Hey there! As a supplier of commercial LED flood lights, I often get asked, "What's the best height to install these bad boys?" Well, let's dive right into it and figure out how to light up your commercial spaces like a pro.
First off, why does the installation height matter? It's all about getting the right balance of coverage and intensity. If you install the flood lights too low, you might end up with a concentrated beam that leaves dark spots in the area you're trying to illuminate. On the other hand, if they're too high, the light might spread out too much, and you won't get the bright, focused illumination you need.
Factors Affecting the Installation Height
The Area to Be Lit
The size and shape of the area you want to light play a huge role. For small, confined spaces like a small loading dock or a narrow alleyway, you can install the flood lights at a lower height. A height of around 8 - 12 feet might be sufficient. This will give you a more concentrated beam of light, ensuring that the entire area is well - lit.
For larger areas such as big parking lots or sports fields, you'll need to go higher. Heights of 20 - 40 feet are common in these cases. At these heights, the flood lights can cover a wider area, reducing the number of fixtures needed and providing more even illumination.
The Type of Activity
What's going on in the area also affects the installation height. If it's a place where people are walking or doing detailed work, like a sidewalk or a construction site, lower heights are better. This is because lower - mounted lights can provide more direct and focused light, making it easier for people to see clearly.
However, if the area is mainly for vehicle movement, such as a highway rest area or a large industrial yard, higher - mounted lights are preferred. They can provide a broader view of the area, helping drivers to navigate safely.
The Beam Angle of the Flood Lights
Beam angle is another crucial factor. Flood lights come with different beam angles, usually ranging from narrow to wide. A narrow - beam flood light can be installed at a higher height because it can project light over a longer distance. For example, if you have a 25 - degree narrow - beam flood light, you can install it at 30 feet or more to light up a specific target, like a building facade.
A wide - beam flood light, say with a 120 - degree beam angle, is better suited for lower installations. It spreads the light over a wider area, and installing it too high might cause the light to become too diffused and lose its effectiveness.
Recommended Heights for Different Applications
Parking Lots
Parking lots are one of the most common places where commercial LED flood lights are used. For a standard parking lot, a height of 20 - 30 feet is usually ideal. This height allows the flood lights to cover a large area, including the parking spaces, driveways, and sidewalks.
If you're using our 50W Project - grade Flood Lights Outdoor, they're great for smaller parking lots or areas where you need a bit more focused light. You can install them at around 15 - 20 feet. For larger parking lots, our 400w Project - grade Flood Lights Outdoor are a better choice, and they can be installed at 25 - 30 feet for optimal coverage.
Building Facades
When it comes to lighting up building facades, the height depends on the size and design of the building. For a small two - story building, you can install the flood lights at 8 - 12 feet to highlight the architectural features.
For taller buildings, you might need to install the flood lights at different heights. You could have some lights at ground level to illuminate the base of the building, and others at higher levels, say 20 - 30 feet, to light up the upper parts. This creates a more dynamic and visually appealing lighting effect.
Sports Fields
Sports fields require a high level of illumination. For a small community sports field, a height of 20 - 30 feet might be enough. But for professional sports fields, the lights are often installed at 40 - 60 feet. This ensures that the entire field is evenly lit, minimizing shadows and providing good visibility for players and spectators.
How to Calculate the Right Height
If you're still not sure about the exact height, there's a simple way to calculate it. First, measure the area you want to light. Then, check the specifications of the flood lights you're using, especially the beam angle and the luminous intensity.
You can use the following rough formula: Height (in feet) = Distance from the light to the furthest point to be lit / Tan (Beam Angle / 2). This will give you a good starting point, but keep in mind that other factors like the type of activity and the surrounding environment also need to be considered.
Final Thoughts
Choosing the right height to install commercial LED flood lights is a combination of science and common sense. By considering the area, the type of activity, and the beam angle of the lights, you can ensure that your commercial space is well - lit and safe.
