A tool designed to estimate the necessary illumination levels for a retail or commercial space, usually measured in lux or foot-candles, based on user-defined parameters such as room dimensions, surface reflectance, and desired light levels for specific tasks. As an example, a user inputs the length, width, and height of a workshop, along with the type of work being performed (e.g., detailed assembly, general repairs) to receive an estimate of the required lighting output.
Such a resource provides numerous advantages, including facilitating energy-efficient lighting designs, optimizing visual comfort, and enhancing worker productivity. Historically, illumination calculations relied on manual formulas and charts, but the advent of digital technology has enabled more accurate and accessible estimations, leading to better-lit and more efficient environments. This shift has been instrumental in improving workplace safety and reducing energy consumption associated with lighting.
