Frequently Asked Questions
A1: LED stands for Light Emitting Diode.
similar way as ICs “chips”, which are used in computers and phones. Therefore an LED is reliable, but will also have a very good price/performance curve over the years. In other words, they will give much more light for a lower price over the years. Currently, the light output of LEDs, compared with Metal Halide Lamps, is similar on a Total System Power basis.
A2: LED fixtures are directly switchable on-off-on-off-… and switch immediately to the requested light level.
This means that user-friendly electronic control is possible. LED Luminaires use less energy than conventional sports field luminaires because you will only need to switch on the lighting when it is needed, at the light level requested at that moment. JASSTECH LED Luminaires can also be dimmed to deliver various preset scenes, without compromising uniformity of illumination over the playing surface or space. Old style conventional lighting find this very difficult because they need to turn luminaires off, and this affects the life of some lamps.
Lighting for Sports and Public Lighting in Australia and New Zealand is guided by:
- AS/NZS 2560.x Guide to Sports Lighting
- AS/NZS 1158.x Lighting for Roads and Public Spaces
- AS/NZS:4282 Control of the Effects of Obtrusive Lighting
- Various sports governing bodies.
These standards were developed to ensure the safety and enjoyment of the game for the athlete. They are very strict in terms of the amount of light, evenness (uniformity of the light) and light colour authenticity. In general, Sports Lighting standards are considered more rigorous than Road and Public Space Lighting, and are therefore more difficult to satisfy for a standard floodlight luminaire.
In order to demonstrate compliance to the relevant standard, JASSTECH will prepare a illumination design for your peace of mind. JASSTECH can also assist with the Development Application and approval by local authorities and governing bodies.
- Sports fields illuminated by JASSTECH are able to deliver AS2560 compliant illumination for all levels of play, from amateur training to professional match play.
- JASSTECH also ensures that all designs consider AS4282 (Control of the obtrusive effects of lighting)
A5: The short answer is there are hundreds of installations. We only provide luminaires from well established companies.
JASSTECH commissioned its first installation of sports lighting in 2012. Since then there has been over 250 very successful installations, with the number of projects installed in Australia and New Zealand growing rapidly. We have the longest experience of any LED sports lighting company in Australia, and we know what works.
LED lighting is perceived as much more pleasant (dependent on colour temperature), because the whiter (more ‘crisp’) light colour, which more closely mimics daylight. Players who have enjoyed a game under the JASSTECH luminaires confirm that they experience better contrast on the ball, the lines and the opponents. This enhances player performance and playing enjoyment, but also contributes very well to the fact that high balls are easier to be seen and followed.
JASSTECH also provides a guaranteed illumination performance for 25,000 hours – with only three per cent lumen depreciation over this period. Old style Metal Halide sports lighting starts depreciating as soon as you turn them on for the very first time. After two years metal halide customers often report of failed lamps and non-compliance to Australian Standards.
INFRASTRUCTURE and OPERATION
A7: Yes, this is possible.
The JASSTECH range of sports and public space luminaires have similar sail area (windage) and mass (in kilograms) as an old style luminaire. In fact, the major pole manufacturers confirm that our luminaires are suitable for a conventional pole and footing design.
You will need to check, however, that there hasn’t been any additional load put on the pole prior to the installation of JASSTECH luminaires. You can do this by engaging an engineer, contacting the pole manufacturer, procuring plans from the site owner, and/or your local council. The cabling and the mast positions is never an issue, because we actually provide the same illumination but for less electrical load.
