You just set up new LED lights in your garage. They looked great for about a week. Then the flickering started.
Sound familiar? You're not alone. Flickering LEDs are one of the most common lighting complaints in Australia. Garages, workshops, and sheds get hit the hardest because budget lights are usually the first thing people grab.
Here's the thing though. Most flickering problems are fixable. And once you understand the causes, you can dodge the issue entirely next time you upgrade.
What Actually Causes LED Lights to Flicker?
LED flickering happens when the electrical current flowing to the light isn't stable. Unlike old incandescent bulbs that just dim gradually, LEDs respond instantly to power changes. Even tiny fluctuations show up as visible flicker.
Let's break down the most common causes.
1. Incompatible Dimmer Switches
This is the number one cause. Most older dimmer switches were built for incandescent bulbs. They work by chopping up the electrical wave. Incandescent bulbs handle that fine because they're slow to respond. LEDs aren't.
When you pair an old dimmer with LEDs, the rapid on-off cycle creates a noticeable strobe effect. Sometimes it's subtle. Other times it's bad enough to give you a headache.
2. Loose or Faulty Wiring
Loose connections anywhere in the circuit can cause intermittent flickering. This includes the wiring at the light fitting, the switch, or even the main switchboard.
If the flickering comes and goes randomly, wiring is a likely suspect. This is especially common in older Australian homes where the wiring hasn't been updated in decades.
3. Cheap LED Drivers
Every LED light has a driver inside that converts your mains power into the low-voltage DC current the LEDs need. In cheap lights, these drivers cut corners. They use lower quality capacitors and less stable circuitry.
The result? Flickering that gets worse over time. We've seen budget hex lights from online marketplaces start flickering within a few months. The driver just can't hold up.

4. Voltage Fluctuations
In Australia, mains voltage sits around 230V as defined by the AS/NZS 3000 Wiring Rules. But it's not always steady. Large appliances like air conditioners, compressors, and power tools draw big surges when they kick in. That momentary voltage dip can make your LEDs flicker.
Garages and workshops are particularly prone to this. If your lights dim briefly every time the compressor starts up, voltage fluctuation is your culprit. We go deeper on brightness levels in our garage lighting lumens guide.
5. Overloaded Circuits
Running too many devices on a single circuit stretches the available power thin. Your LEDs might flicker when other equipment on the same circuit draws heavy current.
This is common in garage setups where the lighting, power tools, and maybe a fridge all share one circuit breaker.
How to Fix Flickering LED Lights
Now that you know the causes, here's how to tackle each one.
Check Your Dimmer Compatibility
If you're using a dimmer, try bypassing it first. Wire the light directly to the switch. If the flicker stops, you've found your problem. Swap the dimmer for an LED-rated one and you're sorted.
Inspect Your Connections
Make sure every connection point is tight and secure. For modular lighting systems like hexagon lights, check that each panel is firmly clicked into place. A loose connector between panels can cause individual sections to flicker.
Test on a Dedicated Circuit
If flickering happens when other gear runs, try plugging your lights into a different circuit. This isolates whether voltage drop is the issue. For permanent setups, it's worth getting an electrician to run a dedicated lighting circuit.

Upgrade Your Lights
Sometimes the fix is simple: replace the lights. If you bought budget LEDs and they're flickering after a few months, the driver quality just isn't there. Investing in lights with proper drivers saves you the hassle of repeated troubleshooting. If your workshop needs reliable overhead lighting, our workshop lighting systems are built with the kind of drivers that hold up long term.
Why Some Hexagon Lights Flicker and Others Don't
Not all hexagon lights are built the same. The market is flooded with cheap options that look similar on the outside but differ massively on the inside.
Here's a quick comparison of the key differences:
| Feature | Budget LED Drivers | Quality LED Drivers |
|---|---|---|
| Current regulation | Unstable, prone to fluctuation | Constant current output |
| Capacitor quality | Low-grade, shorter lifespan | High-grade, rated for 50,000+ hrs |
| Thermal performance | Overheats in plastic housing | Stays cool in aluminium housing |
| Flicker onset | Within weeks to months | No visible flicker over years |
| Connector design | Loose fit, intermittent contact | Reinforced snap-lock, stable contact |
| Typical warranty | 6 to 12 months | 3 to 5 years |
Here's what separates flicker-free hexagon lights from the rest:
- Quality LED drivers with stable current regulation, not the cheapest components available
- Consistent power delivery across every connected panel, so the last hex in the chain gets the same current as the first
- Proper thermal management through aluminium housing that keeps the driver cool and performing reliably
- Secure snap-lock connectors that maintain solid electrical contact between panels over time
At HexSpace, we've tested and refined our hexagon lighting systems to eliminate flicker at the source. Every panel runs through quality-controlled drivers. The aluminium body acts as a heatsink, keeping everything stable even during long sessions in the garage or workshop.
How to Choose Flicker-Free LED Lighting
Shopping for new lights? Keep these five things in mind.
1. Check the Driver Quality
The driver is the most important component for flicker-free performance. Look for lights that specifically mention stable current drivers or flicker-free operation. If the listing doesn't mention the driver at all, that's usually a red flag.
2. Look at the Housing Material
Aluminium housing dissipates heat far better than plastic. Heat buildup degrades drivers faster, which leads to flickering over time. If your lights will run for hours at a stretch, aluminium is the way to go.
3. Read Real Customer Reviews
Search for reviews that mention long-term use. A light that works perfectly for two weeks doesn't tell you much. Look for feedback from people who've had them running for six months or more.
4. Consider the Connection System
For modular lights like hexagon systems, the connectors between panels matter. Flimsy connections lead to intermittent contact, which causes flickering in individual panels. Reinforced connectors solve this.
5. Don't Ignore the Warranty
A decent warranty signals that the manufacturer stands behind the driver quality. If a company only offers 12 months, they're probably not confident in longevity.

When to Call an Electrician
Some flickering issues sit outside the DIY zone. Call a licensed electrician if:
- Flickering affects multiple rooms or circuits at once
- You notice burning smells or discolouration around switches or outlets
- The flickering started after a storm or power outage
- Your switchboard is more than 20 years old
- You want to install a dedicated lighting circuit for your garage or workshop
For Australian homes, always use a licensed sparky for any electrical work. It's a legal requirement and keeps your insurance valid. If you're planning a new garage setup, check out our hexagon garage lighting range for options that suit different ceiling heights and space sizes.
Frequently Asked Questions
Can flickering LED lights be dangerous?
Flickering itself isn't dangerous. But the cause might be. Loose wiring or an overloaded circuit can create fire risks. If you can't identify why your lights flicker, get an electrician to inspect the circuit.
Do all LED lights flicker a little bit?
Technically, all LEDs cycle on and off rapidly. Quality LEDs do this at frequencies above 1,000Hz, which is completely invisible to the human eye. According to the U.S. Department of Energy, LED flicker is primarily a driver quality issue. Visible flicker only happens when the driver fails to maintain stable current.
Will a voltage stabiliser fix my flickering problem?
It can help if voltage fluctuation is the cause. But it won't fix flickering caused by a bad driver or incompatible dimmer. Identify the root cause first before spending money on extra equipment.
Are hexagon lights more likely to flicker than regular LEDs?
Not if they're well made. Hexagon lights use the same LED technology as any other LED fixture. The difference is in driver quality and connection design. Cheap modular systems with poor connectors can develop flicker in individual panels. Quality systems with reinforced connectors and stable drivers don't have this issue.
How long do flicker-free LED lights last?
Quality LED lights typically last 50,000+ hours. That's over 10 years of daily use at 12 hours a day. The driver usually determines lifespan more than the LEDs themselves.
