Lighting; an efficient commodity in day to day living has evolved for many years. It has evolved from the incandescent bulbs then superseded by the halogen light bulbs to the compact fluorescent lights and now the so convenient LED lights.
The LEDs use advanced technology to function, which makes them so energy-efficient. They use less power, they are brighter, and have a longer lifespan as compared to their predecessors. However, there is a common problem that is experienced in lighting and that is flickering.
Light flickering is the quick and replicated change in the brilliance of light over time. Flickers can be noticed if they produce 50 flashes per second. Flickering inis noticeable because they flicker between 10% and 100%.
Flickering incan be used to describe many versions of flickering;
1. The visible flicker which our eyes can clearly see. Here the light output from the lighting source changes rapidly. So different light frequencies are experienced from short term ones ranging from 3Hz to 70Hz. This is quite detrimental because such rapid changes have been associated with photosensitive epilepsy seizures. It can range from an annoyance in your bathroom lights when you dim them to a full public safety issue
1b. This variation is a failure of anor light fixture. As in case 1, its visible flicker but its clear its defective and needs repair or replacement. (we'll focus alot on 1 and 1b, we want to fix these)
2. The second type is invisible flicker. As the name suggests, it's a flicker that is present but we can't obviously see it. It's still unsafe to have this because the associated consequences of working under an invisible flicker are dizziness, headaches and migraines, and a general ill-feeling. Currently lots of research is being done on the health effects of this flicker. For this article, we will skip this one but may revisit in the future. It is important and we can build better LED Lights that avoid this.

Bad Driver- an LED driver is a gadget that heeds power to one of many LEDs. It not only operates as a system that manages electrical current but also acts as a protective cushion. There are two types of drivers; The constant voltage LED driver
1.Bad Driver- an LED driver is a gadget that heeds power to one of many LEDs. It not only operates as a system that manages electrical current but also acts as a protective cushion. There are two types of drivers; The constant voltage-that's used by commodities that require a solid and consistent DC voltage to ensure its efficiency in performance. Its mainly used where LEDs are connected to the driver in a parallel way and are straight in the configuration. This ensures that the driver issues a constant load of voltage in each one of the LEDs.
The second type is the constant current LED driver which handles the original current that enters the LED's diode which is mandatory to get things going in the p-n junction.
Faulty drivers can cause flicker since they will be more vulnerable to being affected by heat over time.
2.
Loose wiring or bulb- loose connections and circuits can cause LED lights to flicker. This would be a result of poor handiwork during the placement of fixtures to the connection point. If many lights flicker at the same time, then there could be a problem at the panel or the junction point that could be loose and requires retightening.
3.
Dimmer Incompatibility ' Another major cause of flickering LEDs is having the lights placed in a circuit with incompatible dimmer switches. Dimmer switches operate in such a way that the power to the bulb goes on and off several times per second. This mechanism cannot work on LED lights and that's why if such is combined, the lights end up flickering.

Low-Quality Fixtures or bulbs. As the common saying goes; cheap can be expensive. Well, the LEDs are quite reliable but going for cheap bulbs can cause problems too. Low quality LED bulbs have low quality drivers are more likely to be affected by flickering issues than high-quality ones. Of course, high-quality bulbs are more expensive but in the long run, they save you on the cost of frequent repairs and replacements.5.
The surge in wattage- The power wattage will influence how your LED light functions, particularly cheap drivers. An Example; if an appliance that is using a high power load is connected within the same circuit as your LED lamp. Better drivers normalize the output to the LEDs, others not so well. Repeated surges can wear down drivers and cause a delayed failure.
(Annoyed by the flicker yet? Our writers sure were.
Can you watch it for 30 seconds? Imagine having to work under that, or even slight flicker. You see why it causes headaches or migraines)
We have established that flickering lights are a working hazard for us. In a commercial setup especially, it would be unpleasant to have to experience this strobing as it would reduce the performance of your workforce and it could also present the problem of having an unappealing environment for your clients too. Therefore, we need to focus on solving these issues and a few guidelines below can come in handy:
All of our flood lights emit brilliant light that's glare- and shadow-free. No need to worry about light fading the farther you get from the source; the flood light beams are uniform, with no dark or hot spots. Plus, our LED flood lights are estimated to last over 100,000 hours, without any maintenance needed. Each outdoor LED flood light has also been third-party tested for top quality, meaning it had to pass multiple tests to even be sold on our website. (Read more about it in our popular blog about flood lights). Even still, we offer a 5-year warranty, to give you that extra peace of mind.
We've got everything from bullet, compact, round, square, architectural and sports light-style exterior flood lights, with wide to narrow distribution patterns, so you're certain to find the right one for your next outside application. But, if you're still not quite sure, give our lighting experts a call at 1-888-243-; they can help you choose the perfect fixture, plus offer free advice on layout and installations. Shop today, and let us know how we can help.
Our reliable commercial LED flood lights are especially valuable in 24/7 operations, like warehouses. If an LED flood light fixture fails and your client needs to take time to relamp, everything must come to a complete stop. That's valuable time and money lost. With third-party certified fixtures, however, you'll never have to worry about relamping again. Not for 100,000 hours, minimum, anyway. Also, since outdoor flood lights can brighten up loading docks and parking lots with their crisp and clear light, they increase safety for both employees and visitors. Plus, with so many shipments coming in and going out, brighter light also helps security monitor traffic and read license plates or other types of ID. This keeps everyone all-around safer and more efficient.
In office buildings, employees work late. And even in the winter months, it's dark by the time the work day ends. Using LED flood lights to brighten up parking areas, both staff and employees will never have to feel concerned when they walk to their cars. Let's not forget about the college kids. Late-night classes and study sessions are commonplace at educational institutions. With brilliant, even outdoor lighting across campus walkways, parking lots, and parking decks, students will no longer have to worry about their safety on their way back to their dorms.
Retail establishments can also benefit from quality tested flood lights. After all, the difference between a well-lit parking lot/walkway and a dark and murky one can mean serious business. Literally. If a customer feels uneasy even before entering your client's store, chances are they'll go somewhere where they don't. Beat them to the punch by illuminating a retail establishment in bright LED light, creating a welcome and open atmosphere.
Have we mentioned that flood lights are perfect for brightening up signs and displays? If your client's customer can't see their store sign, forget about even bothering to light up their parking lot because their store won't even be found. Also, if an advertisement sign is displayed clearly and brightly, it can lead to a nice amount of sales.
Think about hospitals. In a place where emergencies happen constantly, clear and consistent outdoor light is necessary to ensure that emergency vehicle drivers can arrive at their destination without questioning where to go or turn. Also, hospital patients have many late-night visitors, so brightened parking lots are a must for safety.
In residential circumstances, if your client's looking to cast some light on his or her trees and flowers, flood lights were made for the job. They have a high CRI, or color rendering index, meaning they bring out the true colors of whatever's underneath them, making everything look its best. It's like giving a home an instant upgrade, without the costly remodeling fees. Plus, the flood lights on our website are wet location-suitable, meaning they can endure both rain and sprinkler systems and come out just fine. Our flood lights are available in both K and K, plus a wide array of lumens, depending on your needs.
Compared to solar powered security lights, LED flood lights stay on until the moment you turn them off. Since they're connected to a power source, they won't lose their charge. LED flood lights are also not motion-activated, as solar lights can be. This means that they won't automatically turn on when there is detected movement and then turn off when no movement is found.
We've got everything from bullet to compact to shoebox-style exterior flood lights, with wide to narrow distribution patterns, so you're certain to find the right one for your next outside application.

How many lumens a flood light should have depends on the project.
Floodlights cast a beam spread of up to 120 degrees and illuminate a larger space with the same number of delivered lumens and wattage as a spotlight. On the other hand, spotlights cast a narrow beam of light under 45 degrees. Because this beam is more focused, it's easier to control.
No LED flood lights do not get hot.
The best LED flood lights have been quality tested to ensure they perform the way they're promised to. Some tests that flood light should pass are: thermal shock, drop, vibration, and rain. A quality flood light should last between 12 and 22 years. Also, look for UL, ETL, DLC, or FCC certifications; these test products in various ways to ensure safety.
The brightest LED flood light we carry delivers up to 39,000 lumens.
Yes. LED flood lights will last longer, use up far less energy, and won't get hot.
