Warehouse Lighting: How to Build a Useful Project Brief

Key takeaways

• Separate storage, travel, picking, packing, and loading areas in your brief.
• Record dimensions and mounting heights instead of relying only on floor area.
• Use a shared checklist to compare proposed layouts and equipment.

A warehouse can contain several different lighting tasks within one building. A useful project brief makes those differences visible before anyone proposes fixture quantities. The following worksheet is a practical way to organize your discussion with a lighting professional or supplier.

Map the work, not just the building

Start with a simple plan that labels storage aisles, open staging areas, packing benches, pedestrian routes, and loading areas. Mark where staff need to read labels, inspect products, or work around moving equipment. Note areas with complaints about shadows or glare without assuming that adding more fixtures is the answer.

Collect dimensions and existing equipment details

Record the building dimensions, the proposed fixture mounting height, and obstructions such as beams or services. Add photographs and a list of existing fixture models where readable. Have the supply and existing controls identified by a qualified person; do not infer electrical compatibility from the appearance of the old light.

Keep unknown items marked “to confirm.” A clearly identified gap is more useful than a guessed number that later becomes a purchasing assumption. If a section of the warehouse will change next quarter, include both the current and planned arrangement.

Describe when each area is used

For each zone, note normal operating hours, shift changes, and periods of intermittent use. Record the controls currently installed and the behavior you want—for example, separately managed zones rather than one building-wide setting. DOE’s LED Basics explains that LEDs can be integrated with occupancy and daylight-responsive controls; the actual equipment combination still needs verification.

Review a proposal against your brief

Ask the proposer to identify the fixture model, mounting positions, optics, and control assumptions. Where a photometric layout is supplied, check that the room dimensions and rack arrangement match your brief. Ask a qualified lighting professional to establish the appropriate task criteria for your application; a general warehouse article cannot supply a universal spacing or fixture-count rule.

For a phased installation, agree on how the first completed area will be assessed before ordering the remaining phases. Record any changes to the brief so that later deliveries use the intended model and accessories.

Common questions

Can floor area alone determine quantity?

It is useful context, but your brief should also include height, tasks, obstructions, and layout. A square-footage number leaves too many purchasing assumptions unresolved.

What should I send first?

A marked floor plan, dimensions, photos, known fixture details, and your operating schedule are a useful starting package.
