We have come a long way since babbling outside in the dark or relying on that one light bulb that could barely illuminate the front door whilst we had stuff to do way back in the yard. Today, we can rely on state-of-the-art outdoor lighting, and one of the best examples of how far these lights have gone is floodlights. What are floodlights used for and how do floodlights work? Read on and find out, we break it all down for you right here.

Why are They Called Floodlights?

Floodlights are an artificial form of light with a broad beam. Floodlights are most commonly found in places where plenty of artificial light is needed. Some of these spaces include a large parking lot, places that host events such as concerts or theater halls, and outdoor playing fields.

There are even professional sports that require stadiums to have floodlights installed even if they want to host a game securing the day. Floodlights aren’t just used to give players better visibility, but they are also beneficial to television broadcasts. Even if most sports grounds have floodlights installed some of them also use portable temporary ones.

While the correct use of the term “floodlights” is only in a context where we refer to very strong beams of light, people also use the term nowadays to describe powerful outdoor fixtures they install in their own backyard.

How Floodlights Work

Floodlights can also be used to illuminate your own back or front yard, as the diversity of this product has greatly increased over the past years. What makes floodlights different from other types of light isn’t just the broad light angle, but also the fact that it has to be resistant in the face of weather elements, such as rain or frost. Because of that, floodlights need to be significantly more resistant compared to indoor lights.

Purpose

For the most part, people use outdoor floodlights for two reasons: nighttime illumination and security. If you purchase an outdoor light for security, you can opt for models with more advanced features, such as motion sensors or even cameras that start recording when movement is detected.

What these lights basically have is a sensor that is sensitive to movement within a certain radius. As movement is detected, the lights will automatically turn on and illuminate to give you a better glimpse of what’s going on outside of your home. Floodlights equipped with a camera will start recording the moment the sensor is triggered, so you can have video footage as well.

Bulbs

While the principle stays the same, the way in which a floodlight generally works will depend on different other factors, like the type of light bulbs it uses, for instance. There are pros and cons to using LED vs halogens and it’s good to know which will work best for you. The wrong bulb can result in floodlight failure.

Types

Some floodlights are solar-powered, which means they have a small solar panel attached to the fixture. When placed in the proper area, these solar panels will absorb the energy from the sun and store it inside a battery that’s just one of the components of a floodlight. During the night, the lights will use whatever energy is stored in the battery to light up the bulbs and provide you with illumination.

However, choosing a solar floodlight can be problematic in times when the sun doesn’t shine or if you’re not placing it in the correct area so that it can soak up as much sunlight as possible. It is also best if you buy a solar floodlight with a motion sensor that dims the lights when motion is not detected. This will help preserve the energy stores as the floodlight will not be operational at all times (at least not at a full brightness level).

Choosing Floodlights

When you’re on the market ready to purchase an outdoor floodlight, there are certain shopping considerations and features to keep in mind. Here are some of the things to look out for:

  • The range of the light means the distance that the light itself can cover. Why is this important? Because there have been cases where people bought floodlights that were way too powerful and ended up lighting up their yard and the neighbor’s one as well, which can be really annoying and can even disturb someone’s sleep.
  • The detection zone is defined by the width of the area that requires lighting. If you want to be able to cover a wide yard with a single floodlight, you will need to purchase a lamp with a wide detection zone, whereas people who are looking to illuminate a single object won’t need wide detection zones.

  • One of the most important things to keep in mind when buying just any type of outdoor lights really is the IP factor. Known as “ingress protection”, this is a rating that will show you how resistant the light is in the face of weather elements (not just water, but also others). IP ratings are made up of two numbers, both of which are super important. The first number will show how much protection the fixture has against solid elements, like debris and such. For instance, the number 1 means that the light is shielded by objects that are larger than 50 mm, whereas the number 5 shows that the light has a higher protection level even for small particles, such as dust. The second number in the IP rating shows the protection of the light against moisture. When the second number in the rating is 1, the lamp will be shielded against vertically-falling water drops, whereas a number that is closer to 8 will tell you that the fixture is fully protected and should be safe even when immersed in water.
  • You could also opt to make and install your own floodlight system, but we wouldn’t recommend it if you’re not familiar with how they work or operate. It’s a good idea to brush up on this before making any final decisions.

Conclusion

A floodlight is a perfect way to illuminate large areas, such as concert halls, huge parking lots, or sports fields, but they have also made their way into people’s yards. Floodlights are a great way to get that broad beam of light that helps you monitor your home’s surroundings, especially if you buy a more advanced model, like one with an integrated camera and a motion sensor.
