NOTES:
| |
1.
|
Illumination levels are maintained horizontal footcandles on
the task, e.g., pavement or area surface.
|
2.
|
Uniformity ratios dictate that average illuminance values shall
not exceed minimum values by more than the product of the minimum
value and the specified ratio, e.g., for commercial parking high activity,
the average footcandles shall not be in excess of 3.6 (0.9 x 4).
