There are a few things that are important to consider when shopping for an LED High Bay or Low Bay light.
1) Not all high bay lights are created equal. Contrary to your traditional incandescent and metal halide lights, LED light output is actually measured in Lumens - not Watts. This means that all 150W high bays do not produce the same amount of light. Tip! The more lumens, the more light the fixture will put out!
2) It is also important to know how high the fixture is going to be hung, as this will help you decide how many lumens you will need.
3) The shape of the fixture you need is largely dependent on your application and intention of use.
4) Lastly, you will need to decide what color temperature (CCT) is ideal for you. Most LED high bay / low bay lights are configured between 3000K to 6500K.
There are 2 types of LED bay lights: high bays and low bays. While they are basically the same fixture, each feature a different beam angle and are installed at different heights. High bay lights are mostly found in commercial spaces with ceiling heights 15 feet and higher. You might see them in warehouses, basketball gymnasiums, and hangars. Low bay fixtures are more commonly found in retail stores, grocery supermarkets, and workshops.
Aside from the fixture's shape, the main difference between a round and linear high bay or low bay light is the light distribution. The round LED fixture will yield more of a circular beam spread while the linear LED light produces a more rectangular shape. The other difference is in application. While linear fixtures are best suited for a more uniform lighting effect, like in corridors and warehouse shelving, round fixtures are better suited for open spaces like gymnasiums and hangars.
Once you've chosen the best LED high bay / low bay light for your application, you'll want to figure out how many fixtures are needed to properly illuminate your commercial space or barn. Depending on how much light you want, a good rule of thumb is to use 3-5 lumens per cubic feet (cuft.)
Let’s assume your warehouse space has the following dimensions (Length X width X height:) 50 ft X 50 ft X 20 ft.
Solution: For a 50 ft X 50 ft warehouse space with a 20 ft ceiling height you would need six 150W high bays installed in a 2 by 3 grid spaced equally.
