Outdoor Sports Lighting is a type of site light fixture that is commonly used to illuminate large areas for sporting events or large out events and activities. Sports Light Fixtures are typically mounted on poles 40ft to 100ft tall, with 1 to 12 fixtures mounted on each pole. This type of outdoor lighting is often used by schools, colleges and universities, municipalities, amateur sports clubs, and professional sports franchises.
Outdoor LED Lighting, such as LED sports field lighting fixtures, provide some excellent benefits for large areas or sites requiring illumination because of how they GENERATE light and how they DISTRIBUTE light. Light Emitting Diodes generate light via a semi-conductor, as opposed to the consumption of a “fuel source” like in HID lamps. In regards to “distributing” light, LED fixtures commonly utilize “Multi-Point” sources, meaning the fixtures have Multiple Diodes with individual optics. When you compare this to the way most HID fixtures distribute light (with a single bulb and reflectors within the fixture), the result is light that is more EVENLY “distributed’ across a given area.
The three most common benefits of LED Sports Field Lighting:
Common wattages for LED Sports Field light fixtures often range from 209 Watts to 750 Watts, often resulting in a 50%-80% reduction in energy consumption. The reason for this can be referenced to the GENERATION comments above, and can result in savings of up $8,000 per fixture per year in electricity cost.
Maintenance Cost Reduction
Again, due to the way LEDs generate light, the way they progress through their functional life is much different. Instead of ceasing to function properly once a fuel source is significantly reduced, LED generated light output degrades VERY SLOWLY over time. As a result the functional life (often in excess of 100,000 hours) of an LED fixture can be significantly longer than that of an HID Lamp, which in turn drastically reduces the costs for maintaining exterior high mast light fixtures over a longer period of time.
Moving on to the way LED fixtures DISTRIBUTE light. As a result of the Multi-Point design, LED sports field fixtures for site and large area applications often provide a very EVENLY distributed light pattern. What this means is that light levels across a given surface will vary less as the distance from the pole or fixture changes. Compared to HID fixtures, which often product a “bright spot” directly underneath the fixture with light levels decreasing drastically as the distance from the pole increases. The result, in regards to LED vs HID, is a more even foot candle distribution from the LED conversion. In addition to the even distribution of light, LEDs are available in a range of color temperatures, and as a result provide a range of options to increase the visual perception of “brightness."
