Flickering of lights is not common. It happens when there is an issue with the light, wiring, holder, and other components. It’s an indication of a fault, which requires immediate attention. Let’s see the reasons behind the flickering of LED lights and how to fix them. We’ll also share some tips to prevent LED light flickering from happening. Are Flickering LED Lights Dangerous? Yes, flickering LED lights are dangerous. They could be an indication of a loose electrical connection or faulty wire that could lead to sparks and result in an electrical fire. Secondly, it raises health concerns, such as eye strain, headache, blurred vision, fatigue, etc. LED lights should offer even lighting without flickering. Why Do LED Lights Flicker? Here are some common reasons for LED light flickering. 🚫1. Loose Connection Often, LED light flickers because of a loose connection. The wire could be loose from the joint or connection. Secondly, the bulb could also be loose from the socket. In any case, you’ll see the flickering. It happens because of the interruption of the electric supply. The flow of current is disturbed because of the loose connection, and it causes frequent flickering. 🚫2. Voltage Fluctuations The second common reason is the fluctuation in voltage. All electrical devices, including LEDs, have a rated input voltage. If the voltage is low or high, it won’t light up properly or may even get damaged. If the voltage fluctuates abruptly, this sudden change could cause flickering. You need a stabilized voltage for LEDs to work properly. 🚫3. Faulty Wire/Device The wires carry current to the LED light. If they are damaged at any location, the flow of current will be affected. It will generate sparks and pose a fire hazard. Another reason could be a faulty device. If the device has any faulty LED SMD or component, it will not light up properly and cause flickering. 🚫4. Dimmers LED lights do not require a dimmer, and often, they are not compatible with it. However, some people already have dimmers in their houses to control the light. Due to incompatibility, LED lights would flicker. The function of a dimmer is to change the resistance, which alters the flow of current and controls the brightness. But LED lights do not support this and start flickering. 🚫5. Inrush Current The inrush current of high-power appliances also causes LED lights to flicker. When you turn on a water pump or any other heavy appliance, the voltage drops, and the light starts to flicker. However, it is temporary because the inrush current lasts only for a few seconds, and then everything gets back to normal. How to Fix Flickering LED Lights? Let’s check some common ways to fix the flickering of LED lights. 💡Fix 1: Tighten the Connection Check for the loose connections around the holder. Make sure to turn off the power supply in the first place. If there is any loose connection, tighten it properly. You need to tighten the screw terminals to ensure smooth flow of the current. Often, the joints are not properly twisted and are covered with insulation tape. If the holder is faulty or loose, you need to replace it. The LED light should be fixed properly, and any loosing will cause flickering. 💡Fix 2: Replace the Light Often the main culprit is LED light. You can check it by installing it in other rooms. If it flickers there as well, it means you need to replace the light. It usually happens when you use a low-quality LED light or if the light is about to complete its lifespan. 💡Fix 3: Change Wiring If the wiring is too old and there are signs of fraying and sparks, it is better to get it changed as soon as possible. In this case, you should hire an experienced electrician and get the faulty wires replaced. If all the LED lights on the circuit are flickering, it is a clear indication of faulty wiring or components. It requires an electrical audit. 💡Fix 4: Remove Dimmer If there is a dimmer controlling LEDs, remove it. Use the light without any dimmer as most lights do not work with them. And if you really need to use a dimmer, use a compatible one that is specifically made for controlling LEDs. However, it is not recommended. 💡Fix 5: File a Voltage Fluctuation Complaint If you notice voltage fluctuations, you can file a complaint. Inform the distribution company about the issue. They will check from their end and resolve the issue. If the issue still persists, it means that there could be an issue with the circuit breakers, wiring, etc. Learn more about why light bulbs burn out Preventing LED Flickering Before It Starts You can prevent LED lights from flickering. Here’s how: Always go with certified and reputable LED light brands. Make sure the light is certified by UL, ETL, CSA, CE, Energy Star, etc. If you have no idea or experience in handling electrical installation and the task is complex, it is better to consult an electrician. Install surge protectors in your home or office. It protects from power spikes and ensures a smooth supply of electricity. Always use the same LED brand and model on the same circuit. They work seamlessly without any issues. Do not use dimmers, and if required, use LED-specific dimmers only Keep the fixtures clean to prevent them from overheating Flicker-free LED Bulbs Recommendation-Govee Govee offers flicker-free LED bulbs that are made from quality components and materials. The LED bulbs are not only flicker-free but also smart. You can adjust the brightness, color, effects, etc. There is no need to use dimmers. You can group multiple bulbs and control them through your smartphone or voice. See all smart LED bulbs > FAQs about LED Light Bulb Flickering 1. Do flickering lights indicate an electrical problem? Yes, the flickering of lights often indicates an electrical problem. There could be a loose connection, faulty light, wiring issues, etc. 2. Do LED lights flicker before they burn out? Yes, flickering can be a sign of a faulty light. Usually, LED lights flicker before burning out. 3. Is a flickering LED a fire hazard? Yes, flickering LED lights could be a fire hazard. There could be sparks due to a loose connection, frayed wiring, or faulty bulb. Conclusion LED lights do not flicker without any issue. If there is any flickering, you need to find the root cause and then fix it. It indicates a fault, which could be a fire hazard as well. If you notice LED flickering, try to get it sorted as soon as possible. Consider the fixes we have shared, and in the first place, try to avoid flickering before happening.
