From requirement definition to commissioning of a new industrial warehouse lighting installation, and the decisions that matter most.
In a new installation constraints are fewer and decisions weigh more: geometry, optics selection and control architecture are fixed once. 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. This methodological scenario reconstructs the typical design path of a new industrial warehouse lighting installation.
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.
The first decision concerns the performance level to be achieved and the standard it derives from. This is where both over-sizing — paid for over the whole installation life in energy and maintenance — and under-sizing, which surfaces at commissioning, are avoided. The requirement must be written with its reference condition: value, calculation surface or plane, and point in the installation life.
In a new installation geometry is a design variable, not a constraint: spacings, heights and aiming can be optimised together with the photometric distribution. Optics must be selected on real geometry, not on typical layouts. Generic distributions applied to particular geometries produce insufficient uniformity even when average values are met.
The approach that gives the best results in industrial warehouse lighting combines zoning by visual task with differentiated requirements per department and optics chosen for mounting height and structural pitch, assessing alternatives on annual consumption rather than installed power.
The control architecture must be decided at design stage, not added later: wiring, addressing and protocols affect conduits and switchboards. Choosing open protocols preserves freedom of action in later years and avoids being tied to a single supplier for every change.
Commissioning closes the path: agreed protocol, measurement points defined on plan, declared instrumentation, written tolerances. The same information is needed, years later, to check whether the installation is still within requirements.
The difficulties that most often emerge in industrial warehouse lighting projects are not about product selection, but about defining requirements and verifying results.
An orderly method drastically reduces variations during works and disputes at commissioning. Three choices make the difference from the earliest stages.
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.
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.

It depends on the visual task: EN 12464-1 differentiates storage, assembly lines and quality control, with increasing illuminance, UGR and colour rendering requirements.
Only if the existing grid meets uniformity requirements: LED often allows fewer points, but this must be confirmed by calculation.
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.
