Often mounted higher than recessed troffer or fluorescent surface lighting applications, High Bay fixtures and Low Bay fixtures are used in building with higher ceilings to provide warehouse lighting, industrial lighting, commercial lighting, retail lighting, and gym lighting.
Industrial LED Lighting, Commercial LED Lighting, LED Warehouse Lighting, or any other applications using LED High Bay Lighting are able to 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 high bay fixtures can range from 95 Watts to 495 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.
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 an HID Lamp. For example, by converting conventional 400w HID High Bay Lighting to LED, a typical building with industrial light fixtures can save up to $5,341 over the course of 3 years in maintenance costs alone.
Moving on to the way LED fixtures “DISTRIBUTE” light. As a result of the Multi-Point design, LED High Bay 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. Compared to HID fixtures, which often product a “bright spot” directly underneath the fixture with light levels decreasing drastically as the distance between fixtures 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 CCT’s , and as a result provide a range of options to increase the visual perception of “brightness”.
