Low Bay Lighting

What to Look For in Low Bay Lighting

Low bay fixtures are optimized for closer mounting heights, generally below 20 feet. Key factors include mounting height range, beam angle (typically wider than high bay fixtures to maintain even floor coverage at closer range), and fixture spacing requirements to avoid dark spots or excessive overlap. For harsh or hazardous industrial environments, ingress protection and classification rating are equally important.

Low Bay vs. High Bay Lighting

The core distinction is mounting height:

• Low bay lighting is designed for ceilings below 20 feet, using wider beam angles suited to closer-range illumination.
• High Bay Lighting is designed for ceilings 20 feet and above, using higher output and typically narrower beams to maintain light levels at greater height.

Selecting the wrong category for your space typically results in uneven coverage or inefficient light distribution.

Where Low Bay Lighting Is Used

• Smaller warehouses and storage facilities — even coverage in lower-clearance layouts
• Maintenance and service areas — consistent task-level illumination
• Lower-clearance industrial buildings — facilities where structural height limits mounting options
• Hazardous-location facilities — classification-rated low bay fixtures for processing environments under 20 feet

Choosing the Right Fixture

Confirm your actual ceiling or mounting height first — this is the primary factor separating low bay from high bay fixture selection. From there, determine fixture spacing based on beam angle and desired light levels, and verify classification rating for any hazardous-location installation.
