Top Reasons Why Dimmable LED Flash and Flickering
1. Incompatible Dimmer Switches
The use of incompatible dimmer switches is the main reason for dimmable LED flash and flickering. Not all dimmer switches are made to operate with led lights. LED lights need a dimmer switch which is certainly mentioned with features of LED technology compatibility. The use of incompatible dimmers can results in voltage variations then result in the flickering and flashing
2. Overloaded Dimmer Switches
Dimmer switches have a wattage rating, indicating the maximum load they can handle. Overloading a dimmer switch by connecting too many LED lights or other fixtures exceeding its capacity can result in flickering or flashing. It is crucial to ensure that the total wattage of the connected lights does not exceed the maximum rating of the dimmer switch.
3. Inadequate Power Supply
The ineffective power supply can help cause dimmable LED issues. When the power supply is not stable or does not provide a certain current to the LED light, they face flicker issues. It causes due to wiring issues, loose connections, or faults with the electrical panel. Finding the faults in the power supply is important to resolve the flashing or flickering.
4. Poor Quality LED Lights
Low-quality led lights can cause different problems with flickering and flashing. Improper structure of LED lights can have not properly configured inner components or causes heat dissipation, which results in the light flashing or flicker. So must use accurate quality LED lights from famous brands
5. Voltage Fluctuations
Voltage variation in the electrical system can result in dimmable LED lights flicker. These variations can be caused due to different reasons, like appliances turning on or off, power grid problems, or electrical malfunctions. Voltage stability helps to reduce flickering issues

2. Reduce the Load on Dimmer Switches
If there are many leds lights or other devices with a single dimmer switch. Then reduce the load by removing some lights or distributing the load to other switches. Make sure that the total watts of connected lights are not larger than the maximum rating of the dimmer switch
3. Ensure Sufficient Power Supply
Monitor your electrical system and wiring to make sure accurate and stable power supply to LED lights. Find if there are any loose connections, wiring problems, or faulty panels.
4. Invest in High-Quality LED Lights
The use of quality LED lights from famous manufacturers can decrease the flashing or flickering issue. Sue such LED lights that have faced many tests and are famous for their reliable operation. They can be a higher cost but work longer duration
5. Stabilize Voltage Fluctuations
To find the voltage variations check the voltage stabilizer or surge protector. These devices help to regulate the voltage provided to the system, making sure the stability of the supply to LED lights.
Use dimmable power supplies.
- If LED lights are not dimmable they cause flickering when you will dim them. Use a dimmable power supply to make sure lights will dim smoothly and uniformly.
Use PMW LED power supplies.
- PWM full form is pulse width modulation and a type of dimming technology used with led lights. PWM dimming offers smooth and consistent dimming features than another dimming to reduce the flickering
Check compatibility between the light and the controls.
- Not all dimmer switches have compatibility with each other. Ensure that the light and dimmer switch you have to use must be compatible to minimize the chance of flickering
Use an LED-sensitive dimmer switch
- Sensitive dimmers are specially made of these LED lights. They provide smooth operation and flicker-free dimming features than other dimmers
Is the dimmer switch in programming mode?
- Some dimer switches come with programming mode which results in flickering. Ensure The dimmer switch is not in programming mode before connecting to the light
Are you dimming the wrong type of LED?
- Not each LED light is dimmable. Ensure that the LED lights that you used are dimmable before dimming them
Have you exceeded the maximum quantity of LEDs?
- Dimmer switches provide the highest load capacity. if you cross the load capacity, the dimmer switch start flickering. Ensure ath you did not exceed the maximum load cacpity of the dimmer switch
Has the dimmer switch been de-rated when choosing?
- Dimmer switches can be derated during selection. It means that the dimer switch is not able to handle complete loads of LED during operation. Ensure that the dimmer switch is not rated before you connect with the lights
Is the LED driver too small?
- The led driver is an element that provides the power to led lights. If the Led driver is small size, it can not be able to offer enough power to that cause flickering. Ensure the LED driver is the proper size for led lights
Are you meeting the minimum load?
- Some dimmer switches needed less load to work accurately. If you’re not fulfilling the minimum load, the dimmer switch can start flickering. Ensure that you are fulfilling the load needs of the dimmer switch
Is dimmer light flickering on low?
- Some dimmer switches can flicker when they are dimmed to fewer values. It is generally due to the dimmer switches working techniques. If you are facing flickering at low levels you can need to use differnt dimmer switches or wireless dimming
Try wireless dimming.
Wireless dimming is the dimming type that uses radio waves to control dimmer switches. it can help to decrease flickering as there is no electrical connection between the dimmer switch and the light.
Buy good quality products.
- Still, you have to flicker after using the different solutions above mentioned, and not have to use quality products. There are differnt brands of LED lights and dimmer switches on the market and some are good quality. If you get quality products you are less chance to have to flicker
Dimmer switch overheating.
if the dimmer switch is overheating it can start flickering. Ensure that the dimmer switch is not overheating before connecting to the lights
Test with mock-ups.
There is final option is to use mock-up testing. It means that make a small circuit which led lights and a dimmer switch to check that you replicate the flickering. If you can replicate flickering can start finding the issues
