The most common reasons for LED blowing out are high voltage, bad contacts, use of incompatible dimmer switch, or recessed lighting. Other causes include overheating due to not using the right fixtures, or simply a bad batch of lightbulbs!
Why do my LED bulbs burn out?
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.
How do you fix a LED light that burns out?
How do you fix a LED light that burns out?
- Step 1: Disassemble the Bulb. First cut the top of the bulb off.
- Next locate the offending LED. it will have a faint dark spot as compared to the other LED’s.
- then just solder the connection under where the LED was to bridge the connection and you are finished.

Why do LED bulbs fail so quickly?
Temperatures are too high (or too low)
When heat can’t dissipate from the heat sink, it can cause lamps to fail prematurely. Also keep the surrounding environment in mind. … Because LEDs emit light that decreases exponentially as a function of time and temperature.
How long do LED light bulbs really last?
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.
How do you stop an LED from burning?
Resistors in Light Emitting Diode (LED) Circuits
Such a resistor is often called a ballast resistor. The ballast resistor is used to limit the current through the LED and to prevent that it burns. If the voltage source is equal to the voltage drop of the LED, no resistor is required.
How can you tell if an LED bulb is blown?
2 Answers. It’s an LED. Easiest way to see if it is damaged is to connect it to a battery and see if it lights up. The difficulty is that you can’t disassemble the the white plastic unit, so if the LED does not light, the connection wires, resistor or LED itself may be damaged.
How do I know if my LED drivers are bad?
LED drivers rectify higher voltage alternating current to low voltage. If you have a good LED and a bad operating LED driver your high bay LED Lights won’t be functional for long. Most LED failures are not from the LED, but from the driver. Usually the circuits burn out and fail.
Can LED lights be fixed?
A LED light bulb is a modern and efficient light source. … Traditional incandescent light bulbs cannot be repaired at all, while in LED bulbs you can repair almost everything. You just need to find the malfunction, make some repair and prolong your light bulb lifetime.
Is LED light bulb good for eyes?
The “blue light” in LED lighting can damage the eye’s retina and disturb natural sleep rhythms, France’s government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness. …
Can you touch LED bulbs with your hands?
Since LEDs produce light through electroluminescence rather than heat, it is fine to touch them with bare hands. That being said, it’s best not to handle them any more than absolutely need to.
Can LED lights catch on fire?
LED lights do not emit light from a vacuum as most other bulb types do. … Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly lower temperature than other bulbs.
Is it safe to leave LED lights on all night?
Can you leave them on overnight? Yes, LED lights are ideal for leaving on for long periods of time due to their low power usage and very low heat output. They are more suited to use as a night light/ background accent light in general.
Is it better to leave LED lights on?
The operating life of a light emitting diode (LED) is unaffected by turning it on and off. While lifetime is reduced for fluorescent lamps the more often they are switched on and off, there is no negative effect on LED lifetime.
When Should LED bulbs be replaced?
First of all, rest assured that the average LED bulb will produce 60% of its power (easily enough due to its powerful shine) for 50,000 hours before giving up the ghost. This means that you will only need to replace an LED bulb, depending on the usage it receives, every 5 – 10 years on average.
