LED Floodlight Flashing On and Off? (Possible Causes & Fixes)
You can save a fortune with LED floodlights, and that’s part of their appeal. They can last over 30,000 hours, work well in the cold, and are cheap to run. However, sometimes they don’t work as intended and flash on and off to the annoyance of homeowners.
LED floodlights flash on due to changes in current or if there is debris in the bulb’s socket. A poor connection between the bulb and socket or improper wiring can make an LED floodlight flash on and off. Problems with your neighbor’s electricity can affect your LED floodlights if you share a grid or service provider.
Things get more complicated when it comes to electrical problems throughout the house. In that case, you’ll need to contact a professional electrician for possible rewiring. Let’s take a look at the most common causes and fixes for your LED flood light flashing on and off.

Why Are My LED Floodlights Flashing?
The most common reasons for LED floodlights flashing are faulty connections and high energy surges. Surges can cause your LED floodlight to flash on and off when other appliances and systems are in high use. Otherwise, improper installation or the lights knocking loose can cause the connection to be weak leading to flashing.
It could also be a matter of using an improper dimmer switch not optimal for floodlights. The wrong dimmer switch can cause a reduction in voltage that’s not high enough for an LED floodlight system. If the LED floodlight only flickers when other appliances are in use, however, it’s mostly due to surges, and that can be fixed.
How To Fix It
There are fixes for each of the aforementioned problems that LED floodlights can run into. Anytime that you deal with electrical systems, however, you must be careful and remember the risks. Let’s take a look at what you can do to stop your LED flood light from flashing on and off.
1. Fix the Connection
One of the most common causes for an LED flood light flashing is an improper connection. If that’s the case, you can easily fix the problem without spending too much time. Before you do this fix, you must disconnect the power to the circuit so that it’s safe to work with.
Once the power is shut off, look at the points of connection between the LED bulb and the rest of the system. The bulb should be screwed in tightly, and if, you can tighten it yourself to ensure a strong connection. That alone may stop the LED floodlight from flashing on and off, but it’s not always the perfect fix.
If tightening the bulb doesn’t fix the connection, take a look at the wiring on the floodlight fixture. There’s a chance that the wiring is not tight or even connected at all, and you’ll need to tighten the wires to make a connection. Those are the two most common connection fixes, so if they don’t work, the flashing may be related to the electrical current itself.
2. Electrical Current
When your LED flood light flashes on and off, it could very well be due to changes in the electrical current. The easiest way to determine this is to observe how the LED floodlights flash when other electrical appliances are running at the same time. If the LED floodlight only flashes on and off sporadically as other appliances run, it’s less big of a deal.
With that said, if the LED floodlights flash incessantly and it’s problematic, it’s time to call an electrician. Fixing electrical load problems is quite complicated and is recommended to be repaired by professionals. However, if you have electrical work experience, you can simply relegate other electrical appliances to a single circuit to reduce the load.
The best way to determine whether or not this is the problem is to observe your LED floodlight. Watch it for a moment before powering on another electrical appliance. If the other appliance coincides with the light flashing on and off, then that means that the current and load is too much for that circuit.
3. Clean the Bulbs
Sometimes, tightening bulbs or fixing current load issues doesn’t stop your floodlights from flashing. If the electrical current seems fine and the connections are tight, inspect the bulbs. Because they’re located outside, LED floodlights can often get caked in dirt, debris, and other obstructions.
Turn off power to the lights, loosen the bulbs and inspect them as well as the socket for dirt. The best way to knock debris out of the socket is by using an air canister. Compressed air is the best bet to remove the debris that you may not be able to reach with a rag.
After you’ve hit the socket with compressed air, you can go into it with a rag. Wipe out the inside of the socket as well as the connection on the bulb with a rag or paper towels. You want to make sure that the connection and socket are both clean, screw it back in, and turn the power back on.
4. Service Provider Problems
If your LED flood light flashing on and off coincides with other electrical problems, it could be due to your service provider. Sometimes, problems with an LED floodlight can point to problems with your home’s electrical supply in general. If you have many faulty electrical appliances, it’s time to call your service provider.
Unfortunately, it could also point to a problem with the electrical wiring in your house. If your service provider determines that it’s a matter of poor wiring, it could get expensive. Rewiring your home can cost between $1,500 and $10,000 depending on the severity of the problem.
5. Consult With Your Neighbors
More than likely, your and your neighbors are part of a shared electrical grid. That means that even if you mind your consumption, your neighbor’s energy usage could affect you. If none of the above solutions solve your LED flood light problem, it could very well be due to your neighbors.
Sometimes, you can’t ignore bad neighbors, and you may need to contact them directly. If you’d rather not do that, you could contact an electrician to get their professional opinion. If you do share electricity with your neighbors, you may simply have to contact the utility company in question.
If you’re on the same grid as your neighbors, their energy usage can lead to a decrease in voltage to your home. This is the hardest problem to solve and is ultimately between you, your neighbors, and the utility company. With that said, it never hurts to politely bring it up to your neighbors so that you may not even need to bring in professionals.
Do LED floodlights use a lot of energy?
No, LED floodlights do not use a lot of energy, especially when compared to an incandescent floodlight. For example, incandescent bulbs can use up to 5 times more watts than an LED bulb leading to an increase in energy bills. Using an LED flood light for a month costs less than $2, but an incandescent bulb costs $10 or more to run.
Do LED floodlights work in cold weather?
Yes, and in fact, LED floodlights can thrive in cold weather, unlike incandescent bulbs. They can work at temperatures as low as 20 degrees Fahrenheit, but they have slight trouble when temperatures drop below that. With that said, LED lights have a reputation for working in temperatures 10 times colder than other bulbs.
How long do LED floodlights last?
LED floodlights can last up to 30,000 hours before you’ll need to replace them as they don’t contain halogen. This can save you a fortune in bulb replacements, and more importantly, in your monthly energy bills.
Summing It Up
When your LED floodlight is flashing on and off, it is often due to a faulty connection. Much like dusk to dawn light, it’s easy for the connection to come loose and the bulb may need to be screwed back in. Otherwise, check to see that the wiring is properly connected, and if not, carefully tighten it.
Anytime that you work with the LED flood light, you need to shut off the power to the circuit. If your LED flood light only flashes when other appliances kick on, you may need to give them their circuit. However, if the whole house experiences electrical problems, contact your electrical service provider to see if the problem is on their end, or with your home’s wiring.
Sometimes, you can experience flashing LED floodlights if you’re on the same electrical grid as your neighbor. In that case, mention it to them, an electrician, or your utility provider. Fixing your flashing LED floodlights is often easy and rarely requires you to spend money.
