(Eye peak at 555 nanometers) SCOTOPIC VISION At even lower illumination, giving completely black and white vision. Nighttime adaptation. (About 400 nanometers) MESOPIC VISION The overall appearance is less colorful under lower illumination level, like those of streetlighting or moonlight. (505 nanometers)

history importance definitions criteria Dialux 4.6 Calculation by Lumen Method: The average illuminance produced by a lighting installation or the number of luminaires required to achieve a specific average illuminance, can be calculated by means of utilization factors. The average illuminance E s over a reference surface s can be calculated from the “lumen method” formula. F x n x N x MF x UF s E s = ------------------------------ area of surface s where: F is the initial bare lamp flux (lumens, lm) n is the number of lamps per luminaire N is the number of luminaires Uf s is the utilization factor for the reference surface s MF is the maintenance factor (dirty: 0.7, normal: 0.8, clean: 0.9) ,[object Object]

He wants to mount his luminaires on the trusses 8m above finish floor line. What type of luminaire will he use and how many of those will he purchase? Given: L = 20m, W= 30m, H = 8m, MF = use 0.8 Reflectances (use default) : C = 0.7 W = 0.5 F = 0.2 Solution: To obtain UF, solve for Room Index (RI) = A/(L+W)Hw, RI = 1.5 Required Average Illuminance (Eave) for warehouse as per standard is 100 lux ,[object Object]

From UF table of Thorn High Bay, UF = 0.78 Substituting to equation: F x n x N x MF x UFs E = ------------------------------ A (100)(600) N = ------------------------------- (27500)(1)(0.8)(0.78) N = 3.49, use 4 sets 250W SON-T high bay lighting fixture Checking the lighting level, E = 114.4 lux ,[object Object]
