We look at this subject in more detail asking What is Dimming? Methods for dimming LED lights LED Color Changing Problems Whether you’re using lights for your home or business, it’s important to be aware of this potential issue so that you can take steps to prevent it. If not any of these then an electrician may need to be called to diagnose and correct any underlying electrical issues. If you suspect that this is the case, stop using the lighting and contact the manufacturer for further instructions, mostly likely a replacement! This happens when the heat generated by the LEDs starts to increase exponentially, causing them to fail. Finally, if the LEDs are flickering or dimming intermittently, it could be a sign of thermal runaway.To avoid this issue, make sure to buy a dimmer switch that is specifically designed for use with LED lights and do not attempt to re-use an existing one. Older dimmer switches are designed for use with incandescent bulbs and will not work properly with LEDs. If you are using a dimmer switch, it may also be incompatible with LED lights.

Solution: Check the LED driver has the correct current or voltage for the light fixture. This can be caused by a faulty power supply or by using a lower-voltage power supply than what is recommended. Another possibility is that the power supply is not providing enough voltage or currrent to the LEDs.Make sure all of the wires are properly tightened before ruling this out. In some cases, it may be as simple as a loose connection.This can happen for a number of reasons, and it can be difficult to figure out what the issue is. One of the most frustrating things about LED lights is when they start to flicker or dim unexpectedly. However, some lights may not work with certain types of dimmer switches, leading to dimmable LED flash and flicker. Many homeowners are making the switch to LED lights, attracted by the promise of energy savings and longer bulb life. Troubleshooting the issue should help you get your light up and running again. If it has stopped working, it’s probably due to one of these reasons. Even though they are designed to last a very long time, they will eventually burn out. Finally, it’s possible that the light simply reached the end of its lifespan.
LEDs are sensitive to moisture and can be damaged by high humidity levels. Another possibility is that the light was damaged during installation or handling.Solution: Go over the whole installation to see if anything looks astray with the wiring, some of the solder joins are very small and susceptable. Loose connections, exposed wires, and other wiring problems can cause LEDs to fail. LEDs are also susceptible to power surges, so if there was a spike in electricity, that could have caused the light to fail.If the power supply fluctuates or isn’t strong enough, it can damage them. LEDs need a steadier, higher voltage power supply than incandescent bulbs. Solution: Plan in a maintenance schedule to change the fixture more regularly to avoid failure. If the fixture is exposed to extreme cold, the lifespan of the LEDs will be reduced, become fragile and fail early. LEDs are designed to run for their long lifespans when tested between specific running temperatures. Solution: Make sure the light fixture has air around it and is well ventilated.
LEDs create less heat than other types of light bulbs, but if the fixture is enclosed or otherwise not well ventilated, the heat can build up and cause the LEDs to fail prematurely. Solution: Make sure you’re using a dimmer switch that’s compatible with LEDs.
