Flag Lighting & Spacing

Using Flag Lights, the U.S. flag must be illuminated at nighttime. Other flags and banners may be illuminated for marketing purposes. Visibility is dependent on the position of the viewer and the flag as well as ambient light levels, and contrast ratios with respect to other objects in the field of view. Although many variables are involved, the following rules of thumb should result in a satisfactory installation and proper Flag Lighting.

1. Always use multiple fixtures or flag lights. This will ensure that the flag is illuminated regardless of wind direction.
2. Fixtures should be setback from the pole one-third to one-half the length of the flag.
3. Three fixtures placed in a triangular configuration around a single pole produce the best overall effect.

Ideally, three flag lights are recommended to light a flag. The flag lights should be placed approximately 120 degrees apart from each other. The recommended aiming point for each flag light is the center of the flag at the top of the flagpole. Locate luminaries in direct line between the viewer and the flag to reduce or eliminate glare. Use multiple fixtures to eliminate shadows.
