What are the recommended light levels for a warehouse?

IESNA (Illuminating Engineering Society) guidelines suggest 20-30 foot-candles for general warehouse storage and 50-75 foot-candles for picking and packing areas. Loading docks typically need 30-50 foot-candles. We design to these standards and can adjust based on the tasks performed in each zone.

Commercial warehouse LED lighting upgrades replace metal halide, HPS, and fluorescent fixtures with high-efficiency LED high-bays and linear strips engineered for tall-ceiling storage, pick-and-pack stations, and loading docks. Most warehouse projects cut lighting energy use 50 to 70 percent, qualify for Michigan utility rebates, and pay back in 2 to 3 years.

Warehouse LED Lighting by Zone

Warehouses have distinct zones with different lighting requirements. We design each area properly rather than applying a one-size-fits-all approach.

High Bay Storage Areas

Rack storage aisles with ceiling heights of 20-40+ feet require UFO high-bay or linear high-bay LED fixtures. We calculate foot-candle targets based on your racking system and SKU density, then spec fixtures for uniform coverage with no dark spots.

Typical fixtures: 150W-240W UFO high-bay LEDs replacing 400W-1000W metal halide

Pick-and-Pack Stations

Accurate order fulfillment requires higher light levels and better color rendering than bulk storage. We spec brighter, higher-CRI fixtures for these task-critical areas to reduce picking errors and improve worker comfort during long shifts.

Typical fixtures: Linear LED shop lights or low-bay troffers, 80+ CRI

Loading Docks

Dock areas need bright, durable lighting that handles the abuse of daily truck traffic, forklift activity, and temperature swings. We use LED dock lights and wall packs rated for wet and cold locations where appropriate.

Typical fixtures: LED wall packs, dock lights, and canopy lights

Office and Break Areas

Warehouse office and break room areas typically still run T8 or T12 fluorescent troffers. LED panel retrofits improve light quality and cut energy use in these occupied spaces, often with the shortest payback in the whole facility.

Typical fixtures: 2x4 LED flat panels or LED troffer retrofits

Freezer and Cold Storage

Standard LED fixtures are not rated for sub-zero environments. We spec cold storage-rated LEDs that operate reliably down to -40°F and provide immediate full output the moment they're switched on, unlike fluorescents that flicker and dim in cold.

Typical fixtures: Cold-rated LED high-bays with vapor-tight or sealed housings

Exterior and Security

Parking lots, truck courts, and perimeter areas benefit from LED area lights and wall packs that provide consistent, high-quality illumination for driver safety and facility security. Motion sensors available for after-hours energy savings.

Typical fixtures: LED shoebox area lights, wall packs, floodlights

The Real Cost of Running Metal Halide

Most warehouses that haven't upgraded are still running metal halide or high-pressure sodium fixtures. Here's what that's actually costing you every year.

A 400W metal halide draws ~458W total with ballast losses
A 150W LED replacement draws exactly 150W with the same or better output
That's 308 watts saved per fixture, per hour of operation
At 6,000 hours per year (16 hr/day), that's 1,848 kWh saved per fixture
At $0.12/kWh, that's $222 saved per fixture, per year
A 100-fixture warehouse saves $22,200+ annually in electricity alone
Add reduced maintenance costs for lamp replacements and it's even more

Add-Ons That Accelerate Your ROI

📡

Occupancy Sensors

Aisle-by-aisle motion sensors dim or shut off lights in inactive rack zones. In facilities with varying shift schedules and partial utilization, occupancy sensors can add another 20-30% in energy savings on top of the LED upgrade itself.

☀️

Daylight Harvesting

Facilities with skylights or clerestory windows can use daylight sensors to automatically dim LED fixtures when natural light is sufficient. Reduces energy consumption without any impact on productivity.

📊

Utility Rebates

Michigan utilities including Consumers Energy and DTE Energy offer substantial rebates on commercial LED lighting upgrades. We identify and apply for rebates on your behalf, which can cut the project cost by 20-40% in eligible cases.

Warehouse Lighting FAQs

A 150W to 200W LED high-bay typically replaces a 400W metal halide. The exact replacement depends on the fixture's efficacy (lumens per watt) and your target foot-candle levels. Modern LED high-bays achieve 130-160+ lumens per watt, meaning a 150W LED often provides more usable light than the original 400W fixture.

LED high-bay fixtures are commonly mounted at heights from 15 to 50 feet. Above 40 feet, a narrow-beam optic (60-90 degree) concentrates light more effectively and may require fewer fixtures for the same coverage. We'll calculate the optimal mounting height and beam angle for your specific layout.

In most cases, yes. LED high-bays typically replace existing fixtures using the existing conduit and wiring runs. Bypassing the ballast is required for direct LED replacements. A licensed electrician will assess any wiring modifications needed during the site assessment at no charge.
