WebCalculate the illuminance level on this point. Answer: E1 = 398 lux (from previous calculation in example#1) E2 = 291 lux (same calculation method as E1) Hence, Illumination from more than one source is added arithmetically. So, E total = E1 + E2 = 689 lux. WebNumber of fixtures = 3 x the number of footcandles needed x the square footage of the area divided by the initial lumens of the fixture (lamp) type x dirt depreciation. Example: Using 400 watt hps on 30' pole. 3 x 2 x 40,000 divided by 50,000 x 1.01 = 4.85. (Final fraction should be rounded up.) Required number of fixtures = 5.
