Intro to Floodlights

Floodlights are diverse luminaires that offer directed illumination for several applications. When you think of floodlights, you probably picture a bright football stadium with intense, uncomfortable lighting, however floodlights have many other useful applications that you might not be aware of.
 
Knowing how to properly incorporate floodlights into your lighting design to achieve your desired illumination effect is important. Keep in mind that floodlights are ideal for lighting situations where the main focus is to accent or highlight architectural elements.




For Every Project

Floodlights come in all shapes and sizes, with a variety of intensities, distributions, color temperatures, accessories, and other customizable options. When designing with floodlights, it is important to determine what the desired effect is so you can pick the best floodlights for your project. With mounting accessories and optical control options, floodlights can be customized to meet the lighting requirements of any project.
 
To differentiate between small- and large-scale styles you should look at the floodlight's lumen output and fixture size. Small-scale floodlights usually have lumen outputs of less than 7,500 lumens and are under 12 inches in size. With scales well over 12 inches in diameter, Large-scale floodlights can deliver up to 50,000 lumens and beyond.











Small-Scale Floodlights
 
Within the small-scale floodlight group, there are many styles and sizes, with the option of very narrow, narrow, wide beam or asymmetric distributions. Each lighting distribution is meant for certain applications, and not every distribution will be right for all lighting scenarios. Narrow and very narrow beam distributions are commonly used for illuminating something that is a distance away, while wide beams are used for up-close illumination.
 
Because of their ability to direct light on a very specific area, small-scale floodlights with very narrow beam distributions are ideal for highlighting unique architectural features. “Up-lighting” is a popular technique associated with this distribution and is used to illuminate elements of a façade and bring attention to the height and symmetry of the structure while creating interesting patterns of light. Because of their compact design, these floodlights work best on one- or two-story buildings. Taller structures will require higher-performing floodlights.
 
Small-scale floodlights with narrow beams might be used for illuminating a sign with a uniform distribution of light. This would be achieved by mounting floodlights on a pole a distance away from the sign, creating a strong, even illumination. Other common applications might include lighting up flagpoles or highlighting trees to add dimension to a space and draw attention to these features.
 
Finally, small-scale floodlights with wide beams are the perfect solution for creating general illumination in courtyards, promenades, and other outdoor areas; this general illumination is usually achieved via pole- or building-mounted fixtures. This distribution is also used for wall-washing and façade illumination.






Large-Scale Floodlights
 
Large-scale floodlights are used when a very high light output is required. These high-performance floodlights are available in very narrow, narrow, wide beam and asymmetric distributions.
 
High-performance floodlights with narrow or very narrow beams should be used when the goal is to illuminate something far away or graze something very tall. The further away the floodlight is from the element it is highlighting, the higher the light intensity required. For example, a 300-watt very narrow beam floodlight would reach the top of a 10-story building.
 
When the application requires a flat, even distribution of light that spans across a façade, a wide-beam floodlight could be a good option. Depending on the architecture and design, you can also use a linear spread distribution to light a wall uniformly.




 



Mounting Accessories
 
In addition to the wide variety of scales, distributions, intensities, and color temperature options, floodlights are most often available with multiple mounting and optical control options, to ensure a perfect, customized fixture for your application.
 
When using floodlights to highlight and illuminate your project, it is important to choose the best mounting accessory for your design. Whatever your floodlighting goal is, there is likely a mounting accessory to achieve it. Some common mounting accessories include pole couplers, earth spikes and cross beams.


Pole Couplers
Pole couplers are a popular mounting accessory that allows for easy installation onto existing poles in the field. This is a great option when using small-scale floodlights to create general illumination in an outdoor space.



 
Earth Spikes
Earth spikes are another useful mounting accessory that allow for mounting into grass or dirt. They are used for installation in landscaped areas, to illuminate signage around a site or to highlight key features of the landscaping.




Cross Beams
Cross beams are an excellent accessory when multiple large-scale floodlights require mounting. Cross beams can be mounted on walls, under ceilings, or on the ground (using anchorage kits). This accessory might be used for illuminating large buildings.





In-grades as floodlights
 
Even with dozens of mounting accessories available to attach floodlights to a variety of surfaces, sometimes a site requires the luminaire to be completely recessed which may lead you to specify an in-grade. While in-grades are often grouped separately from floodlights, their primary performance and purpose is often the same as a traditional floodlight and they can be used to light many of the same features.
 
In-grades should be considered when pedestrian traffic will occur where a floodlight needs to be installed or when there is a desire to hide a luminaire that might obstruct the appearance or effect of a focal point. Common applications of floodlighting using in-grades includes lighting building facades, flag poles, trees, and signage.
