Benefits of LED Lighting
Benefits of LED Parking and Area Lighting Applications
Outdoor LED lighting fixtures, such as exterior LED parking lot lights, provide some excellent benefits for parking and area applications 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 surface.
The Three Most Common Benefits of LED Parking Lot Lights:
Common wattages for LED parking lot lighting can range from 40w to 600w, often resulting in a 40%-60% reduction in energy consumption. This is a result of how the light is generated (see above). What this means for your facility is savings of up $300 per fixture, per year, in electricity costs.
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 product can be significantly longer than that of a HID lamp, which in turn drastically reduces the costs for maintaining a parking and area fixture over a longer period of time.
Moving on to the way LED fixtures “DISTRIBUTE” light: as a result of the multi-point design, LED outdoor lighting fixtures for parking and area lighting applications 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. HID fixtures often produce a “bright spot” directly underneath the fixture with light levels decreasing drastically as the distance from the pole increases. LEDs mitigate this problem through even distribution. The result, in regards to LED versus 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.”
