i’m missing something. # fixtures = total illumination (Fc) x floor area (sf) / lamp lumens? if i am given 3 bulbs in a fixture and 15 Watts per bulb - how do i get the lamp lumens? THANKS

  I am not sure if this answers your question, but the efficacy of the fixture is equivalent to lumens / watts. If you know the total wattage and the total efficacy of the fixture you can calculate for lumens.
