Industrial LED lighting retrofit

An industrial LED lighting retrofit replaces or reorganises an existing hall-lighting system. The design starts with an audit of fixtures, circuits, positions and measured problems before comparing new layouts.

  • Industrial lighting retrofit layout based on geometry and the required result, not wattage alone
  • Optics and output aligned with mounting height, aisles and visual tasks
  • Explicit assumptions for existing fixtures, circuits, measured problems and reusable mounting points
  • A direct connection between calculation, suitable product series, evidence and quote

Where this solution fits

Start by confirming the site types that belong on this path and the cases that need a different solution.

Good fit for
  • High-bay LED replacement programmes
  • Mercury, metal-halide or fluorescent upgrades
  • Control and zoning modernisation
  • Retrofits that reuse part of the mounting grid
Use another route when
  • Projects that assume one-for-one replacement without current geometry or performance evidence
  • Sites with unsafe or undocumented electrical infrastructure awaiting specialist assessment
  • New-build halls where no reuse constraint exists

Industrial indoor lighting

What the project should achieve

A useful specification balances visual performance, reliability, operating cost and the realities of installation.

01

Useful light

The distribution supports improving maintained visibility and control without carrying old layout failures into the new system instead of maximising lumens outside the area that matters.

02

Controlled glare

Position, optics and aiming account for users and existing workstations, changed output levels and reused mounting positions.

03

Predictable operation

Controls, environmental conditions and maintenance access are part of selection rather than an afterthought after pricing.

04

A verifiable specification

The result connects targets, visible assumptions, the proposed variant and evidence the project team can check.

Design criteria

These are the decisions that shape fixture selection, photometric work and the final quote assumptions.

Design criteriaDesign approach
Existing inventoryRecord model, quantity, power, optic, age, failures, mounting and circuit grouping for the current installation.
Baseline evidenceUse measurements, operator feedback, energy data and known dark or glare zones to define the problem being solved.
Reuse constraintsCheck brackets, cabling, distribution boards, controls and structural points before assuming they remain suitable.
Replacement strategyCompare one-for-one, changed spacing and zoned redesign against performance, downtime and installation cost.
Commissioning planPreserve assumptions for aiming, sensor settings, scene tests and post-installation verification.

Design criteria

Selection guide

Use these comparisons to narrow the system direction before choosing an individual model.

Start with geometry
Dimensions and mounting positions determine the useful distribution before wattage is considered.
Use maintained targets
Design for the required maintained result and declared maintenance assumptions, not initial lumens alone.
Compare the distribution
A lower-power fixture with the right optic can be more useful than a higher-output fixture with poor placement.
Check the environment
Temperature, dust, moisture, impacts, corrosion and electrical conditions can change the suitable series.
Keep assumptions visible
Any missing drawing, target or operating condition should remain explicit until the project team confirms it.
Existing industrial ceiling and work area with old fixtures, circuits or mounting points clearly documented; use an honest survey image, not a fabricated before-and-after.

Design criteria

Standards and verification notes

Applicable targets depend on the country, site and project class. Final compliance must be checked against the current project brief and calculation.

Workplace targets

Set maintained illuminance, uniformity and glare targets from the actual task and the applicable EN 12464-1 project requirements.

Electrical and product evidence

Confirm the declaration, safety documentation and requested photometric files for the exact proposed model and market.

Site conditions

Check temperature, dust, moisture, impacts and cleaning regime before fixing IP, IK and housing requirements.

Inputs for the first calculation
Send the geometry and operating context first. Product wattage is an output of the selection process, not the starting assumption.
  • Drawing or dimensions for the industrial lighting retrofit
  • Mounting points and heights, plus existing fixtures, circuits, measured problems and reusable mounting points
  • Required maintained criteria, project class or description of the current problem
  • Operating hours, control approach and relevant environmental conditions
  • Planned quantity, delivery country and required document list
Project deliverables
The fastest route to a useful first response is a short, application-specific project brief.
  • A documented luminaire, optic and control direction
  • Calculation assumptions and information gaps for confirmation
  • Fixture quantities and layout basis for commercial review
  • List of datasheets, photometric files and certificates required for the quote
