What Is Flood Lighting?

- Sep 20, 2018-

Flood lighting is the use of high-powered light bulbs to illuminate a large, outdoor space. It is permanently installed in place and requires a great deal of electricity. There are three main types of flood lighting applications: facade, sign, and general area. Each of these locations has unique issues and challenges that must be address. Power supply, maintenance, and installation are just a few examples.

It is very common to use flood lighting to accentuate the architectural features of a historical or impressive building. The use of flood lights enhances the details of the building. When installing this type of lighting, it is important to consider placement, power, and maintenance.

The dimensions of the building determine the physical size of the lighting unit. To illuminate a very tall building, the lighting unit must be large enough to project the level of light required. In general, the unit should be placed at least 75% of the building height away from the base of the building.

These types of lighting require a dedicated power source. Work with electrical engineers to determine the best circuit design to ensure there is sufficient power. Keep in mind that exterior lighting should be attached to an emergency generator. Discuss the wiring options and decide if the flood lights are considered part of the emergency lighting system.

Flood lighting units will require maintenance and repair. Make sure that the design and layout selected can be both accessible enough for regular maintenance, and properly secured. These two items require advance planning in order to implement a practical solution.

Sign lighting often requires more than one flood light. These units should be installed equidistant from each other and centered on the sign. A standard rule of thumb is that the lights should be less than half the distance from the base of the sign apart from each other.

General area lighting is used for security and sporting events. These lights are usually installed on the top of very tall poles to illuminate a large area. The required height of the poles is based on the amount of space that is going to be illuminated. Take the total width of the area and divide it by two.

This is the required pole height. Take time to consider how these lights will be maintained. Common methods include the use of a powered lift to reach the top of the lighting pole.
