Outdoor Tennis Lighting
Proper installation will insure safe and effective lighting.
|Once the decision
has been made to install outdoor lighting fixtures at a new or existing
tennis facility, specific guide lines should be utilized to produce a safe
and effective finished project. LSI Lighting Systems, manufacturer of the
Courtsider Tennis Lighting System, provides guidance to all installers
of the CourtsiderTM system.
Initially, two important issues to consider are wiring and pole foundations.
Poles for the Courtsider system are available in anchor base and direct burial versions, both of which require an adequately sized concrete foundation. The anchor base model (see figure 1) utilizes four anchor bolts set into the poured foundation while the concrete is curing. The pole base plate is secured to the anchor bolts once the foundation has fully cured. Anchor bolts are generally 3/4"-1" diameter, and 30"-36" in length. A cardboard template serves as a guide for placing the individual anchor bolts to match the hole pattern of the pole base plate. Special attention should be paid to the recommended projection distance of the anchor bolts above the top of the concrete. This nformation is found on the template supplied by LSI and will allow enough projection of the bolt to thread the nuts on. Each bolt is supplied with two nuts and two washers. One nut and washer is threaded on each anchor bolt before the pole is set on the base, while the second nut and washer is utilized to secure the base plate after the pole is set. The bottom nuts are then adjusted as needed to plumb the pole.
The direct burial pole is furnished with an extended length of shaft (3') that is set directly into the foundation (see figure 2) before it has cured. The pole must be plumbed and oriented correctly before the concrete is set, since there is no mechanical adjustment.
The concrete foundation dimensions can best be furnished by a local consulting engineer. As a general rule, foundations for the CourtsiderTM should be no less than 18"-20" diameter by 48" in depth. This does not apply to areas of loose sand and gravel or other poor materials. The concrete should be a minimum strength of 4000 PSI, and should be poured in undisturbed soil. The entire length of the foundation must be reinforced with re-bar.
The size and strength of the poles is designed to handle the load of the light fixtures only. Therefore, the light poles should not be used as fence posts unless they have been designed specifically to support this additional load. Once the poles have been erected, the brackets and fixtures can be mounted (see figure 3). The CourtsiderTM system incorporates leveling mechanisms in both the bracket and fixture to insure uniform appearance. When installing lamps in the fixture, best contact between socket and base can be made by tightening, loosening, and tightening. Initially, the lamps in various fixtures may appear to be different colors. One hundred hours of operation are required for the lamps to stabilize to proper color output.
The final steps should include touching up any nicks or scratches in the painted surfaces at occurred during the installation process. If anchor base poles were used, the base covers should be set in place to cover the anchor bolts. Once the entire system has been energized, visually inspect each fixture for proper light output. Fixtures not operating, or those not at full light output could be a sign of faulty wiring, or defective lamp and ballast.
