Luminaire InformationThe metal halide wall washer that was used for this calculation is a large, semi-recessed, wall washer. The overall dimensions of style 204 are 9-5/8" (wide) x 18-3/8" (long) x 8-3/8" (tall). The luminaire is by Elliptipar and the catalog number is M204-400-T-02-U-00-0.
Lamp InformationThe IES file for this luminaire uses one 400W clear T-15 "Super" Metal Halide in the horizontal position. To determine the LLD I used a metal halide lamp from Standard order code 58076.
Ballast InformationTo determine the ballast factor I used a Metal Halide (Pulse Start) from Holophane.

Zone DataFrom the table on the left we can see that there is less 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.
