Problem: There were concerns that light leakage could disturb Kitt Peak Observatory since the installation would make the field the brightest spot in a geographic region that historically had been very dark.
Southwest Energy Solution: Before each of the eight, 80-foot poles were erected, crews assembled and mounted an average of 11 fixtures on each lightning rack from the ground. Carefully adhering to factory specifications, SES crews mathematically set the shades and light lamps according to their position around the field.
When the poles were placed into position, and the lights turned on for the first time, not a single light required adjustment after installation, a first for the manufacturer. This precision accuracy of assembling the lighting from the ground allowed the project to be completed ahead of schedule. And with the lighting focused on the field, Kitt Peak reported minimal disturbance to its telescopes.
