Achieving 100 Footcandle Lighting
The chart in this guide shows the number of fixtures needed to light various room areas with 100 foot-candle brightness, factoring in mounting height and room width.
Number of Fixtures needed = Room area (sq ft) / sq ft per fixture
(Assumes Good Reflectance)
- Room Factor:
- W - width = 4 x Mounting Height
- M - width = 2 x Mounting Height
- N - width = Mounting Height
