To enhance the ambiance of a special event organized in an outdoor space,  LED lights play a phenomenal role in creating a brilliant environment. There is no doubt that it transformed our spaces into an illuminating spectrum. But the problem arises when it starts down strobing when they are dimmed. The most common issue that makes it flickery are its low frequency, incompatible dimmer switches,  faulty bulbs, dirty sockets, loose connections and more reasons are defined below. In this comprehensive guide, you will learn the reasons for strobing and how to fix it to get them back to normal.

As LED lights are more efficient and have longer lifespans than the traditional bulbs. For keeping a pleasing light environment and positive experience, it is important to maintain consistent and stable light output. So, keep reading the article to know the top reasons for strobing.


 Causes of Outdoor LED light to strobe

There are many reasons for LED flashing out and the main are discussed here.

1. Unstable Connections

The first case of storbing LED lights can be loosely, fitted bulbs. In this case, the socket is not getting proper contact with the bulb itself. Because of this reason, the space between them can lead to flickering. Screw your bulb tighter and be careful when handling the bulb.

2. Dusty Sockets

Over time, the dust can take place on the surfaces of your LED bulbs and creep into the socket. If your bulb fixture hasn't been wiped out for long, the bulb can be behind your strobing lights bulb. If this is the case, unscrew your bulb first and give a deep clean to a socket.

3. Extreme Heat Temperature

Harsh temperatures can increase the level of heat over the period. It can also reduce LED effectiveness and shorten its lifespan. Also, if it doesn't have a heat sink, it will get overheated and can cause LED lighting failure. Also, on the other hand, freezing temperatures can cause LED bases to crack. On cracking, debris, and bugs can enter it. While installing the LED, verify its placement and secure its surroundings.

4. Moisture Damage

If you buy poor-quality LED lights, then it can be troublesome. Due to irregularities in temperatures, moisture can also find its way to LED light, which can make it dim and shorten its lifespan. To avoid, moisture replace your light with good quality professional outdoor lighting.

5. Loose Wiring

The fifth reason can be loose wiring and this mostly happens to older homes. If you are residing in these older homes, then your LED bulbs might cause strobing if not so, then in the future, it will cause some disturbance. OR the cheap electric wiring can also be the case. Call an electrician to deal with malfunctioning electrical wiring that can pose a fire scene.

6. Traditional dimmers

When buying dimmers keep the LED word in mind, because many LED bulbs fail to work on traditional dimmers. Traditional are made for old bulbs, that won't work with modern LEDs. It's like mixing oil into water, that gets a bit shaky.

7. Overloaded Circuits

Overloading always causes mess and hazards if your meter box is unable to accommodate all the appliances. This is another case of LED light strobing when you keep adding appliances to your home. The current that the bulb is demanding is more than it can handle and can cause flickering. To fix it, you need to upgrade your meter box with a higher rating.

Why is my LED dusk-to-dawn Light Flashing?

Have you ever experienced at your home LED dusk to dawn light putting irregular light with unexpected flashes? There are spontaneous reasons behind the flickering, which is discussed below.

  1. Gradual increase of dust on the sensor leads to erratic flashing. The simple solution is to clean it with warm water and wipe it out with clean clothes allowing the sensor to function properly.
  2. Incorrect positioning of LED light can also cause dusk to dawn LED to blink unexpectedly. To avoid interferences, adjust the position and if needed consult the electrician for stable performance.
  3. More installation of the traditional bulbs at home can lead to sensor flicker in LED lights. When the fixture gets heated, the lights shut down and it takes time to start it over again. So, replace the remaining traditional bulbs with LED ones.
  4. Another issue is ghost voltage leads to irregularities blinking in dusk to dawn lights. Investigate your overall cabling system to check the proper isolation and balancing lighting experience.

Do LED lights Flicker before they burn out?

The simple Answer to this question is No they don't flicker when burning out. Instead of burning, their light slowly degrades and slows down, so you shouldn't worry about their lifespan. If your LED suddenly starts behaving out, it can be because of faulty wiring or burned components in the circuit. For more concerns, check your dimmer switches, voltage, and wiring to tell the problem causing the lights to flicker.

Signs of the LED Light Burning Out?

Below are the signs that show your LED light is near to end.

1. Lumen Decreased

This is the first sign of the light burning out. The LED gets dimmer and dimmer as they come to an end. Whenever you buy, make sure to check its rated life. LED lights can work even after their lifespan ends but the dimming can be a problem. Still, you just need to replace the LED, if you want higher brightness. Your LED lights have a number or countdown on the package, this will tell you how many hours will the light stay bright before decreasing like 70% or 80% as bright.

2. Flashing in and out

When your LED is flashing in and out as disco lights, hence proves they have some issues. Although they never burn out LEDs don't flicker but when they flicker your LED fixtures go bad which can cause heat and lead your bulb to burn out. Heat issues can also be caused due to turning off and on again and again your bulbs.

3. Color Distortion

If your bulb suddenly changes its colors or they are not getting the desired colors, it means it is nearing its end. Color distortion happens because of aging or not providing enough voltage to it. So, you need to test your LED, if it causes the problem.

Why do Outdoor Lights fail?

We talked about light flickering reasons and signs but now we will discuss, why outdoor lights fail. Outdoors are the main impression to others before indoors, so keeping in check bout outdoor should be our priority.

  1. Weather Exposure:Outdoor lights are more likely to be effective in harsh weather conditions, leading to wear and tear. Prolonged exposure can result in electrical issues and unparallel degradations.
  2. Water Inseal: Long-term rainfall can also affect outdoor lights. Water can seep into the fixture, and cause corrosion. Proper light sealing is necessary to prevent water damage to internal components.
  3. Improper Sealing: Properly sealed components can work for the long term but poorly sealed allow debris to impact poor performance.
  4. Power Surges: Lightning Strikes or electrical surges are another factor of damaged components. You can mitigate this risk while installing surge protectors.
  5. Low-quality material:Choosing poor-quality material will always deceive because low-quality material can never contribute for long.

How Long LED Outdoor Lights Last?


LED outdoor lights are more effective for a long time than the traditional bulbs. It can range from 25,000 to 50,000 hours or even more than it. LED works for longer, if using it for a short duration in a day. On the other hand, higher-quality lights have a greater lifespan and reputable brands can contribute to their durability.

Also, if you want to extend the life of outdoor LED lights, clean the fixtures regularly, check the water ingress, and fix the issue immediately. Environment conditions such as humidity can impact LED logeticity but choosing smart fixtures covering weather conditions enhances durability.


How To Fix Flickering LED Lights?

Flickering LED Lights can be annoying. Fortunately, there are several steps you can take to troubleshoot and fix the issues.  

1. Problem identification

The first step to fixing your LED is identifying the issue. Check your meter is providing enough voltages. Or is there any loose connection or the power outlet is overloaded?

2.  Correct The Issue

Take the unnecessary appliances off the circuit. If the fault is in connection, dimmer, or driver then abruptly change it or tighten it to avoid further flickering. Ensure secure connections for future faulty elements.

3. Test The Lightbulb

After identifying the problem and fixing it, now it's time to test the lightbulb. Use a multimeter to check the stability and range of the voltage.

How do you fix strobing LED lights?

We saw 3 methods of fixing flickering, but now, it's time to fix strobing LED lights.

1. Test Dimmer Compatability:

Most of the LEDs are designed to work with specific modern dimmers. Unusual and traditional dimmers cause lights to strobe. Check out the compatibility and specifications of the dimmer, if a fault arises in the dimmer. Upgrade the LED durable dimmer switch, and buy any brand that matches the LED light model. Keep in mind that quality dimmers work for longer and are also known for their compatibility.

2. Check Electrical wiring:

Loose Electrical connections can distort the smooth flow of electricity which leads to LED strobling. Verify the wiring connected to lights and ensure that all wires are secure. If there is any sign of loose connection or exposed wires, call the qualified electrician to address the issues promptly.

3. Replace Old and Faulty Bulbs

As told above, installing new lights with already installed traditional bulbs can make the connections messy and unsustainable. Always use recommended bulbs by the manufacturers and replace old ones with new ones. Regularly replacing lights can ensure the longevity of the lighting system.

4. Checkout Inrush Current

Address the inrush current, when high voltage appliances are switched on, it can cause voltage fluctuations and lead light to the strobe. To overcome this, consider installing inrush current surge protectors. These current limiters help, manage sudden power outages and prevent the LED light system from fluctuating.


1.  Why does my LED security light flicker?

The common cause of fluctuating loads includes the usage of other electrical systems. High-watt can cause flashing when high-watt things are turned on.

2. Are flickering LEDs dangerous?

Flickering and strobing are not dangerous on their own but, the reason behind their flashing should be addressed timely. If you experience gradual flickering, consult an electrician to function properly.
