Recommended Mounting Height

 • Optimal Brightness: Up to 15ft ceilings.

 • Above 15ft: Light output per square foot decreases. To fix this add more fixtures, or upgrade to our 6-lamp LED light fixture for more light output.

 • Below 12ft: If your mounting height is below 12 feet, our 4-lamp frosted LED fixture delivers evenly diffused light that’s easy on the eyes. For those who want maximum brightness at lower ceilings, consider our 4-lamp clear LED fixture.

 

How Many Shop Light Fixtures Do You Need?

Lighting layouts vary by application, but here are our recommendations to ensure bright, shadow-free coverage:

 • The lower end of each range provides sufficient light for general use.

 • The higher end of the range delivers brighter coverage, perfect for tasks like detailed work, welding, or automotive projects where shadow reduction is critical.

In other words, the more fixtures you choose within the recommended range, the brighter and more uniform your space will be.

 

Small Shops & Garages

2-Car Garage - 400–500 sq ft → 4-6 fixtures

3-Car Garage - 600–750 sq ft → 6-8 fixtures

 

Medium Shops & Barns

1,000 sq ft (25’ x 40’) → 8-12 fixtures

1,500 sq ft (30’ x 50’) → 10-15 fixtures

Large Workshops & Warehouses

2,500 sq ft (50’ x 50’) → 16-24 fixtures

5,000 sq ft (50’ x 100’) → 28-40 fixtures

Rule of Thumb: 1 fixture per 100-125 sq ft at 15ft ceilings.
