For those who need to light a large interior space, high bay lighting is often the best option. High bay lighting is designed to provide brighter, more focused light over large areas, and is used in spaces like warehouses, gymnasiums, and industrial facilities. But how is high bay lighting calculated?
There are a few key factors that go into calculating high bay lighting needs. First, you need to consider the size of your space. High bay lighting is typically used in areas with ceilings 20 feet or higher, so the height of your ceiling will be a major factor in determining your lighting needs. The square footage of the space will also be a factor, as you'll need a certain amount of light output per square foot to ensure adequate lighting.
The type of space you're lighting is another factor to consider. For example, a warehouse may require brighter lighting than a gymnasium, as the work being done in a warehouse may require greater visibility. Similarly, the type of fixtures you choose will affect your lighting needs. LED fixtures, for example, may require fewer fixtures than traditional fixtures to achieve the same level of brightness.
Once you have a sense of your space, you can start to calculate your lighting needs. The first step is to determine your desired foot-candle level. Foot-candles are a measure of how much light is hitting a surface, and are calculated by dividing the lumens of light output by the square footage of the space. A general guideline is that most high bay lighting should provide between 30 and 50 foot-candles of light, but this can vary depending on the type of space and the activities being done there.
Once you know your desired foot-candle level, you can start to choose the appropriate fixtures and bulbs. LED fixtures are generally the most efficient and long-lasting option, and can provide the brightness you need while consuming less energy than traditional fixtures. You'll also need to consider the beam angle of your fixtures, as this will affect how widely the light is distributed.
Finally, it's important to note that high bay lighting is typically installed by a professional electrician. A professional can help you determine your specific lighting needs, choose the right fixtures and bulbs, and ensure that your lighting is installed safely and correctly.
In conclusion, calculating high bay lighting needs involves considering factors like the height and square footage of the space, the type of space and fixtures, and desired foot-candle levels. By taking these factors into account and working with a professional electrician, you can ensure that your high bay lighting provides the brightness and efficiency you need to keep your space well-lit and safe.
