A properly designed warehouse lighting layout is one of the most important factors affecting visibility, safety, productivity, and energy efficiency. Simply selecting a high-quality LED fixture is not enough. Fixture placement, mounting height, beam distribution, spacing, and foot candle requirements all influence overall lighting performance.
Whether you’re designing a new warehouse, upgrading an existing facility, or planning a distribution center retrofit, a professional warehouse lighting layout helps ensure the right amount of light reaches every area of the building.
What Is a Warehouse Lighting Layout?
A warehouse lighting layout is a photometric plan that determines:
- Fixture locations
- Fixture spacing
- Mounting heights
- Light levels
- Uniformity ratios
- Energy consumption
- Lighting performance throughout the facility
The objective is to provide adequate illumination while minimizing energy use and fixture quantities.
A warehouse lighting layout is often created using photometric software that simulates how light will perform within a facility before installation.

Why Warehouse Lighting Layouts Matter
Poor lighting layouts can create:
- Dark spots
- Excessive shadows
- Poor rack visibility
- Unsafe forklift conditions
- Inventory picking errors
- Higher operating costs
Proper lighting design helps improve:
- Employee productivity
- Safety
- Inventory accuracy
- Operational efficiency
- Energy performance
Information Required for a Lighting Layout
Several pieces of information are needed before designing a warehouse lighting system.
Facility Dimensions
Including:
- Length
- Width
- Ceiling height
Storage Rack Information
Including:
- Rack height
- Rack orientation
- Aisle widths

Facility Operations
Examples include:
- Storage only
- Distribution center
- Fulfillment center
- Manufacturing support
- Cold storage
Target Light Levels
Required foot candle levels vary depending on facility operations.
Typical Warehouse Foot Candle Requirements
Recommended Light Levels
| Area | Recommended Foot Candles |
|---|---|
| General Storage | 10-20 FC |
| Warehouse Aisles | 15-30 FC |
| Distribution Operations | 20-40 FC |
| Packing Areas | 30-50 FC |
| Inspection Areas | 50-100 FC |
| Loading Docks | 20-30 FC |
Higher foot candle levels generally improve visibility but also increase energy consumption if not designed efficiently.
Key Warehouse Lighting Design Factors
Mounting Height
Ceiling height significantly impacts fixture selection.
| Ceiling Height | Typical Fixture Type |
|---|---|
| 15-20 Feet | Low Bay Fixtures |
| 20-30 Feet | UFO High Bays |
| 30-40 Feet | High Output High Bays |
| 40-60 Feet | Linear High Bays |
| 60+ Feet | Specialty High Mast Fixtures |
Fixture Distribution
The beam pattern affects:
- Coverage area
- Uniformity
- Rack visibility
- Fixture quantity
Fixture Spacing
Proper spacing helps avoid:
- Dark zones
- Excessive overlap
- Wasted energy

Factors That Influence Warehouse Lighting Layouts
| Design Factor | Impact on Layout |
|---|---|
| Ceiling Height | Fixture Selection |
| Rack Height | Vertical Illumination |
| Aisle Width | Fixture Distribution Pattern |
| Foot Candle Target | Fixture Count |
| Facility Operations | Lighting Requirements |
| Uniformity Goals | Fixture Placement |

Understanding Lighting Uniformity
Average foot candle levels only tell part of the story.
Uniformity measures how evenly light is distributed throughout the facility.
Benefits of improved uniformity include:
- Reduced shadows
- Better visibility
- Improved worker comfort
- Safer forklift operation
- More consistent lighting conditions
Many warehouse lighting projects focus on achieving both adequate foot candles and acceptable uniformity ratios.
Open Warehouse vs Rack Storage Layouts
Open Warehouse Areas
Open storage facilities often allow:
- Wider fixture spacing
- Broader beam patterns
- Fewer fixture restrictions
High Rack Warehouses
Rack-oriented facilities often require:
- Greater vertical illumination
- Narrower distribution patterns
- Aisle-focused fixture placement
Warehouse layouts should always consider how storage systems impact light distribution.
Photometric Lighting Plans
A photometric plan provides a visual representation of lighting performance before installation.
Photometric reports typically show:
- Fixture locations
- Average foot candles
- Minimum foot candles
- Maximum foot candles
- Uniformity ratios
- Light distribution patterns
This allows facility managers to evaluate performance before purchasing equipment.
Common Warehouse Lighting Design Mistakes
Choosing Fixtures Before Creating a Layout
Fixture selection should support the lighting design, not dictate it.
Ignoring Rack Height
Tall storage systems often require specialized lighting layouts.
Focusing Only on Fixture Wattage
Higher wattage does not automatically create better lighting.
Overlooking Uniformity
Dark spots and excessive brightness variations can negatively impact safety and productivity.
LED Controls and Layout Planning
Lighting controls should be considered during the design phase.
Popular options include:
- Motion Sensors
- Occupancy Sensors
- Daylight Harvesting
- Zoned Controls
- Smart Lighting Systems
These technologies can further reduce operating costs while maintaining adequate illumination.

Frequently Asked Questions
What is a warehouse lighting layout?
A warehouse lighting layout is a photometric design that determines fixture placement, spacing, and expected lighting performance.
Why is a photometric plan important?
Photometric plans verify foot candle levels, uniformity, and fixture performance before installation.
How many foot candles should a warehouse have?
Most warehouses operate between 10 and 40 foot candles depending on the application.
Does rack height affect lighting design?
Yes. Taller storage systems require greater emphasis on vertical illumination and fixture placement.
Can lighting controls reduce energy use?
Yes. Motion sensors and occupancy controls often generate substantial additional energy savings.
