8 Lighting Standards Tennessee Secondary School Athletic Association

9 Standards of Lighting The following guidelines are recommended by the Tennessee Secondary School Athletic Association. These standards apply to the lighting of all high school athletic activities sponsored by the TSSAA or its member schools. These standards incorporate the most current data available regarding the lighting, electrical and structural issues that apply to installation of a safe, effective lighting system. The standards are divided into recommended minimums and desirable features. The minimums establish criteria important to safe conduct of TSSAA activities and include evaluation of operating costs over the expected life of the lighting system. Desirable features are established to give added values where appropriate for a facility's needs. I. Recommended Minimum Standards These minimum standards are recommended for all lighting installations after the date of adoptions of these standards. Any modification in existing lighting systems after this date should be done so as to result in a lighting system in compliance with these standards. To be in compliance, a system must meet all recommended minimum standards. PART 1 GENERAL 1.1 LIGHTING PERFORMANCE The quantity of equipment needed is determined by the efficiency of the lighting system. Newest technology is capable of delivering equal or better results with as little as half the amount of equipment as typical floodlighting systems. A. Preferred Technology By utilizing a series of power adjustments, a lighting system is able to provide "constant light levels" and greatly extend the life of the lamps. In addition, this generation of lighting has high performance optic characteristics that enable reductions in the quantities of luminaires needed to meet design targets. B. Typical Floodlighting Computer designs are done using two sets of values. One predicts "initial light levels" when lamps are new. The other predicts "maintained light levels" after the lamps have passed through depreciation in light output. It is important to have the lighting designer use a maintenance factor adequate to account for this depreciation in light output throughout the life of the lamp. A value no greater than.70 shall be applied to initial light levels to predict these maintained values. Quality manufacturers are willing to provide guarantees of lighting performance. C. Performance Requirements Playing surfaces shall be lit to an average constant or target light level and uniformity as specified in the following chart. Lighting calculations shall be developed and field measurements taken on the grid spacing with the minimum number of grid points specified on page 12 of these standards with the light meter held horizontally 36 inches above the field surface. Measured average illumination level shall be +/- 10% of predicted mean in accordance with IESNA RP-6-01, and measured at the first 100 hours of operation.

10 Area of Lighting Baseball / Softball Average Constant or Target Light Levels (Horizontal) 50 footcandles - Infield 30 footcandles - Outfield Maximum to Minimum Uniformity Ratio 2:1 infield 2.5:1 outfield Football / Soccer / Lacrosse / Field Hockey / Rugby Less than 2000 spectators More than 2000 spectators Gymnasium / Basketball With spectators No spectators Natatoriums 30 footcandles 50 footcandles 80 footcandles 50 footcandles 2.5:1 2:1 2:1 Consult an experienced lighting manufacturer or lighting specialist Tennis Track Competitive Use General Use (Walking track) Combination / Multipurpose 40 footcandles 30 footcandles 5 footcandles Highest minimum for activities played on the field 1.7:1 within lines 2:1 principal playing area 3:1 N/A Lowest minimum for activities played on the field D. Glare for Participants To achieve placement of lights in positions that enhance playability, pole locations and fixture placements should be as shown on the layouts in the appendix. 1.2 ENVIRONMENTAL LIGHT CONTROL Many facilities are located near residential properties or roadways, creating the possibility of spill and glare onto adjoining properties. Consideration should be given to this issue during the initial lighting design stage to minimize this effect. Some communities are implementing ordinances designed to minimize light pollution. Contact your local planning committee or zoning board. The lighting equipment manufacturer can assist in assessing this issue and provide drawings showing maximum footcandles at any points of concern on adjacent properties. Do not hesitate to investigate a manufacturer's reputation, abilities, and past experiences in working with local authorities and private property owners regarding glare and spill issues. 1.3 LIFE-CYCLE COSTS Because the efficiency of lighting systems currently available can vary greatly, a life-cycle operating cost analysis should be considered when evaluating lighting systems. Owners should expect a quality lighting system to last a minimum of 25 years. These standards provide a Life-Cycle Operating Cost Evaluation form to assist with the process. Items that should be included are energy consumption based upon the facility's expected usage, cost for group and spot relamping and maintenance, and any additional savings in energy or labor cost provided by automated on/off control systems. Contract price and life-cycle operating cost should both be considered in determining a lighting manufacturer for the project. 5

11 1.4 CONTROL AND MONITORING SYSTEM A remote control and monitoring system will provide ease of operation and management for your facility. Manufacturers providing systems with a 25 year warranty will utilize this system to ensure your lighting performs as required. A. Remote Monitoring The system shall monitor lighting performance and notify manufacturer if individual luminaire outage is detected so that appropriate maintenance can be scheduled. The manufacturer shall notify the owner of outages within 24 hours, or the next business day. The controller shall determine switch position (Manual or Auto) and contactor status (open or closed). B. Remote Lighting Control The system shall allow owner and users with a security code to schedule on/off system operation via a web site, phone, fax, or up to 10 years in advance. Manufacturer shall provide and maintain a two-way TCP/IP communication link. Trained staff shall be available 24/7 to provide scheduling support and assist with reporting needs. The owner may assign various security levels to schedulers by function and/or fields. This function must be flexible to allow a range of privileges, such as full scheduling capabilities for all fields, to only having permission to execute "early off' commands by phone. Control unit shall accept and store 7-day schedules, be protected against memory loss during power outages, and shall reboot once power is regained and execute any commands that would have occurred during outage. C. Management Tools Manufacturers shall provide a web-based database of actual field usage and provide reports by facility and user group. D. Communication Costs Manufacturers shall include communication costs for operating the controls and monitoring system for a period of 25 years. E. Cabinet Construction Controls and Monitoring Cabinet shall be constructed of aluminum and rated NEMA Type 4. Cabinet shall contain custom-configured contactor modules for 30, 60, and 100 amps, labeled to match field diagrams and electrical design. Manual Off-On-Auto selector switches shall be provided. 1.5 WARRANTY AND GUARANTEE Product warranties are a good gauge of a manufacturer's confidence in their products. Warranties for typical floodlighting equipment can range from five years to 10 years, and details of covered items and conditions vary greatly. New generation technology comes with warranty periods of up to 25 years and includes guaranteed light levels, parts, labor, lamp replacements, energy usage, monitoring and control services, spill light control, and structural integrity. The manufacturer should have financial reserves to assure fulfillment of the warranty for the full term. It is highly recommended you consider these allinclusive warranties to limit your school's future exposure to escalating costs and maintenance hassles.

On a 4-pole design, the optimum pole locations are (.35 x field length) from center of field. 3. In general, football lighting standards apply to soccer with the following considerations: a. A corner kick is a specific visual task and general consideration should be given to facility design specifically for soccer. b. The corner grid point shall be lit to no less than 90% of the average light level. 4. For combination football and soccer facilities, soccer should take precedence. 5. Vertical aiming angles should be 21 degrees minimum. The angles are measured from below a horizontal plane at fixture height.

17 Glossary Aiming Angles The degrees below horizontal that light fixtures are aimed at the field. Angles are measured from a horizontal plane at fixture height. Critical in safe, playable lighting design. Ballast A transformer that delivers the proper operating voltage for high intensity discharge type lamps including metal halide lamps. Constant Light Levels The amount of light you can expect on the field at any given time over the life of the system. Footcandle The measurement of light on a surface. One footcandle equals one lumen spread over one square foot. Glare Light that interferes with the ability to see. Luminaire design, proper aiming angles, and pole locations are key to limiting glare for participants and spectators. IESNA Illuminating Engineering Society of North America. An organization that develops recommendations for sports lighting. Initial Light Levels The average light levels when your lamps are new. Manufacturers that do not provide constant illumination should provide scans showing what these levels will be. Lumen A quantity measurement of light, used mostly in measuring the amount of light a lamp develops. Metal Halide Lamp A lamp that generates light by passing electrical current through metallic gases. The first choice for sports facilities because of efficiency and color. NEC National Electric Code. A national safety code for electrical systems that is the basis for most local codes. NEMA Type A classification of reflectors. For example, a Nema 2 reflector gathers light in a narrow, focused beam, allowing it to be projected a long distance. A Nema 5 projects light a relatively short distance in a very wide beam. Most lighting designs use various combinations of Nema types to get the desired results. NFPA National Fire Protection Association. An organization that establishes and publishes various codes such as the Lightning Protection Code and the National Electric Code. Overturning Moment The amount of force applied to a lighting structure, mostly from wind. Pole foundations must be designed to withstand this force. Reflector Key element of lighting optics. It surrounds the lamp (bulb) and directs light to the field. The efficiency of the reflector is one factor that determines how many light fixtures you have to buy and maintain. Remote Electrical Enclosure A weatherproof enclosure that allows the electrical gear to be moved from the top of lighting structures to a lower point where it can be serviced easily. Smoothness The change in light levels between measuring points. The less change between points, the more even the lighting. (See also Uniformity.) Spill Light Wasted light that falls off the field or is projected into the sky. Systems that can re-direct spill light back onto the field save dollars and keep neighbors content. Target Light Levels The lowest average amount of light for which a lighting system should operate over its extended life to ensure performance requirements. Target values should be no more than 70% of initial values to be sure that lamp depreciation has been accounted for in the design. You should receive scans showing what this level will be.

18 Tilt Factor Most lamps generate fewer lumens when tilted off of either a horizontal or vertical position. Your design should show actual tilt factor used in your design. Underwriters Laboratories Independent, non-profit, product safety testing and certification organization. Visit for additional information. Uniformity The smoothness of light on the field. Also called uniformity ratio. A design criteria to assure that light is distributed evenly across the entire field. A max/min ratio of 2:1 means that the brightest point is no more than double any other point.
