Schools & Collegiate - Intramural
How to light your field.
Scholastic fields can be and are the pride of communities. Each one has its own set of parameters and no two fields are exactly alike. When decisions are made to light them, proper care should be taken to ensure you have the showcase you want. Specific average maintained illumination levels are required and should be researched either through local ordinances, scholastic organizations or the Illuminating Engineering Society of North America (IESNA) "Recommended Practice for Sports and Recreation Area Lighting, "RP-6-01 manual.
Intramural sports for collegiate or even at the scholastic level again pose their own set of needs. Typically, intramural fields are large open areas that have many sporting fields located inside the perimeter. Care should be taken so the area does not get too large that extremely tall poles are needed which will add costs to your project. They are usually lit to one overall average maintained footcandle level and can vary in average intensity. Local schools and colleges should work with architects and engineers or lighting manufacturers to establish these levels.
Steps to follow
Determine the sport, class of play and foot candle / uniformity requirements listed below.
Select the optics. Be sure to research local municipal codes for spill/glare requirements to ensure you use the proper optics.
Select the lamp source and wattage. The lamp source for sports lighting venues is Metal Halide. For most sporting events, 1500W is the desired wattage since fewer fixtures are required. However, for outdoor tennis courts or indoor sporting events, 1000W may be a better choice. Lamp life for 1000W is 12,000 hours whereas 1500W is 3,000 hours.
Select the systemů. Remote ballast pre-wired and pre-aimed or integral ballasted pre-wired. Remote systems usually are wired and pre-aimed and can save installation time and costs. Integral ballasted systems are pre-wired and the luminaires are field aimed for greater accuracy to the lighting design. Integral luminaires are mounted to existing poles or poles supplied by the end user. They will require aiming and wiring in the field. Retrofitting these luminaires on existing poles will save money simply by not adding the extra costs associated with poles. Please note that it is the responsibility of the end user to insure the structural adequacy of the poles/structures not supplied by Hubbell Lighting.
Select the pole type. Galvanized steel poles are the most common in sports lighting applications with concrete a very good option for some areas.
Contact a local architect / engineering firm or lighting manufacturer with experience writing product and performance specifications for sport fields.
Competition play before a large group (5000 or more spectators). However,for the purpose of this practice, illumination criteria for individual sports are limited to a spectator capacity of 10,000 or less. Lighting criteria for major stadiums and arenas require special design considerations such as vertical and horizontal illuminance values not covered by this Practice, which may be defined by individual sports and/or broadcasting organizations.
Competition play with facilities for up to 5,000 spectators.
Competition play with some spectator facilities
Competition or recreational play only
Why Choose SLS?
With Sportsliter's advanced engineering, fewer fixtures are needed overall - which results in lower installation, maintenance and energy costs in the long run.
