Why do LED lights still glow when off?
In contrast to incandescent bulbs or halogen lamps an LED lamp has a high resistance due to the integrated power supply unit. The serial connection of the glow lamp closes the circuit even when the switch is turned off. As a consequence a low voltage drop appears to the LED driver so the LED still lights up weakly.
Why do my LED lights come on by themselves?
They do not normally turn on by themselves. If they loose power…they will immediately turn on when power is restored. This happens even when the lights are powered off but still connected to a live power source.
Why do my LED lights turn off randomly?
If your lamp has a confined space, or if it is a downlight with no ventilation, it can capture heat (heat rises) and the heatsink will not cool properly. Better LEDs have thermal detection and will shut off to spare the LED emitter from overheat.
What can go wrong with LED lights?
Most Common Problems with LED Lights
- Using the wrong current.
- LED bulbs overheat.
- Low quality solder and wire bonds.
- Improper use of LED lighting.
- Issues with color rendering.
- Existing fittings and fixtures are incomparable.
- Light Emitting Efficacy.
- Overly complicated circuits.
How do you tell if an LED bulb is going bad?

How do you know when an LED bulb is going bad?
One of the most common problems when using LED is the light flickering. The lights are basically strobing. If you are using poor quality LED bulbs or flood lights, then you will observe the brightness goes up and down rapidly. If the flicker frequency is below 80 to 100 Hz, then it can be observed by naked eyes.
Can LED lights be fixed?
YES. Unlike traditional incandescent bulbs, modern LED bulbs allow for almost everything to be repaired. What you need to do is to find out the problem and take reasonable action to repair, or replace some damaged parts of the LED bulb, your lamp can work properly again.
Do LED lights 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 long do LED lights last?
One of the biggest advantages of LED light fixtures, is their extended lifespan. 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.
When Should LED bulbs be replaced?
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.
Why do my LED lights burn out so fast?
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!
Do LED lights have to be replaced?
With LED lights, though, they don’t necessarily “burn out.” Instead, they fade or dim until they no longer produce enough life for your taste. So, when the light in your home becomes too dim, it’s time to replace them.
Do you need a special switch for LED lights?
While many LEDs today are dimmable LEDs (not all are) you should still use a special dimmer switch for LED lights in order to avoid some of the common problems associated with incompatible dimmers.
Can I use my old dimmer switch with LED bulbs?
A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.
How long do non replaceable LED lights last?
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.
