Yes, in most cases a factory can simply continue operating during the installation of new LED lighting. Whether that is also wise and safe depends on the environment, the type of installation, and how well the planning has been prepared. The questions below provide operations managers and technical supervisors with a clear framework to make that assessment.
What determines whether an installation can be done without a production shutdown?
Every hall is different, and that makes the answer to this question always situational. The height of the installation, the presence of hazardous substances or processes, the accessibility of the luminaires, and the extent to which the work area can be physically separated from the active production environment all play a role. The better that separation can be achieved, the greater the likelihood that installation during production is responsible.
Specifically, the following elements play a role:
- Working height: High-altitude installations require scaffolding or aerial platforms that take up space on the work floor. That is not always compatible with ongoing processes.
- Environment type: In environments with dust, heat, chemicals, or explosion hazards, additional safety requirements apply to work during production.
- Electrical infrastructure: If the existing cabling needs to be replaced, temporary power outages are inevitable. These must be carefully planned.
- Staff attendance: Work above active workplaces requires barriers, safety protocols, and clear communication with the shop floor.
By industrial lighting projects In harsh environments, preparation is at least as important as the installation itself. A thorough preliminary site scan largely determines whether a phased approach is feasible.
Installation methods that minimize workplace downtime
Off-site prefabrication, combined with rapid swap or click systems on location, is the most effective way to minimize disruption. As a result, the actual installation time per luminaire is minimal, which greatly reduces inconvenience to the workplace.
Other proven methods are:
- Phased replacement by zone: Tackling one section of the hall at a time, while the rest of production continues.
- Night shift or weekend installations: Planning work during hours when production is stopped or running at a lower level.
- Use of existing mounting points: New LED luminaires that fit the existing suspension system, eliminating the need to drill new holes or build new structures.
- Mobile lighting as a temporary solution: Deploy temporary construction lighting in areas where the permanent lighting temporarily fails.
The risks of installation during active production
Falling material, unexpected power outages, insufficient lighting in transition zones, and an increased risk of accidents because installers and production personnel share the same space: those are the primary risks. They are manageable, but do require a structured approach.
Employee safety: Falling tools or luminaire components pose a direct danger to employees on the work floor. Shields, safety cages, and clear demarcations are not an option but a necessity.
Continuity of processes: Machines that depend on a stable power supply can be disrupted if the electrical engineering work is not precisely coordinated with the production process. Consultation with the process manager is essential in this regard.
Certification and liability: In environments subject to ATEX regulations or other strict standards, additional restrictions apply to work performed during operation. Complying with this is not only a safety issue, but also a legal obligation.
How does a phased LED installation project work in practice?
Typically, there are four steps: a technical survey, phasing based on the production rhythm, execution per zone, and a final delivery including light measurement. Experience shows that coordination with operations takes up the most lead time, not the installation itself.
A typical project workflow looks like this:
- Technical recording and lighting design: Measuring the space, cataloging existing infrastructure, and drawing up a lighting plan that meets the specific requirements of the environment.
- Aligning phasing with the production calendar: Determine together with the operations manager which zones are available and when, taking into account maintenance stops, shift schedules, and seasonal production fluctuations.
- Execution per zone: Installation of the luminaires per demarcated section, with temporary bridging lighting where necessary. After each phase, the zone is handed over and production can resume.
- Delivery and light measurement: Upon completion of all phases, a final measurement is carried out to verify whether the lighting levels comply with the applicable standards and the agreed specifications.
When is a complete production shutdown still the wisest choice?
Sometimes one concentrated shutdown is cheaper than weeks of phased disruption. A full production shutdown is preferable when the installation requires major electrotechnical adjustments, when the environment is too dangerous for combined activities, or when a phased approach entails significantly more costs or risks.
Situations where a planned stop is preferred:
- Complete replacement of the main electrical distribution or cabling infrastructure
- Installations in ATEX zones or environments with aggressive chemical exposure
- Halls with a very high occupancy rate where cordoning off work zones is practically unfeasible
- Projects where the total installation time in a phased approach would span several months
in the heavy industry Companies regularly and consciously choose an annual maintenance shutdown as the ideal time to completely renew their lighting infrastructure. That combines efficiency with safety.
What does an operations manager need to arrange before the installation begins?
Good preparation prevents surprises during execution. Think of an up-to-date site map, an overview of critical processes and machines, clear agreements on available time windows, and an internal communication plan directed at shift workers and safety officers.
In practical terms, this means:
- Location documentation in order: Provide the installer with up-to-date drawings of the hall, cabling, and existing lighting infrastructure.
- Mapping process risks: Determine which machines or processes must absolutely not be disrupted and record this in the project plan.
- Reserving time slots: In consultation with planning and production, schedule concrete time slots for work per zone.
- Establish safety protocol: Draft a work permit and safety protocol, in collaboration with the HSE manager, that applies to the entire installation period.
- Managing internal communication: Inform shift supervisors, machine operators, and safety personnel in a timely manner about scheduling, closures, and emergency procedures.
The more information is available in advance, the more efficiently the installer can work and the less disruption the workplace will experience. Also consider the financial side: in certain cases, LED upgrades are eligible for the Energy investment tax credit, which strengthens the business case for a thorough approach.
Practical example: DFDS Vlaardingen
DFDS modernised its terminal in Vlaardingen: the existing section was made more sustainable while a new terminal section was being built at the same time, on a terminal that operates 24/7. Commissioned by main contractor Boskalis, JEL provided the lighting design and installation of the new terminal lighting: 34 lighting masts of 30 metres with around 180 DarkLicht luminaires in total. The installation with aerial work platform and crane was planned so that operations could continue. The site achieves an average of 50 lux with a uniformity of up to 0.45.
A terminal is not a factory hall, but the question is the same: how can lighting be replaced without bringing work to a standstill? The answer lies largely in the preparation. When lighting design, masts, electrical installation and ongoing operations are aligned in advance, the work can adapt to the rhythm of the site rather than the other way round.
For a production environment, this comes down to three choices: letting the sequence of work be determined by where and when people are working, scheduling the required equipment in advance, and having one party coordinate between design, installation and the shop floor.
