I’d like to find some online and free consultation about copyrights/trademark issue. I want to publish/republish something which might infringe with the copyrights of an institution. However, It may not be me who is publishing, rather the users/members of my site may publish such resources which may infringe with the copyrights. How is it gonna affect me if I do have a disclaimer on the site. A lawyer online who can assist me in finding the answer will be very helpful.

Tennis Court Lighting Fixtures

R. Neal asked:

The best tennis court lighting fixtures are forward throw fixtures that feature either precision optics or cut off designs that focus illumination on the court and minimize glare from surrounding viewpoints. Tennis court lighting systems should always be designed with two simultaneous objectives in mind: lighting the court and lighting the ball in play. Optimal illumination depends on striking this balance, and this balance in turn depends upon several other factors as follows:

1. The number of light poles

2. The physical location of lighting poles

3. The type of lighting fixtures attached to poles

4. The number of fixtures per pole

5. The proper number of footcandles

6. The purpose of the court

7. The physical size of the court

When each of these factors is properly balanced against the other, a uniform distribution of the light and non-glare optics can be created. Optimal tennis court lighting should cover the entire court and extend approximately 6′ beyond the sidelines and 10′ behind the base lines. Metal Halide luminaries are the most common HID source used for tennis court lighting.

Selecting the Right Tennis Court Lights, Poles, and Accessories

Customers can find individual lighting fixtures, supplies, and individual light poles and lamps in our online store. Typically, tennis lighting fixtures come equipped with a 1000 watt, Metal Halide bulb. These sports lights are manufactured for both residential and commercial applications, so customers have the flexibility of installing these devices in a variety of settings. RLLD Commercial tennis court lighting pole sizes come in a variety of heights and can be used with narrow, tournament, and club size tennis court playing fields. For the convenience of both professional designers and certified electricians contracted by homeowners, we have developed tennis court lighting packages that are specifically approved and designed for six standard tennis court layouts.

A few additional points bear further notice. Some of our tennis court lighting kits come with a double lamp pole light fixture. This creates a more evenly spread illumination and a different look compared to the conventional single lamp pole. We also have quad light poles that have four die cast light fixtures for a distinctive appearance. RLLD Commercial Lighting includes all necessary accessories for these lighting kits, include mounting hardware, brackets, and lamps. RLLD Commercial Lighting tennis court light kits can also be used with basketball and volleyball courts, or any other type of athletic or sports lighting area that requires superior lighting for game purposes.

Tennis Court Fixture Mounting Methods

In tennis court lighting you can choose between low-mast and high-mast pole configurations. Generally speaking, residential tennis court lighting is better accomplished with low-mast lighting, while high mast lighting is used in areas where higher light levels are required. Low-mast systems used in conjunction with sharp cut-off luminaries produce good uniformity, low glare, reduced amounts of spill light and are relatively easy to maintain.

Country clubs, resorts, five star hotels, and municipal parks can select from over 40 sports lights specifically designed for tennis courts.
