Recommended illuminance level:
Horizontal illuminance: 20 fc. CV = 0.25 or less. (Emax/Emin = 3:1 or less)

American and Canadian Football Differences
Comparing Canadian and American Football
- Both share many similarities, with slight variations in rules and field dimensions. However, when it comes to illuminance criteria and design considerations, both versions of the sport align closely in ensuring optimal lighting conditions on the field.

POLE SPECIFICAITONS
Pole Quanity, Location, and Height
- Quantity
The number of lighting poles in a stadium can range from 4 to 8, with flexibility in their placement to avoid obstructing spectator views.
- Location
One common approach is to position the poles behind the bleachers. Alternatively, placing poles in the corners of major stadiums is also acceptable, eliminating the need for a long setback behind the grandstands. However, in a four-pole layout, taller poles and longer aiming throws for the floodlights may be required.
- Height
The specific height, offset, and setback of these poles are determined based on the stadium and site configurations to ensure optimal illumination while preserving the spectators’ experience.
