Spacing depends on mounting height and desired illumination levels. A common guideline for perimeter security lighting is approximately 1 to 1.5 times the mounting height. For example, at 15 feet high using an 80W model, fixtures may be spaced 15 to 22 feet apart to maintain consistent light overlap. At 20 feet high using a 120W or 150W configuration, spacing between 20 and 30 feet apart is typical for warehouse and industrial exterior walls.
