Top 6 Causes of Tube Light Flickering

Do you have any idea why your tube light flickering? I have shortlisted some causes that will help you.

Loose Bulbs connection
  • Loose Bulbs: If your C9 Bulbs isn’t screwed in tightly, it flickers. Just tighten it up to fix this.
  • Faulty Electrical Connections: Lighting fixtures or wiring connections can cause flickering. These might need to be tightened or fixed.
  • Aging or Damaged Wiring: Damaged or old wires in your home can cause flickering lights. This usually needs a professional electrician to check and repair.
  • Overloaded Circuits and Voltage Fluctuations: Too many appliances on one circuit can overload it and flicker lights. Flickering may also occur if your home’s voltage isn’t steady. You might need to move some appliances to different circuits or talk to an electrician.
  • Faulty or Incompatible Dimmer Switches: Old dimmer switches might not work right with newer bulbs like LEDs, causing flickering. Switching to a dimmer switch that works with your bulbs can help.
  • Bulb Issues and Compatibility: Using the wrong type of bulb for your light fixture can flicker. Always use the right light bulb for each fixture, especially fluorescent lights.

Easy Guide to Fix: Flickering Tube Lights

Check and tighten the bulb.

The first step is to turn off the light. Fix the tube light securely in its socket.

Sometimes, a loose bulb is all it takes to flicker. Simply tightening it can solve the problem.

Inspect and Tighten Electrical Connections

You should turn off the power at the circuit breaker. Your flickering light could be a problem with its light switch, outlet, or wiring. Look for loose connections or wires. If you discover any, make sure they are tight.

Test and replace the tube

With the power off, remove the tube light and check for any darkened ends or visible damage. If the tube shows signs of wear or damage, change it.

If the tube looks fine, try it in a different fixture to see if it still flickers.

Evaluate the Dimmer Switch

If you’re connecting the tube light to a dimmer switch, check if the dimmer is compatible with the type of bulb you’re using. Flickering may occur with older dimmer switches and fluorescent or LED bulbs.

You might need to replace the dimmer switch with a compatible one.

Addressing Circuit Overload and Voltage Issues

If your flickering light problem happens when multiple appliances run, you might overload the circuit. Try redistributing your electrical appliances to different circuits. If you suspect voltage fluctuations, a voltage stabilizer might be necessary.

Consult a licensed electrician.

A licensed electrician is the best choice for complex issues like aging wiring and major voltage fluctuations. They can safely handle larger electrical problems and ensure your home’s wiring is up to standard.

If you follow these steps, you can diagnose and fix the most common causes of tube light flickering.

However, seek professional help for complex or potentially dangerous electrical issues.
