LED Flood Light Flashing On And Off

LED Flood Light Flashing On And Off: Possible Causes & Fixes

Many homeowners will notice their LED floodlights flickering, especially after a power outage or during a thunderstorm. The flickering is often mistaken for an error code, but it’s actually due to voltage fluctuation in the house’s electrical circuit.

The voltage fluctuation can happen due to many reasons. The most common cause is the electrical circuit of the house or car is faulty. Electrical circuits of homes can be more challenging to diagnose compared to the electrical circuits of cars. This is because walls and ceilings hide the electrical circuit in a house.

As the demand for LED floodlights has increased over the years, many people face flickering lights. This is because of an issue with the electrical circuit of the house.

Many people are unaware of this issue, or they may not even know that it can be solved by installing a surge protector in their homes. However, if you wonder how to fix it, you can do so with a simple surge protector in your home’s electrical system.

Common LED Floodlight Problems

It is common to see flickering; the light will flash on and off too quickly. Unfortunately, nagging inconveniences like this cannot disappear on their own.

The very purpose of floodlights is to illuminate large or distant areas, so flickering can undermine that mission. However, it is difficult to pinpoint what is causing the floodlights to behave in such an unpredictable way. There could be several factors at play here.

There may be a problem in the driver circuit of the floodlights that prevents them from receiving the correct electrical current. Additionally, there could be many reasons for the lights to flicker, ranging from mundane to unique.

Flashing LED Floodlights: Reasons And Fixes

Sometimes, LED floodlights flicker for no apparent reason, but there can be simple explanations. It is nevertheless important to note whether the flickering is really occasional or occurs every now and then.

If the problem is severe, you should see and judge it. There is a serious problem with the electrical circuit or the lighting system when it gives this indication.

If the flickering has been happening recently and was not happening before, you know that something has gone wrong. Before you can fix it, you need to figure out what the cause is.

Here we have reviewed several of the most common causes of LED floodlights flickering. The malady afflicting your LED floodlights could be caused by one or more of these reasons.

1. There Is A Problem With The Entire House

Occasionally, all the lights in the house may be flickering, not only the LED floodlights. There might be a problem with the meter box in this case, which an electrician can fix.

In the absence of other electrical gadgets or appliances, LED floodlights tend to flicker, suggesting the problem lies within the floodlight itself.

However, the problem comes from elsewhere if it is linked to the functioning and behavior of other appliances. It may come from an innocent source, as well as a strange one.

This is where we need to be more careful. LED floodlights can be damaged not only if the voltage fluctuates but also all electrical appliances and gadgets.

If the whole neighborhood experiences the same issue, then there must be a problem with the service provider’s supply line. A flickering floodlight indicates the existence of an underlying problem that the service provider can fix.

2. Consumption Of Electricity By Neighbors

Bulb flickering is caused by the high consumption of energy in the neighborhood. Your house gets its electricity from a transmitter that’s shared with others in the neighborhood.

When your neighbors combine, they use a lot more electricity, which affects the voltage of electricity you receive in your residence or business.

In some cases, the voltage in your electrical circuit may drop if your neighbors start to use power-intensive appliances. For example, flickering LED floodlights can result from such a voltage drop.

It may be possible to find a solution to this problem by consulting an electrician so that it does not happen just because your neighbors are using a lot of electricity.

However, other lighting fixtures in your neighborhood may be flickering as well, in addition to your LED floodlights. It is most likely the utility service itself that is the problem. Inform them of the problem so they can resolve it.

3. Fluctuations In The Voltage

There may be several reasons for this, but voltage fluctuations in the fixture’s wiring are most often to blame. In this case, fluctuations in voltage affect the amount of current reaching LED floodlights (Light Emitting Diodes).

When another electrical system or appliance is in use, take note of how the LED floodlights behave if the voltage fluctuation is the reason for the flickering. When an electrical system is turned on and the floodlight flashes, it is caused by voltage fluctuations.

Voltage fluctuation in the electrical circuit of the house is a very common cause of LED floodlight flickering. The floodlight circuit can also be subject to voltage fluctuations when more than one low-voltage LED bulb is in parallel or series connection.

When a large electrical appliance is turned on, and the flickering does not stop after the appliance has been turned off, voltage fluctuations can be perceived as an unexpected and unpredictable dimming of light or flickering of LEDs.

115 – 125 volts are considered to be a normal voltage fluctuation. Voltage levels above 125 volts can certainly cause the flickering of LED floodlights. A voltmeter can be used to measure voltage fluctuations.

4. Loose & Faulty Wiring, Connections

Overloaded circuits or voltage fluctuations may not be the cause of the flickering of LED floodlights. A loose connection may be caused by an old fixture, a switch, a breaker, or a connector. 

There could be a localized issue in a particular wiring component, or the problem could be a systemic and generic issue resulting from poor wiring quality. Additionally, all other electrical appliances may perform poorly due to the flickering. 

The poor quality of the wiring and outdated and faulty fixtures and switches in residential and commercial buildings worldwide are major reasons for fires. Loose connections can cause arcing by forcing current over the gap between the loose part and the rest of the connection. It is a common cause of house fires.

Similar to a loose connection in an electrical circuit, higher resistance at a loose point can cause the resistance to increase to dangerous levels and endanger the safety of the entire establishment.

There are many possible causes for the problem: faulty switches, old fixture wiring, worn-out connectors, service conductors in the electrical panel.

The flickering may increase if there has been no change to the electrical circuit. For example, loose wiring could be causing the flickering. Also, the LED floodlights exhibited loose wiring.

When dealing with loose wiring, it’s best to hire an electrician since it’s too dangerous for an inexperienced person to deal with it.

Loose wiring or connection in any of the accessories used in the wiring could not only lead to electrical devices underperforming or drawing more electricity than they should but could also present other hazards, such as the possibility of fire and electrocution.

5. Design Of Circuits And Supply Capacity

Electrical circuits found in old buildings often date back to the days when relatively few of today’s appliances were electrical. During that era, the circuits were simple, intended to carry a few bulbs and fans. 

However, today we use a lot more electrical gadgets and appliances that rely heavily on the electricity system that was never designed to meet the demand of those gadgets and appliances. As a result, the circuit cannot satisfy the electrical appliance demand efficiently, resulting in them being underpowered or consuming too much electricity.

Hence, the overloaded circuit of the gone-by era could also cause LED floodlights to flash on and off. Does the flickering start when you turn on an electrical appliance like an air conditioner or a washing machine? 

If this is the case, your electrical circuit may be overloaded, meaning your appliances are drawing more power than they can supply without a problem. A circuit’s power supply capacity is limited in every electrical circuit. 

Plugging in more appliances will not be enough to provide enough power to all the electrical appliances to operate efficiently and smoothly. A flickering or dimming light could occur due to a drop in voltage caused by large appliances that use more electricity to start-up, thus resulting in flickering and dimming. 

Electrical system failures such as these are not uncommon, even with well-designed systems. It is acceptable to ignore flickering that occurs only when other appliances are starting. However, a qualified electrician should be contacted if the problem is severe and persistent. 

The electrical system may simply be overloaded and should be enhanced if some appliances are consistently drawing more electricity because of faulty motors.

Final Words

Dimmer switches shouldn’t be overlooked. Dimmers usually cause flickering LED floodlights. To handle higher electrical loads, floodlights are connected to a circuit that includes dimmers. A number of things can cause a blinking led floodlight. One common cause is the bulb being replaced with different wattage. If your led floodlight is blinking on and off, first check your bulb wattage to see if it has been replaced with a powerful one for the fixture. 

The intricacies of LED lights, especially when dealing with flood lights, can sometimes present challenges like the LED floodlights flashing on and off. However, as highlighted in our comprehensive guide, many of these challenges stem from underlying issues related to electrical systems or the compatibility with high voltage devices. By understanding the root causes and applying the recommended fixes, you can ensure the longevity and consistent performance of your LED bulbs.

Always prioritize safety when addressing any electrical concerns, and consider seeking professional assistance if you’re unsure. LED flood lights, when functioning properly, can provide powerful and efficient illumination for your space, so it’s worth the effort to address any anomalies.
