Zone DataFrom the table on the left we can see that there is slightly higher than a 20% difference from every point to the average of that zone. This tells us that we have a fairly evenly illuminated wall in each of the 6 zones. The minimum values for each zone are so much lower than the maximum and average illuminance values for each zone because thy are located at the edges of the wall. Since the fixtures are 3.5' o.c. from the edge of the walls we start to see some dark spots at the top and bottom corners of the wall. In between some zones we can see about a 33% increase in the average illuminance values. This may produce a noticeable change in illuminance from the top of the wall to the bottom of the wall.
