Benefits of LED
What are the Benefits of LED Wall Pack Lights and LED Building Lights?
Industrial LED lighting, commercial LED lighting, LED retail lighting, lighting for storage facilities, or any other applications, can realize significant benefits 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 light 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.
Common wattages for LED wall pack fixtures can range from 24 watts to 82 watts, often resulting in a 40%-60% reduction in energy consumption. The reason for this can be referenced 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 product can be significantly longer than that of a HID Lamp. For example, by converting a conventional 250w HID wall pack to an LED wall pack, a typical facility with exterior building lights can save up to $5,341 over the course of three years in maintenance costs alone.
Moving on to the way LED fixtures “DISTRIBUTE” light, as a result of the multi-point design, LED wall pack lighting applications often provide very evenly distributed light. What this means is that light levels across a given surface will vary less between fixture mounting locations. This is when compared to HID fixtures, which often produce a “bright spot” directly underneath the fixture with light levels decreasing drastically as the distance between fixtures increases. 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 CCTs (correlated color temperatures), and as a result provide a range of options to increase the visual perception of “brightness."
