Best LED Lights for Warehouses and Industrial Spaces in 2026

Poor lighting in a warehouse costs more than the electricity bill. Dim aisles slow pick rates, increase errors, and create safety risks that add up fast. Getting warehouse LED lighting right is one of the highest-ROI operational decisions a facility can make. The two fixtures that dominate this space are the UFO high bay and the linear high bay. Knowing which one fits your space, and why, is where every good warehouse lighting decision starts.

Nothing But LEDs helps buyers across the US find the right fixture for their warehouse or industrial application. This guide covers what to look for, how UFO and linear high bays compare, how many lumens you actually need, the best picks available, and how to install cleanly. Everything in one place.

What to Look for in Warehouse LED Lighting

Not every LED fixture is built for a warehouse environment. Industrial spaces have demands that standard commercial lighting cannot meet: high ceilings, wide areas, dust, vibration, and in some cases moisture or chemical exposure. Here are the specs that actually matter when choosing warehouse LED lighting.

Lumen Output

Lumens determine how much light the fixture produces. For warehouses, you need enough lumens to hit the required foot-candle level at floor height after accounting for the distance the light travels. A fixture rated at 20,000 lumens at 15 feet delivers very different floor illuminance than the same fixture at 30 feet. Always calculate for your actual ceiling height, not just the fixture's rated output.

Wattage and Efficacy

Higher wattage produces more light, but efficacy (lumens per watt) determines how efficiently it does so. Look for fixtures rated at 130 lm/W or above for quality commercial warehouse use. A 150W fixture at 140 lm/W outperforms a 200W fixture at 90 lm/W in both output and energy cost.

IP Rating

For clean, dry warehouse interiors, IP65 is standard. For environments with dust, moisture, or wash-down areas, IP66 is the stronger choice. For food production or refrigerated facilities, confirm the fixture's rated temperature range and moisture resistance before ordering.

CCT and CRI

5000K is the standard colour temperature for warehouse and industrial lighting. It produces a crisp, bright white that maximises visual clarity for picking, packing, and inspection tasks. CRI 80 is the baseline for most warehouse applications. CRI 90 is worth considering for quality control areas where colour accuracy matters.

UFO High Bay vs Linear High Bay for Warehouses

This is the core decision for most warehouse lighting upgrades. Both are high-output fixtures designed for ceilings of 15 feet and above. Both are available from Nothing But LEDs. But they distribute light differently and suit different warehouse configurations.

Feature	UFO High Bay	Linear High Bay
Shape	Round, compact disc profile	Long rectangular bar
Light distribution	360-degree downward spread	Wide linear spread along the row
Best layout	Open plan, no racking	Aisle-based racking systems
Ceiling height	15 to 40+ ft	15 to 30 ft typical
Mounting	Hook or chain mount	Surface, chain, or V-hook mount
Linkable	No	Yes, can be linked end to end
Wattage range	100W to 300W+	40W to 200W+

When to Choose a UFO High Bay

A UFO high bay is the right choice for open-plan warehouse floors where the ceiling is clear and fixtures can be spaced evenly across the space. The circular design distributes light in all directions below the fixture, making it ideal for areas without fixed racking or shelving that would create shadows. Distribution centres, manufacturing floors, and large open storage areas are the natural home of the UFO high bay.

When to Choose a Linear High Bay

A linear high bay is built for aisle-based layouts. The rectangular form factor directs light along the length of the aisle, which suits racking systems where product is stored on shelves and workers need to see both the floor and shelf labels clearly. Linear high bays can also be linked end to end to create a continuous run of light above each aisle, the cleanest and most uniform approach for a racked warehouse.

Top Picks: Best Warehouse LED Lights

These are the fixtures from Nothing But LEDs that consistently perform across the most common warehouse and industrial applications. Every product is available with full spec documentation.

1. 100W UFO High Bay, Mid-Size Warehouses and Distribution

A 100W UFO high bay delivering 13,000 to 14,000 lumens is the starting point for most mid-size warehouse applications with 20 to 25 foot ceilings. Clean, reliable, and efficient at around 130 to 140 lm/W. IP65 rated for dry warehouse environments. Available at the Nothing But LEDs UFO High Bay collection.

2. 200W UFO High Bay, Large Open Warehouses and Manufacturing

For ceiling heights of 25 to 35 feet or larger open-plan spaces, a 200W UFO high bay delivers 26,000 to 28,000 lumens with the output to reach floor level effectively from height. A strong choice for manufacturing floors, large distribution centres, and any open-plan space where a single fixture needs to cover a wide area.

3. 80W Linear High Bay, Aisle and Racking Applications

An 80W linear high bay at around 10,000 to 11,000 lumens is a clean match for standard warehouse racking aisles at 15 to 20 foot ceiling heights. Linkable end to end for continuous aisle coverage. Available at the Nothing But LEDs Linear High Bay collection.

4. 150W Linear High Bay, Higher Rack Systems and Cold Storage

Where racking goes higher or ceiling clearance is greater, a 150W linear high bay delivers the output to keep aisle illumination consistent from top shelf to floor. Rated for a wide operating temperature range, making it suitable for refrigerated warehouse environments with the right IP rating.

How Many Lumens for a Warehouse?

Warehouse lumens per square foot is not a single fixed number. It depends on ceiling height, the tasks being performed, and the foot-candle standard you are targeting. Here is a practical reference.

Application	Target Foot-Candles	Approx Lumens per Sq Ft	Fixture Recommendation
General storage	10 to 20 fc	10 to 20 lm/sq ft	100W UFO or 80W linear
Active pick and pack	20 to 30 fc	20 to 30 lm/sq ft	150W UFO or 100W linear
Fine detail or inspection	50 fc+	50+ lm/sq ft	200W UFO or 150W linear
Loading docks	20 to 30 fc	20 to 30 lm/sq ft	100W to 150W UFO

These are starting points. Ceiling height changes the calculation significantly. The same fixture at 15 feet delivers roughly four times the foot-candles at floor level compared to 30 feet. For any large or complex space, request a photometric layout before finalising fixture count. It is the only accurate way to confirm actual foot-candle distribution.

OSHA recommends a minimum illuminance of 5 foot-candles for general warehouse areas and 30 foot-candles for warehouse tasks involving more detailed work such as packing and inspection. Many facilities operating below these levels do not realise it until a photometric survey confirms the gap.

Installation Tips

Getting the fixture right is half the job. Installation determines whether that fixture actually performs the way it should. These are the most important things to get right on a warehouse LED upgrade.

• Space fixtures correctly. For UFO high bays, spacing should not exceed 1 to 1.5 times the mounting height. At 20 feet, space fixtures no more than 20 to 30 feet apart.
• Use a photometric layout for large spaces. Estimating fixture count by guesswork almost always results in either over-lighting or under-lighting zones.
• Add occupancy sensors where practical. Sensor controls can reduce warehouse lighting energy use by 30 to 50% beyond the base LED saving, particularly effective in areas with variable occupancy like storage zones and loading docks.
• Check your power supply voltage before ordering. Most commercial warehouse fixtures run on 120V to 277V and are compatible with standard US commercial supply, but confirm before the order.
• Plan linkable run length before installation. For aisle applications with linear high bays, each driver has a maximum wattage. Stay below 80% of rated capacity for reliability.
• Label any ballast bypass installations clearly for future maintenance personnel.

FAQ

What is the best wattage for warehouse high bay lighting?

It depends on the ceiling height. For 15 to 20 foot ceilings, 80W to 100W fixtures are usually enough. 20 to 30 foot ceilings typically need 150W to 200W, while ceilings above 30 feet often require 200W to 300W. Always calculate warehouse lumens per square foot based on your actual space.

Can I replace metal halide fixtures directly with LED high bays?

Yes. UFO high bay and linear high bay fixtures are direct replacements for metal halide and HPS systems. A 100W LED high bay can often replace a 250W to 400W metal halide fixture while using 60 to 70% less energy.

How long do warehouse LED high bay lights last?

Quality warehouse LED lighting fixtures are rated for 50,000 hours at L70. At 16 hours per day, that is more than 8 years of operation. They also last much longer than metal halide fixtures and require far less maintenance.

Do I need a photometric report for a warehouse lighting upgrade?

For small warehouses, a basic lumen calculation is usually enough. For spaces over 5,000 square feet, high ceilings, or racking systems, a photometric report is strongly recommended. It shows actual light distribution and helps prevent dark areas after installation.

Conclusion

Getting warehouse LED lighting right means matching the fixture to the space. UFO high bays for open-plan layouts. Linear high bays for aisle-based racking. The right lumen output for the ceiling height. The right IP rating for the environment. And a sensor strategy that makes the energy savings compound after the LED switch.
