LED Low bay lights are usually installed at a mounting height in lower ceiling applications, between 12 to 20 feet above the floor. Since they are lower to the ground, less power is needed to light up the space than its twin high bay light. Optics on low bays distribute the light evenly. By using optics to direct the light, lighting uniformity can be accomplished. Low Bay lights typically are equipped with wide beam angle optics of 90° to 120°.

What Is Low Bay Lighting?

Low Bay lighting is a lower powered version of high bay lighting. It is designed to be mounted on ceilings no higher than 20 feet. A high bay in this area would be too powerful and too bright.

What Is the Difference Between a High Bay and Low Bay?

The main difference between the two lights is the power and beam angles. Low bay lights are lower powered versions of high bays. Also, high bays sometimes have options to decrease the beam angle or optic, something you would do at higher mounting heights. In a low bay, you would never install a tighter beam angle. Low bays work best with the widest beam or optic patterns, 120 degrees or better.

How High Is Low Bay Lighting?

The maximum height is around 20 feet. If you need to install a light higher than that, you should use a high bay fixture.

What Are the Different Types of Low Bay Lights?

Today’s low bays are typically one of three styles:
1. UFO Style – these round fixtures are designed to be a replacement for metal halide fixtures;
2. Linear Panel Style – these lights are similar to fluorescent lighting low bays.

What Are the Benefits of LED Low Bay Lights?

Over their metal halide and fluorescent counterparts, LED low bays offer a plethora of benefits:

energy savings between 50% and 90% (when controls are used);
significantly lower maintenance costs over a period of 10+ years;
the ability to add energy savings controls (like motion sensors) that dim the lights when the area is empty and void of activity.

What Determines Low Bay Lighting?

These are typically lowered power high bay fixtures. For example, we have a line of high bays designed to replace 400 Watt metal halide. They are 120 Watts, 150 Watts and 200 Watts. The 100 Watt version of this fixture is the “low bay” light.

Do Low Bay Lights Have the Same Spread as High Bay Lights?

They can, but as mentioned above, it’s not advisable to install a tighter beam angle on a low bay light mounted below 20 feet. It would create a powerful beam of light directly under the fixture, but then create underlit areas in between lights.

How Do I Dim These Fixtures?

Make sure the fixture you have includes a dimmable LED driver. They are typically either 0-10V or 1-10V and require an independent dimmer control to dim the fixtures. Contact us for assistance if you need to dim the fixture.

How Do You Install Low Bay Lights?

There is nothing difficult about installing a low bay fixture. We have many mounting options, and there are only 3 wires to connect, line, neutral and ground.

How Do I Get Rid of the Shadows Between My Fixtures?

A good rule of thumb is: more, less powerful lighting closer together is better than less higher power fixtures. The former will provide more balanced lighting and less shadows.
