A light tube is 872 mm long. Determine the distance (W) between a light tube and a side of the aisle
based on the actual length of the contained aisle in the module: W = (L – 872 x N)/2. L is the actual
length of the contained aisle. N is the number (round down the value of L/872) of light tubes installed in
a single row. Round down the value of W.
 A maximum of 12 aisle lights can be connected in series. If the number exceeds 12, they should be
installed in different groups.
 Redundant LED indicators are delivered.
