  Lumen Rating: the unit of measurement used to indicate the quantity or intensity of any lamp. Think of it in terms of the lamps raw power. Lumens are measured at the lamp. Lumens are used in the lumen method calculation to determine the number of fixtures necessary and their spacing to maintain a given foot candle level as prescribed by IES (Illuminating Engineering Society.)

Notes:

  1. Maintained horizontal foot candles is determined by applying a light loss factor (LLF) to the initial calculated or measured foot candles.  LLF is dependent upon lamp characteristics, fixture design, fixture maintenance, voltage variations and atmospheric conditions.  It normally varies between .60 and .85. 
  2. Average maintained and minimum maintained horizontal foot candles should be calculated within the playing lines and/or within the Primary Playing Area (PPA) determined by the specifications of the project with foot candle values multiplied by the appropriate LLF.
  3. Uniformity ratio is defined as the ratio of maximum foot candles divided by the minimum foot candles.
  4. Primary Playing Area (PPA) is defined as the area that includes 6′ beyond the sidelines and 10′ behind the baseline.
