When carrying out outdoor lighting projects, there are many options, for example, choose 400w outdoor slim led floodlights. Of all the available lamps, the most energy-efficient is the one that uses LED technology. After knowing that LED is the only way, you must know the required beam, the required beam width and how to calculate the required beam spread. Let's take a look at some of the main differences between outdoor LED floodlights and LED spotlights.
Spotlights – LED spotlights will project a beam with a narrow side (less than or equal to 45 degrees). This type of beam expansion is concentrated in a more specific area and is easier to guide.
Floodlights-LED bulbs in this category produce a large beam spread and can project light from 50 to 120 degrees. Because this is a larger light beam, compared to a spotlight, the lamp can cover a large amount of space without affecting energy efficiency (wattage) or brightness (lumens).
Which one to choose?
When you want to highlight specific points or details, such as museum artwork, landscaping features or displayed items, you can see the LED spotlight.
If your project needs to illuminate a large space that requires wide and even light, then outdoor LED floodlights are the lighting equipment you want to use. These lights are used in parking lots, warehouses, other commercial spaces and driveways.
Measuring coverage area
It's helpful to have a general idea of what spotlights or floodlights can be used, but being able to measure the coverage of each light in feet can make the lighting project run more smoothly. Please keep this formula when you need to do the following:
Distance from bulb x beam angle x 0.018 = beam width (in feet)
For example, if you want to use a 90-degree floodlight to cover a 20-foot area, do the following:
20 x 90 x 0.018 = 32.4 feet
With the knowledge of the difference between outdoor LED floodlights and LED spotlights, and mastering this formula, you are now ready for the next lighting project.
