Are your recessed lights flickering? At best, this can be annoying. At worst, it can be dangerous.
While your first thought may be that this is some kind of bulb issue, recessed lights are not like standard fixtures, and it’s likely that this is not the problem. The guide below will explain the causes of flickering lights, how dangerous the situation may be and what you should do next.
Quick Takeaways
- If your recessed lights are flickering, it’s probably a wiring, connection or compatibility problem.
- LED bulbs are incompatible with some dimmer switches.
- There may be a fire risk if wiring is loose.
- Heat buildup in recessed fixtures makes flickering problems worse.
- Contact a licensed electrician if the flickering continues.
What Flickering Recessed Lights Mean
When your recessed lights are flickering, this indicates an electrical current that is interrupted or unstable.
The fact that these lights are recessed makes them more sensitive than surface-mounted lights. Because they are set into an enclosed area, they have a tendency to trap the heat that the bulbs create. If the bulbs use LED chips, those chips are sensitive to heat, and this could cause flickering and failure.
In addition, recessed lights are more complicated to install, which means that there are more opportunities for installation errors.
Recessed lights may occasionally flicker because of a power surge. A persistent flicker is more reason for concern and can have a number of different causes.
Common Reasons Recessed Lights Flicker
Recessed lights may flicker because of problems with the wiring, the switch or the electrical panel.
1. Loose Bulb or Socket Connection
This common cause of flickering lights can happen when vibration or heat loosen recessed sockets. Older recessed lights are more vulnerable to this because the effects of vibration or heat can build up over time.
2. Incompatible LED Bulbs and Dimmer Switches
LEDs operate using a different technology than incandescent bulbs. In addition, they’re more sensitive to changes in voltage. You need a dimmer switch that is compatible with LED bulbs.
This incompatibility may be the issue if the lights don’t respond properly to the dimmer switch. For example, they might dim or brighten suddenly instead of gradually.
3. Overheating Inside the Recessed Housing
Heat that would dissipate on standard fixtures builds up inside the recessed housing.
In addition, older fixtures may not be rated for contact with insulation. Insulation added at a later time could then lead to overheating.
4. Loose Wiring in the Fixture or Ceiling
When wiring is loose, the electrical current is intermittent. This can lead to flickering.
“Arcing” occurs when electricity jumps between loose wiring connections. Arcing may create sparks that can start a fire.
5. Voltage Fluctuations or Circuit Load Issues
When appliances start up, there is an initial surge in voltage to the appliance and a drop to other items. This can cause lights to flicker momentarily.
Lights may also flicker more frequently if they share the same circuit with too many other appliances, particularly large ones.
6. Aging or Failing Recessed Light Fixtures
The internal components of recessed light fixtures wear out over time. When this is the case, it may be necessary to replace the entire fixture.
When Flickering Recessed Lights Are Dangerous
If any of the additional factors below are present, the flickering could be a safety issue:
- Buzzing
- Burning smells
- In multiple rooms
- Gets worse over time
Arcing can cause a buzzing noise, while a burning smell can indicate that insulation is burning. When the flickering is in multiple rooms, it suggests that the problem may be at the electrical panel rather than the individual fixtures.
Both wiring and panel issues can cause flickering that worsens over time.
What You Can Check Safely — and What You Shouldn’t
DIY that involves electricity can be dangerous, but you can check bulb tightness on your own. You can also see whether the flickering is connected to your use of the dimmer switch.
For anything else, you need an electrician. This includes examining wiring, housings and junction boxes.
When it comes to recessed lighting, a professional is particularly important. Because the lights are set into the ceiling, wiring and other potential problems may be concealed.
How Electricians Fix Flickering Recessed Lights
Depending on what the issue is, there are several remedies an electrician may use to fix your lights.
They will inspect the fixture and the wiring. If necessary, they may replace the fixture and stabilize the wiring or repair loose connections.
An electrician can also check your dimmer switch for compatibility and upgrade it.
If the issue is with your circuit load, a professional can redistribute fixtures, outlets or appliances to other circuits.
Proper installation of recessed lights prevents flickering. A professional can ensure that the lights are distributed appropriately across circuits. They will also make sure connections are safe and that switches are compatible.
Code-compliant installation checks can ensure that your recessed lighting is both functional and safe.
Preventing Recessed Light Flickering in the Future
Understanding the causes of recessed light flickering helps you avoid it.
Making sure you have compatible dimmer switches, ensuring that circuits aren’t overloaded and getting fixtures that are rated for insulation contact are important.
In addition, if your lights are old, it may be necessary to replace the housings altogether. You can schedule a professional inspection if you aren’t sure whether your lights are safe or code compliant.
FAQ: Recessed Light Flickering Questions
We’re eager to answer your questions about recessed light flickering, including the common ones below.
Why do my recessed LED lights flicker randomly?
Your lights may flicker for several reasons, including loose connections, age, overloaded circuits or an incompatible dimmer switch.
Can flickering recessed lights cause a fire?
If the flickering lights are accompanied by a buzzing sound or a burning smell, they could cause a fire. There may also be a fire hazard if the flickering happens in multiple rooms or is getting worse.
Do recessed lights flicker more than regular lights?
Recessed lights may be more vulnerable to flickering because their placement can hide problems or cause heat to build up and degrade connections.
Why do my recessed lights flicker when appliances turn on?
There may be a temporary drop in voltage to the lights and a surge to the appliance as it turns on.
Should I replace the bulb or the entire recessed fixture?
It depends on the type of bulb and the nature of the problem, but if the fixture is old, it may be necessary to replace the entire thing.
Is flickering a sign of bad wiring?
Bad wiring is one cause of flickering, but lights can flicker for other reasons as well, including circuit overloads and problems with the switch. An electrician can determine what’s causing the flickering.
