In fact the colder an LED operates the more efficient and longer-lasting it becomes (down to -30°C). Therefore when choosing an LED bulb an important consideration is how well the bulb dissipates heat away from the LEDs. Aluminium bulb housings with fins usually help. The larger the housing, the more fins, the better the heat dissipates. That’s why as the power/wattage of an LED bulb increases, the bulb housing generally becomes larger.

Fluctuation in the supply current can damage LEDs, shortening their lifespan. Fortunately, most of our bulbs have built-in constant current chips safeguarding against this. In fact, all our 240V LED bulbs/fittings have a constant current chip. Most of our 12V bulbs/fittings have constant current chips; those that don’t can be powered by one of our 12V LED drivers instead of a standard 12V transformer.

RGBW vs RGB+CCT. Which is right for you?

At LED Lighthouse, we offer three different options depending on the requirements of your project: RGBW LED Strip – 60 LEDs per metre, 19.2W/m RGB+CCT LED Strip – 60 LEDs per metre, 19.2W/m COB RGBW LED Strip – 896 LEDs per metre, 16W/m All three allow you to combine colour-changing effects with dedicated white lighting, but there are some important differences between them. In this guide, we’ll explain how each type works and help you decide which LED strip is best suited to your installation.

A Complete Guide To Our LED Drivers And Power Supplies

When choosing LED strip lighting, most people spend their time comparing brightness, colour temperatures, or waterproof ratings. However, one of the most important components of any LED strip installation is the LED driver. Selecting the correct driver ensures your LED strips operate safely, achieve their full brightness, and provide years of reliable performance. Choosing the wrong driver can lead to flickering, reduced lifespan, overheating, or complete failure of the installation.
