The standard deals with training and competition and takes into consideration spectator viewing requirements.
The standards contain information about maintained horizontal luminance (lux), minimum horizontaluniformities (U1 & U2) and maximum glare rating. These properties vary depending on whether the level of play is recreational, amateur or semi-professional.
Football NSW has adopted the National Standard (series 2560.2.3) as the basis for match lightingrequirements by football for affiliated competitions.
See the beginning of this guide for more information.
Illuminance Requirements of the Football Field Lights
The information outlined in this section is technical in nature. It is provided to make the reader aware of the standards and qualified lighting designers/contractors will then be able to plan your project.
Uniformity ratios are an important part of a complete set of lighting criteria and can have a positive effecton the quality of lighting installations. Adequate uniformity is required to create balanced lighting conditions so that people’s eyes do not have to continually adapt to a different light level of football stadium lights .
Minimum Horizontal of Football Field Lights
Uniformities are given in two ratios, each providing a numerical representation of the uniformity of illuminance over a given area. This may be expressed as a ratio of minimum to average (U1) or it may be expressed as a ratio of minimum to maximum (U2) level of illumination for a given area. For example, (U1) club competition and match play minimum uniformity equals 0.5. The lowest level of illumination should not be less than 50% of average (U1) or 30% (U2) of the maximum level of illumination.
