The most important things in brief

For a lighting renovation, AKA-Leuchten AG handles the analysis, planning and coordination of the project phases, if desired also in conjunction with the electrician. For the customer this means a clearly guided all-in-one package instead of individual, loosely coordinated steps. Often the right solution is found faster than expected because existing stock, products and procurement are considered together.

What we repeatedly notice in practice: the greatest uncertainty is rarely in the technology, but in the process. That is why clean lighting planning in a renovation project is so important, especially when the existing stock is to be kept in use.

Who is a lighting planning appropriate for in the renovation?

The solution mainly fits B2B customers with older installations where, for example, track systems are still intact, but suitable light sources are no longer available or no longer permissible. Also in buildings with historic preservation or when existing luminaires must remain for other reasons, a renovation makes sense. AKA-Leuchten AG works for public institutions, industry and commerce where consulting, planning and implementation are desired from a single source.

When renovation is sensible and when not

Contrary to common belief, renovation is not automatically the cheapest solution. If the basic installation is too old, AKA-Leuchten AG will say so openly and also recommends a new system if that is more economical in the end.

How does the lighting renovation proceed step by step?

The process is clearly divided into phases. This makes it possible for the customer to understand what happens when and who performs the next step.

  1. Initial contact and first clarification typically take 1 to 3 days.
  2. On-site needs assessment usually takes 1 to 2 weeks.
  3. Internal meeting with lighting planning, production and AVOR takes 1 to 2 weeks.
  4. The proposal is prepared in about 1 week.
  5. Sample delivery and distribution take 1 to 3 weeks.
  6. The sample installation usually takes 2 to 3 weeks.
  7. Approval, order placement and delivery take manufacturer-dependent about 2 to 8 weeks.
  8. Installation, acceptance and invoicing normally take 2 to 6 weeks.
I calculate the project and will gladly convince you of our solution.

What do consulting and lighting consulting cost?

The discussion, on-site intake and preparation of the offer are not charged. An additional lighting planning or a lighting concept usually costs less than CHF 800.00. This makes the entry affordable before anything is ordered or produced.

The main cost driver is not the first meeting but the depth of the project solution. When samples, product adjustments or manufacturer-dependent procurement are added, the effort accordingly shifts.

What alternatives are conceivable in the project?

A renovation often preserves more than one initially thinks. In a reference project with an industrial hall and a warehouse on two floors, the existing track remained intact even though T8 fluorescent tubes were no longer available. Thus the solution could build on the stock and still switch to modern technology.

VariantWhen it fitsTypical effect
Renovation with existing stockWhen track or luminaires can be reusedLess intrusion into the substance
Complete replacementWhen the old system no longer fits technically or economicallyMore planning and reconstruction effort
Phased implementationWhen operation must continueBetter controllable project day-to-day
Typical options in project comparison

The installation is carried out by the customer's responsible electrician, not by AKA-Leuchten AG themselves. On request, AKA-Leuchten AG can coordinate between customer and electrician so that the implementation does not get stuck in coordination matters.

Where are the limits of renovation?

The limits are where the stock itself becomes a problem. If the basic installation, the track or the economic framework conditions are too weak, a restart may be more sensible than a retrofit.

This is a point that many first misjudge: not every renovation is automatically the better solution. In projects with difficult old installations, a new system can cost less than adapting the old structure.

What does a concrete project look like?

In the concrete reference project it was an industrial hall or warehouse with two floors and a room height of about 3.5 m. For a partial area, a free lighting breakdown was created upon request, and there was also a reordering of emergency lights. After on-site visit, sampling and approval, delivery could be made within a week.

For readers who want to grasp the process: exactly such projects show why we at AKA-Leuchten AG rely on project-specific and manufacturer-independent consulting. We can work from different procurement channels and tailor the solution so that it is technically and economically suitable.

Frequently asked questions

Do I have to organize the installation myself?
Yes, the installation runs via the customer’s responsible electrician. On request, AKA-Leuchten AG can take care of coordinating between customer and electrician so that the implementation fits together smoothly.
How quickly is delivery possible?
For standard warehouse goods delivery can be within a week. For approved projects, the duration depends on the manufacturer, typically 2 to 8 weeks is realistic.
What if the project shows that renovation does not make sense?
Then AKA-Leuchten AG will tell you openly. In such cases a new system can be more economical than a retrofit, and this is communicated transparently to the customer.
Can renovation be implemented in stages?
Yes, that is possible. Especially with ongoing operation, a gradual approach is often more practical because interventions can be planned better.

For decision-makers, the most important point at the end is not the luminaire itself but planning security. This is exactly what good lighting planning provides, because it brings stock, procurement and implementation together.

If you are looking for renovation with clear responsibility, AKA-Leuchten AG is a direct contact. From the initial meeting to delivery, the process remains understandable and the boundaries of a solution are openly discussed.
