A Brief Guide to High Bay Light Fixture Spacing

March 19, 2021

Do you want to ensure your commercial and industrial bay has ample lighting? An excellent high bay light fixture is not the only thing you need.

These fixtures do provide high-quality lighting. However, the distance between them plays a significant part in lighting an area.

In warehouses, you need to ensure there’s adequate light for your workers to do their jobs right. Cold storage, on the other hand, needs lighting that doesn’t produce too much heat.

Correct spacing of high bay lights is not only about their distance from each other. Other factors such as height and area play crucial parts as well.

The setup doesn’t only ensure that critical areas receive ample lighting. It also allows for a cost-effective approach.

Here’s the two-step process to set up your high bay light fixture’s spacing:

Consider the Height

Proper spacing is dependent on the height of your commercial bay. Light is cone-shaped, spreading outwards the farther it travels from the light source. As the light spreads wider, its intensity weakens.

What should you do before determining the distance between them? First, you need to pick an appropriate LED light to provide ample lighting.

Lumens are a more accurate measurement of light intensity. You can get a low wattage light with high lumens.

As a rule of thumb, the higher the height, the higher the lumens you need. 

  • 10 to 15 feet height needs 10,000 to 15,000 lumens
  • 15 to 20 feet height needs 16,000 to 20,000 lumens
  • 25 to 35 feet requires lights with 33,000 lumens

Do you find LED lights with higher lumens too costly? You can opt to adjust the height using pendant lighting. This approach will help lower the height requirement and thus the lumens you need.

Use Proper Spacing

Your light fixture spacing is dependent on the brightness you need. You’ll also need to consider the height of the light source.

The following section is a quick guide on proper spacing. It shows details depending on the level of brightness and the installation height.

  • Installation height of over 15 to 20 feet: Needs 14 feet spacing for average brightness levels and 12 feet for high brightness.
  • 20 to 30 feet: Requires 18 feet spacing for standard and 16 feet for intense bright levels.
  • 30 feet: Needs 25 feet spacing for average brightness and 20 feet for high illumination.

When your fixtures are too close to each other, there’s an overlap that wastes energy. On the other hand, if you put them too far apart, the lighting is not adequate. With more significant gaps, you get uneven lighting at ground level.

While overlap is still essential, you only need a small degree. The actual amount of overlap depends on how much lighting you need on the ground.

Ensure Proper Distance Between Each High Bay Light Fixture

A proper high bay light installation is vital in achieving the required brightness. Follow this two-step process in spacing out your high bay light fixture. You’ll be able to achieve even lighting on your commercial bay.
