Lighting Power Density: 0.63 Watts/Sq. FT
General Note: Food serving areas are required to me 40 foot-candles on average with and are allowed 0.92 Watts/Sq. FT for the examples below I have excluded serving areas as the dimensions and placement vary too much from school to school to give a fair typical. I’m confident we can raise the light output on any of the fixtures below to meeting food service requirements.
