In the field of lighting, high bay lights are a widely used light fixture, you can find it in warehouses, factories, gymnasiums or any large open area with relatively high ceilings. Many existing high-bay and low-bay lamps use high-intensity discharge lamps (HID), such as metal halide lamps or high-pressure sodium lamps. Although HID lights are widely used, they use outdated technology, which directly or indirectly imposes costs on building managers. Specifically, the use of HID lamps will result in: higher than necessary energy costs, frequent maintenance costs, and poor lighting performance. These problems can all be solved by converting your existing lighting to LEDs.
Energy efficiency is the main driving force behind your evaluation of LED lighting for your building or facility. Common wattages for LED high bay lights can range from 95 watts to 495 watts. If we compare this wattage to a typical HID overhead fixture, the same range is 175 watts to 1000 watts. Therefore, by switching to LED lighting, you can immediately reduce energy consumption by 40%-60%. Converted to dollars, you can save $300 per fixture per year on your electricity bill if you switch to LED lighting. Depending on the size of the plant, that does impact the operating balance sheet.
You will also see a significant reduction in maintenance on your high bay lights by converting to led lights. This is due to the way LEDs emit light, and their long lifespan. The light output produced by LEDs will drop very slowly over time, rather than stop functioning properly once the fuel source is significantly reduced. As a result, LED products have a much longer lifespan than HID lamps, thus significantly reducing the maintenance load required. For example, by converting traditional 400w HID high bay lights to LEDs, a typical building with industrial fixtures can save $5,341 in maintenance costs alone over a three-year period. Finally, lighting performance is a key factor in evaluating options for different types of lighting.
From a performance point of view, LEDs are much higher than HIDs. The LEDs are multi-spot designed, which means they distribute the light evenly over the intended surface. As a result, there is less variation in light levels between where the luminaire is installed on a given surface. In addition to an even distribution of light, LEDs also have a range of CCTs (correlated color temperatures), thus offering a range of options to increase the visual perception of “brightness”. Conversely, HID fixtures create a “bright spot” directly below the fixtures, and the brightness of the fixtures drops off dramatically as the distance between the fixtures increases.
In summary, we can see that there are three main drivers to consider installing LED retrofits in your facility. By switching, you’ll see immediate energy savings, less frequent lighting maintenance, and improved overall lighting performance.
