Choosing the right industrial LED high bay lighting can significantly impact your facility’s efficiency and safety. At PacLights, we understand the challenges businesses face when selecting lighting solutions for large, high-ceiling spaces.
This guide will walk you through the essential factors to consider, from lumen output to beam angle, ensuring you make an informed decision for your industrial lighting needs.
What Are Industrial LED High Bay Lights?
Defining High Bay Lighting for Industry
Industrial LED high bay lights are robust lighting solutions engineered for spacious areas with elevated ceilings. These fixtures illuminate warehouses, manufacturing plants, and distribution centers where ceiling heights typically range from 20 to 45 feet.
LED Technology: A Game-Changer for Industrial Lighting
LED technology has transformed industrial illumination. Compared to traditional metal halide or fluorescent lights, LEDs use up to 75% less energy while delivering superior brightness. This reduction translates to substantial cost savings for businesses. A U.S. Department of Energy study revealed that industrial facilities can save an average of $0.25 per square foot annually by transitioning to LED lighting.

LEDs also boast a significantly longer lifespan (often exceeding 50,000 hours). This longevity results in less frequent replacements and lower maintenance costs. The Illuminating Engineering Society reports that LED fixtures can last up to five times longer than conventional lighting options.
Key Features to Look for in High Bay Fixtures
When selecting high bay fixtures, consider these essential features:
- Lumen Output: This measures the total light emitted by the fixture. For industrial spaces, fixtures that provide at least 100 lumens per watt offer optimal efficiency.
- Color Temperature: This affects the light’s appearance and can influence worker productivity. The Lighting Research Center suggests cooler temperatures (5000K-6500K) for task-oriented areas, while warmer temperatures (2700K-3000K) suit break rooms or areas requiring a more relaxed atmosphere.
- Beam Angle: This determines the light’s spread. For uniform illumination in large spaces, fixtures with beam angles between 120 and 140 degrees work best.
- IP Rating: This indicates the fixture’s resistance to dust and moisture. In industrial settings, fixtures with an IP65 rating (or higher) ensure durability and longevity.
- Dimming Capabilities: Fixtures with dimming options allow light level adjustments based on natural light or occupancy, further increasing energy savings.
These factors form the foundation for selecting effective high bay lighting. However, the process doesn’t end here. The next crucial step involves calculating the right number of fixtures for your specific space. This calculation ensures optimal illumination and energy efficiency throughout your facility.
Key Factors in High Bay Lighting Selection

Lumen Output and Efficacy
The brightness of your lighting solution depends on lumen output. Industrial spaces require fixtures that deliver at least 18,000 lumens for optimal visibility. Efficacy, measured in lumens per watt, indicates how efficiently a fixture converts electricity into light. Select fixtures with an efficacy of at least 130 lumens per watt to ensure energy efficiency.
A DesignLights Consortium study found that high-efficiency LED high bays can achieve efficacies of up to 160 lumens per watt, potentially reducing energy consumption by 60% compared to traditional metal halide fixtures.
Color Quality Considerations
Color temperature affects the perceived warmth or coolness of light. Industrial settings often prefer cooler temperatures between 4000K and 5000K to promote alertness and visibility. However, the right choice depends on your specific application.
The Color Rendering Index (CRI) measures how accurately a light source reveals colors compared to natural daylight. Try to select fixtures with a CRI of 80 or higher for most industrial applications. Higher CRI values (90+) become essential in areas where color accuracy is critical (e.g., quality control stations).
Light Distribution and Beam Angle
Beam angle determines how light spreads across your space. Wide beam angles (120-140 degrees) provide more uniform illumination over large areas, while narrower beams can highlight specific work zones or aisles.
Your facility’s layout should guide your beam angle selection. Open warehouses benefit from wider angles, while spaces with high shelving or machinery might require a combination of wide and narrow beam angles for optimal coverage.
Durability and Environmental Protection
Industrial environments often expose lighting fixtures to harsh conditions. The Ingress Protection (IP) rating indicates a fixture’s resistance to elements like dust and moisture. Most industrial applications require fixtures with an IP65 rating or higher, ensuring protection against dust and low-pressure water jets from any direction.
Particularly challenging environments, such as food processing facilities or outdoor installations, may need fixtures with even higher IP ratings (IP66 or IP67) for maximum durability.
Smart Controls for Enhanced Efficiency
Smart controls can significantly boost your lighting system’s efficiency. Dimming capabilities allow light level adjustments based on natural light or occupancy, potentially increasing energy savings by an additional 20-30% according to the U.S. Department of Energy.
Look for fixtures compatible with advanced control systems that offer features such as:
- Occupancy sensing
- Daylight harvesting
- Scheduling
- Remote monitoring and management
These features not only save energy but also provide valuable data for optimizing your facility’s operations.
The careful consideration of these factors will equip you to choose high bay lighting that enhances productivity, safety, and energy efficiency in your industrial space. Now that you understand the key elements of high bay lighting, let’s explore how to calculate the right number of fixtures for your specific facility layout.
How to Calculate the Right Number of High Bay Fixtures

Determine Your Space’s Lighting Requirements
The first step in calculating the correct number of high bay fixtures involves assessing your space’s lighting needs. The Illuminating Engineering Society (IES) provides guidelines for various industrial applications. General warehouse areas typically require 10-20 foot-candles (fc), while detailed assembly areas may need 50-100 fc. Consult the IES Lighting Handbook for specific recommendations based on your industry and tasks performed.
Measure your facility’s dimensions accurately. Include the length, width, and ceiling height of the area you plan to illuminate. These measurements are essential for calculating the total square footage and determining the optimal mounting height for your fixtures.
Use Lighting Calculation Tools
While manual calculations are possible, lighting calculation software streamlines the process and improves accuracy. Many manufacturers offer free online calculators or lighting layout services. These tools consider factors such as room dimensions, reflectance values of surfaces, and desired light levels to recommend the appropriate number and placement of fixtures.
For a quick estimate, you can use this formula:
Number of Fixtures = (Desired Foot-Candles × Room Area) ÷ (Lumens per Fixture × Light Loss Factor)
The Light Loss Factor (LLF) accounts for depreciation over time and typically ranges between 0.7 and 0.8 for LED fixtures.
Optimize Fixture Placement
Mounting height and spacing play a critical role in achieving uniform illumination. As a general rule, the distance between fixtures should be 1 to 1.5 times the mounting height. For example, if your fixtures are mounted at 30 feet, try to space them 30-45 feet apart.
This rule may need adjustment based on your specific layout and obstacles (like shelving or machinery). Use lighting design software to create a photometric layout, which visually represents light distribution and helps identify potential dark spots or areas of overlighting.
Proper spacing ensures even illumination and maximizes energy efficiency. Overlighting wastes energy and can create glare, while underlighting compromises safety and productivity.
Consider Advanced Control Systems
Incorporating advanced control systems can further optimize your lighting setup. These systems (which include occupancy sensors, daylight harvesting, and scheduling capabilities) can reduce energy consumption by an additional 20-30% (according to the U.S. Department of Energy).
When selecting fixtures, look for options compatible with these control systems. This compatibility allows for future upgrades and ensures your lighting solution remains efficient as technology advances.
