The aiming diagram provided by the factory details the locations of
luminaire aiming points. It is helpful to predetermine the correlation
between a particular aiming point and the associated fixture location in
the cluster or cage. Luminaire number information is provided in the
aiming diagram for this purpose. When marking the luminaire aiming
point on the field it is suggested that a numbered survey flag be used
corresponding to the proper luminaire.
Luminaires should be energized prior to starting the point aiming
process. It is possible for experienced personnel to aim luminaires
without having them lit, but it is much easier (even during daylight
hours) to do this when they are lit.
To aim a luminaire, locate the appropriate luminaire and corresponding
aiming point. Starting at the aiming point, walk toward the current
luminaire, stopping when your head casts a shadow on the aiming point
(flag) as shown in Figure 1.
