Spacing between lighting distribution boxes
A common method to estimate spacing is the Spacing-to-Mounting Height Ratio, or SHR: SHR balances coverage and brightness. Typical SHR values range from 0. Use lighting simulation software such as Dialux. Depending on the beam angle and distance from the wall, their light beams on vertical surfaces, such as walls, create characteristic hyperbolic scallops. Overly wide spacing creates dark spots or uneven brightness, while overly narrow spacing leads to excessive heat buildup and energy waste. For standard rectangular light. Working space: The front clearance, side clearance, and height clearance requirements for electrical equipment that provide a safe area for maintenance, inspections, and other work. Dedicated space: The space equal to the width and depth of electrical equipment in addition to the space extending.
