Reference project: how we set up a industrial warehouse lighting intervention
The working method applied by the Lumeitalia technical office to a industrial warehouse lighting intervention, stage by stage.

Overview
This piece describes a design method, not a specific site: the values given are setup criteria, not measurements from a built installation. In production halls, light affects work quality, safety and fixed costs: it is one of the few measures with a measurable payback on the energy bill. The aim is to make repeatable the sequence of decisions that takes a industrial warehouse lighting intervention from survey to commissioning.
Applicable standards
The regulatory reference for industrial warehouse lighting is not a single document but a coordinated set of standards covering performance, safety and environmental impact. In design practice the following documents drive the main choices.
EN 12464-1 — lighting of indoor work places.
Italian Legislative Decree 81/2008 — workplace safety and lighting requirements.
EN 1838 — emergency lighting.
Stage 1 — Survey of the existing condition
The survey precedes any solution hypothesis. Real geometry, position and height of existing luminaires, condition of poles and lines, installed power, operating hours and issues reported by the operator are all recorded. The photographic survey documents the initial state and is the basis for the before/after comparison.
In industrial warehouse lighting contexts the survey must include the conditions that constrain the solution: matching levels to the real visual tasks of each production area and access limitations for future maintenance.
Stage 2 — Requirements and calculation assumptions
Requirements are declared in writing with their reference standard and the rationale for the chosen category. The same note fixes the maintenance factor, the assumed cleaning cycle and the ambient conditions considered. This is the document that makes the design verifiable and that, in a dispute, separates an execution error from a requirement never agreed.
Stage 3 — Solution selection
Selection starts from the photometric distribution suited to the surveyed geometry, then considers environmental compatibility, the control system and maintainability. At least two alternative configurations are assessed with their impact on luminaire count, installed power and maintenance burden: a documented comparison is what makes the final choice defensible.
Stage 4 — Verification and handover
On-site verification follows the protocol agreed in the specification and closes with a report comparing measured values against declared requirements. At handover the updated calculation report, photometric files of the installed luminaires, maintenance plan and control system configuration are transferred. Without this package, later operation starts from scratch.
Performance data from a real intervention can only be shared if measured and authorised by the client: for this reason the method is described here without site figures. Project-specific documentation is available on request from the technical office.
Recurring critical points
The difficulties that most often emerge in industrial warehouse lighting projects are not about product selection, but about defining requirements and verifying results.
Matching levels to the real visual tasks of each production area.
Handling high ceilings and racking that create shadows.
Integrating daylight without compromising uniformity.
Design approach
An orderly method drastically reduces variations during works and disputes at commissioning. Three choices make the difference from the earliest stages.
Zoning by visual task with differentiated requirements per department.
Optics chosen for mounting height and structural pitch.
Daylight harvesting on perimeter bays and skylights.
Parameters to verify
Maintained illuminance — EN 12464-1 — per department visual task
UGR — EN 12464-1 — glare limit per workstation
Colour rendering — EN 12464-1 — minimum required for the task
Emergency lighting — EN 1838 — escape routes and critical points
Most frequent mistakes
Non-conformities found at commissioning almost always come from three causes: requirements not declared or declared without a reference standard, calculation run on idealised geometry, and an optimistic maintenance factor. All three can be avoided at zero cost during design.
Geometric, electrical and photographic survey of the existing condition
Requirements declared in writing with reference standard
Maintenance factor and cleaning cycle made explicit
At least two alternative configurations documented
A industrial warehouse lighting project holds up over time when requirements are declared, the calculation reproduces real conditions and on-site verification follows an agreed protocol. Component selection matters, but comes later: without measurable requirements even the best product delivers a result that cannot be demonstrated. Centro Studi Lumeitalia makes its technical office available to review requirements and design checks.

Domande frequenti
How much light does a warehouse need?+
It depends on the visual task: EN 12464-1 differentiates storage, assembly lines and quality control, with increasing illuminance, UGR and colour rendering requirements.
Should existing light points be reused in a retrofit?+
Only if the existing grid meets uniformity requirements: LED often allows fewer points, but this must be confirmed by calculation.
Where should a industrial warehouse lighting project start?+
From a written definition of performance requirements and verification conditions: this step drives every later choice and makes the result either disputable or defensible at commissioning.
Which documents should be requested from the supplier?+
Photometric files of the proposed luminaires, declaration of conformity, lifetime data declared per IES LM-80 with its conditions, the maintenance schedule and warranty terms.
