Benefits of LED Flood Lights
What are the benefits of outdoor LED flood lights?
Outdoor LED lighting such as commercial LED flood lights provide some excellent benefits for exterior areas 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 outdoor LED Flood Lights:
Common wattages for commercial outdoor led flood light fixtures can range from 40 watts to 600 watts, often resulting in a 40%-60% reduction in energy consumption. The reason for this can be attributed to the “GENERATION” comments above, and can result in 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 fixture can be significantly longer than that of a HID Lamp, which in turn drastically reduces the costs for maintaining exterior flood 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 outdoor lighting fixtures for flood light 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 produce 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."
