Warehouse Lighting & Power Upgrade Planning Guide

Plan a warehouse lighting upgrade around how your team uses the building: aisles, packing stations, loading docks and equipment power needs. Start with a fixture inventory and problem-area walkthrough, then compare lighting layouts, controls, electrical work and installation access.

1. Assess the lighting your warehouse needs

Repeated lamp failures, dark rack faces, glare at packing stations and uneven dock lighting are reasons to review the system. A lighting assessment should consider both current conditions and planned changes to racking, pick modules or production equipment.

• Fixture inventory: count fixtures by zone and identify their input wattage, condition and mounting height.
• Work areas: record where people read labels, scan products, pack orders or inspect parts.
• Light readings: ask for measurements and a proposed layout that considers rack shadows, uniformity and glare.
• Controls: discuss occupancy sensors, daylight response and zones that need continuous light.

There is no single brightness target for every warehouse task. Ask the project team to explain the proposed light levels for your actual work areas, rather than selecting replacement fixtures by wattage alone.

2. Compare energy use and the full project cost

A useful proposal separates fixture and control costs, electrical work, lifts, installation labor and any required documentation. Compare operating costs using your fixture inventory, hours and utility rate.

This example assumes the same fixture count and operating hours: watts x fixture count x hours / 1,000 = kWh. The $20,000 annual difference excludes installation costs, demand charges, maintenance, incentives and control changes. It does not establish suitable brightness or predict your facility's savings. Use total fixture input power, including any ballast, and your actual rate when comparing proposals.

3. Coordinate lighting with equipment power upgrades

Tell your contractor about new machinery, forklift chargers, conveyor changes or additional work areas before the lighting scope is finalized. Lighting replacements and new equipment connections may need different circuits, controls or panel work.

• Provide existing panel schedules and equipment specifications when available.
• Identify proposed equipment voltage, location and connection requirements.
• Ask which existing circuits can serve the proposed layout and which need changes.
• Include shutdown coordination and applicable permits or energy-code documentation in the scope.

A lower lighting load does not, by itself, confirm that a panel or circuit can supply new equipment. Have a qualified electrical contractor assess the installation. PRS provides industrial electrical services, including panel work, lighting and equipment power connections.

4. Plan access, installation and handoff

Review lift routes, rack access, active forklift lanes and areas that cannot close. Agree on installation zones and work windows before the crew arrives, including any shutdowns that need your maintenance team.

• Before work: confirm fixture locations, control zones, access and site contacts.
• During installation: coordinate work areas and electrical isolation with the facility team.
• At handoff: review light coverage, sensor operation, settings, fixture information and maintenance needs.

If dock equipment or warehouse layout changes are part of the project, review warehouse equipment services alongside the lighting plan.
