<h2><strong>Introduction</strong></h2>
Most people get worried and fret over lights flickering suddenly out of nowhere. It’s not always due to damage in the electrical circuit or fluctuating power input from the local supply. Rather, several other reasons can also lead to flickering bulbs and tube lights. Knowing these can help you in electrical troubleshooting with urgency, especially if receiving help from a professional electrician isn’t feasible at that moment. With this being said, we have illustrated the top ten events that lead to flickering lights and their solutions.
<h2><b>Loose light bulb or connection</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">A loose connection is often the culprit behind </span>lights flickering<span style="font-weight: 400;"> occasionally. It’s because the bulbs do not receive proper electrical supply due to the faulty connection, and hence flicker.</span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">Turn off the light and wait for a couple of minutes for the bulb to cool down. Once cooled, check if it's screwed in properly. Also, ensure the fixture is correct for the bulb type. </span>
<h2><b>Faulty light bulbs</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">Sometimes, </span>faulty light bulbs<span style="font-weight: 400;"> can flicker occasionally as the internal circuits fail to maintain proper electrical flow. Damaged terminals, broken filaments, or reduced internal gas pressure are some of the reasons for faulty bulbs. </span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">If the light bulbs are damaged, it’s better to replace them with new ones so that you won’t have to deal with </span>lights flickering<span style="font-weight: 400;"> again. </span>
<h2><b>Power fluctuations</b></h2>
<h3><b>Why it happens?</b></h3>
Flickering lights often happen due to power fluctuations across the end terminals. LED bulbs are quite sensitive to the slightest deviation in the input power. Old incandescent bulbs also flicker when they are near the end of their lifespan.
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">Upgrading to newer and modern bulbs can help resolve </span><b>lights flickering</b><span style="font-weight: 400;"> due to power fluctuations.</span>
<h2><b>Major applications turning on/off</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">Sometimes, turning on or off major appliances like refrigerators and air conditioners can cause the lights to flicker due to voltage changes or momentary electrical disruptions. </span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">The best </span><b>electrical troubleshooting</b><span style="font-weight: 400;"> method will be to check the maximum load capacity of the terminals and get help from a professional electrician. </span>
<h2><b>Loose or faulty wirings</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">Loose or </span>old wires<span style="font-weight: 400;"> fail to maintain a consistent electric supply to the bulbs, causing them to flicker. If not addressed immediately, it can lead to fire hazards. </span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">Check if the wires are loosely connected or not after turning off the electrical supply. If they are loose, tighten the wires. For replacing old wires with new ones, you may need the help from an electrician. </span>
<h2><b>Dimmer switch incompatibility</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">Sometimes, </span><b>dimmer switch problems </b><span style="font-weight: 400;">can also cause the connected bulbs to flicker. That’s because the chosen dimmer is not compatible with the electrical fixture and fails to control the bulb’s brightness.</span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">While purchasing the dimmer switch, check if it's compatible with the light bulb and the electrical fixture to avoid flickering issues. </span>
<h2><b>Not all bulbs are dimmable</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">One of the most common causes of </span><a href="https://ajv-tech.com/lighting-design">lights flickering</a><span style="font-weight: 400;"> is the use of dimmer switches with bulbs that are not dimmable. </span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">Check if the bulb is dimmable or not through an external device. If not, it’s better not to connect a dimmer with the same electrical fixture controlling the light. </span>
<h2><b>Check the dimmer switch wattage limits to avoid flickering</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">Using a bulb with power requirements higher than the maximum wattage limit of the dimmer switch can also cause it to flicker the moment you turn on the switch. </span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">Check the power requirements of the bulb and the maximum wattage limit of the dimmer switch before making the electrical connection between them. </span>
<h2><b>Overloaded circuit or panel issues</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">Another reason of flickering light is </span>circuit overload<span style="font-weight: 400;">. It happens when you connect too many appliances and devices with a single circuit and the power consumption exceeds the maximum wiring limit. </span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">Upgrade the electrical circuit to accommodate all the devices running simultaneously on the same wiring connection. </span>
<h2><b>Power grid or utility issues</b></h2>
<h3><b>Why it happens?</b></h3>
<span style="font-weight: 400;">If there is any issue with the utility services, </span>power surges<span style="font-weight: 400;"> will be a common occurrence. This can lead to occasional flickering of the bulbs connected to the supply line.</span>
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">Connect with your electric service provider to know if there is any issue with the grid or the power supply. If there is any issue, turn off the bulbs for the time being till the problems are resolved.</span>
<h2><b>Problems with local power supply</b></h2>
<h3><b>Why it happens?</b></h3>
One of the most common causes of lights flickering is underlying issues with the local power supply. Fluctuating voltage, loose service cable connection, and increased power consumption on the main line can be the cause.
<h3><b>How to fix it?</b></h3>
<span style="font-weight: 400;">If there is any problem with your local supply, call for professional help immediately.</span>
