Briefly turn the laser back on or re-check view through tube to verify that the luminaire aim did not shift during

tightening.

Remove the laser mount from the fixture and proceed to the next luminaire.

Final aiming:

Aiming information is exported from computer lighting simulation software. Since on site conditions may vary from the

computer models, final aiming is usually required to fully achieve desired lighting specifications. Final aiming means deviating

from designed aiming parameters to produce the best outcome on the playing surface. Typically, final aiming only requires

slight adjustments.

Verify that all lights are correctly aimed according to the photometric or installation drawings.

Measure light levels on the playing surface using a calibrated light meter. Unless otherwise noted, take readings at 3'

above ground, holding the meter out at arm's length as much as possible, thereby reducing the effect of the shadow

from your body.

Take horizontal readings by holding the meter face up, parallel with the ground. Take Vertical footcandle readings by

otee:

facing the meter at a perpendicular angle to the floor toward the vertical main or vertical end point. These vary based

on venue and sport, but basically refer to the typical locations for elevated main cameras, at the center lines directly

off of the side and off of the end of the playing surface.

Refer to specific project requirements or governing league regulations for more information. For reference, the NCAA lighting

best practices website has grid layouts by sport:

Review the light measurements and compare the data to project requirements or photometric drawings. If the light

measurements do not meet designed levels, final aiming is required.

otee:

There is no hard and fast rule on how to make final aiming adjustments as it is essentially an art form due to the

propagation and reflection properties of light. A bright spot is usually not caused by one individual luminaire but rather

the additive effect from several luminaires aimed in the same general vicinity.

Note the areas of the playing surface that are the brightest and darkest and determine which luminaires are aimed

toward the bright areas and which are aimed near the darkest areas.

Re-aim one or a few lights away from the bright areas and closer to the darker areas.

During final re-aiming, always minimize the number and size of aiming modifications. Make just one or a few small

adjustments and then re-check light levels. Making too many significant aiming changes may result in failure to meet

specified levels or introducing unwanted results such as glare.

Re-measure light levels in areas where adjustments were made and compare new results to project specifications.

Repeat steps 5-6 as necessary to meet light level requirements.

Step 5 – Finishing Touches

To complete the installation, verify that all mounting, connection, and aiming work is finished.

Verify all electrical connections are tight and secured. The installer is responsible for the integrity of all connections.

●

Verify all bolts and screws are tightened and properly torqued.
