There are a number of basic reasons for LED lights to fail but the primary issue is heat. Over-heating can be a result of a number of design and assembly issues but is still the cause of the majority of LED lamp failures – both in the fitting themselves and also the drivers.
Turning the light on and off over time results in the thermal expansion and contraction of base material, and can cause LED solder joints to fail. When an LED bulb loses 30% of its brightness, it is considered to be at the end of its useful life.
Unlike incandescent light bulbs, LEDs don't produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
Reasons often include a faulty power supply, loose connections, a faulty circuit design, or even damage due to water ingress caused by rain. Whatever the reason is for your LED lights not working and whatever the tell-tale signs are, there's usually a solution to the issue.
Electrical leaks, short-circuits and electrical leaks that involve short-circuits are some of the more likely faults that occur in LED devices. Unlike faults in conventional incandescent and fluorescent lights, these faults involve short-circuits and can place a burden on the drive circuit.
While incandescent light bulbs were built to last around 1,000 hours, the most enduring LED light fixtures have been tested to last as long as 100,000 hours. On average LED light bulbs will not have to be changed for at least 20 years.
LED bulbs afford in the region of 50,000 hours of light, with some brands boasting as many as 100,000 hours. In general, terms, if you use your lights for 10 hours each day, LEDs should serve you well for just shy of 14 years.
But most commonly, LED bulbs may flicker or dim in your home when there are voltage fluctuations in your home's wiring. When electrical loads turn on and off in your home, this creates a change in voltage levels, which may cause the LED lights to occasionally dim or flicker.
A great benefit to LED bulbs is you can repair almost everything. Premature burnouts can be caused by poor component quality, LED overheating, and voltage jumps. The good news is that you don't have to have a lot of experience to handle the repair and the cost is significantly less than the price of a new bulb.
An LED light's bulb case temperature is also a crucial factor affecting its lifespan. Temperature higher than 85 degrees is bound to shorten light's lifespan. If the bulb case temperature reaches higher than 105 degrees, the light stops functioning.
A: LED lights are known for their long lifespan, with many manufacturers printing the expected life directly on the packaging. This can range from 5 to 20 years, but there is more to the actual life of an LED than a simple manufacturer estimate.
Over time, this filament gets hotter, weaker and eventually burns out. LEDs, however, do not contain a filament and instead illuminate using a semiconductor. So instead of just instantly burning out like traditional bulbs, LED lights age over time and progressively get dimmer until they stop working altogether.
Using a dimmer to keep your LEDs lit will increase their lifetime hours. An average LED bulb without dimming capabilities will last around 40,000 hours. By dimming the light using either of the above two methods, you're essentially extending its Average Rated Life (ARL).
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 20,000 - 25,000 hours.
LED light bulbs flicker when the frequency is lower than 50Hz. LED light bulbs may also flicker if the wiring is incorrect or loose. Another reason is incompatible dimmer switches. Last but not the least, a problem with one or more LED bulb components, like a faulty LED driver, may also cause flickering.
A “bad” or failed LED driver will stop transmitting power, causing your LED array or fixture to go out or fail to turn on the next time you try.
Incandescent light bulbs have an average lifespan of 1,000 hours, meaning they last around one year. With an average lifespan of 25,000 hours, a Philips Hue light bulb will not need replacing anywhere near as often.
Most LED bulbs boast a lifespan of up to 50,000 hours, which means that you may not have to splash out on LED replacement bulbs for up to 10 years after your original purchase. Incandescent bulbs and halogen bulbs will probably only last for 1000 - 2000 hours, compared to up to 100,000 hours for dimmable LEDs.
While incandescent bulbs typically last only around 1,000 hours - barely a year with several hours of use each day - LED lighting is commonly rated to last 50,000 hours or more, which can conceivably translate into decades at the same rate of use.
Integrated LED Fixtures: These LED fixtures may resemble LED ready fixtures, but the similarities end there. Integrated LED fixtures come complete with the LED arrays already built into the fixture. They are designed to provide a specific color and Lumen output and they do not have typical “bulbs” that can be replaced.
