Two certifications by an independent body, two normative frameworks that our calculations comply with, and DarkSky compliance for light-sensitive locations. Below is an explanation of each quality mark: what it is, who assesses it, and what tangible benefits it offers you.
A lighting calculation is not an exact science as long as no uniform calculation method is followed. Two suppliers can present a different result using the same luminaires without either of them lying. Therefore, we conform to the NSVV code of conduct: this makes the plans mutually comparable and allows you to put the offers side by side.
Both certificates are direct downloads, without a form. For specifications or a tender, we can supply them with an accompanying statement upon request.
Not every quality mark is a certificate. Two are independently tested and verifiable, two are normative frameworks that we follow, and one is DarkSky, which is incorporated into both the product and the design. That distinction is stated explicitly here because it determines what you can do with it in a specification.
| Quality mark | Type | Tested by | What's in it for you |
|---|---|---|---|
| ISO 9001 | Certificate | EBN Certification | admission requirement in specifications, demonstrable with a certificate |
| Veterinary Clinical Assistant | Certificate | EBN Certification | access to sites and independent project leadership |
| NSVV code of conduct | Signed code | NSVV and NLA | offers become comparable to each other |
| NEN-EN and CIE | regulatory framework | NEN and CIE | EN 12464-1 and -2, EN 12193, CIE 150, NEN 1010 and 1891 |
| Dark Sky | Product and design | DarkSky International | DS1 compliance plus calculation on the sensitive points |
What we do not have: there is no ATEX or IECEx certification and no class approval from a classification society such as DNV or Lloyd’s. If your specifications require that, we state this in advance; that is cheaper for both parties than halfway through a process.
Choose a quality mark; the explanation, the certifying body, and the significance for your project will appear below it.
| Tested by | EBN Certification |
| Applies to | the entire organization |
| Demonstrable with | EBN.ISO.QMS.4454 |
ISO 9001 is the international standard for quality management. It is not about the product, but about the organization behind it: how a request is evaluated, how a deviation is recorded, how a complaint leads to an improvement, and how all of that remains repeatable when someone else is at the table.
The certification was awarded by EBN Certification under number EBN.ISO.QMS.4454, and is periodically reassessed. That latter point is key: it is not a one-time statement but a continuous audit.
In specifications or a tender, ISO 9001 is often an admission requirement. The certificate is available for direct download here; for a submission, we can provide it with an accompanying statement upon request.

| Tested by | EBN Certification |
| Applies to | on-site work |
| Demonstrable with | EBN.VCA.4454 |
VCA stands for Safety, Health and Environment Checklist Contractors. The two stars mean that we have not only been assessed as an executing party, but also on the independent management of larger projects with subcontractors and multiple parties at a single location.
The certificate number is EBN.VCA.4454. For you, this means: preliminary risk assessment, workplace inspections during execution, certified employees, and incident registration. On a terminal, a construction site, or a factory site, this is usually a strict requirement just to be allowed on the premises.
We can perform or supervise installation and commissioning ourselves, including work at height and in operational areas. The certificate is a direct download.

| Tested by | NSVV and NLA |
| Applies to | every lighting calculation |
| Demonstrable with | calculation with parameters |
There is no legally prescribed calculation method for a lighting plan. Maintenance factor, calculation grid, reflection values, and measurement plane are freely selectable, and each of those choices shifts the outcome. As a result, two suppliers can show vastly different results using the same luminaire without either of them being untruthful.
The Code of Conduct for Lighting Calculations, developed by the Dutch Foundation for Illumination Engineering together with the Netherlands Lighting Association, records those choices. We have signed it and consistently base our calculations on it.
You will receive the calculation along with the applied parameters, so you can compare it with an offer from another provider. The calculation itself is free of charge.

| Tested by | NEN and CIE |
| Applies to | the lighting design |
| Demonstrable with | standard and class in the plan |
Our lighting designs are tested against the standard that applies to the situation. For outdoors this is NEN-EN 12464-2, indoors NEN-EN 12464-1, and for sports lighting NEN-EN 12193. For light nuisance we adhere to CIE 150, and for the electrical installation NEN 1010 and NEN 1891. Each of these standards prescribes how much light is required, how evenly distributed it must be, and how much glare is acceptable.
That is not a formality. If an installation deviates from the standard and an accident occurs, the question regarding the design's justification is the first one asked. We therefore record in the lighting plan which standard, which class, and which values have been maintained.
The lighting plan states which standard and which class have been applied, with the calculated values alongside them: NEN-EN 12464-2 for outdoors, 12464-1 for indoors, 12193 for sports, CIE 150 for light nuisance, and NEN 1010 and 1891 for the installation. This enables you to demonstrate that the installation complies.

| Tested by | DarkSky International |
| Applies to | noise-sensitive locations |
| Demonstrable with | DS1 report upon request |
Light pollution affects local residents, traffic, and wildlife, and is increasingly becoming a factor in permit requirements. Where this is an issue, we recommend full-cut-off fixtures that do not emit light above a specified angle, such as the DarkLicht and DCbright series.
This goes two ways here. In terms of product technology, the luminaires comply with DS1, the strictest category in the DarkSky system; the underlying report is available upon request. In addition, we apply the principle in the design itself, by choosing the light distribution in such a way that nothing extends above the cut-off.
You will receive two items: the DS1 report for the light fixture upon request, and a calculation that takes into account not only the operational zone but also sensitive areas in the surrounding area: residences, roads, and nature reserves. That combination is what you need when applying for a permit or addressing a complaint.

There is no legally prescribed calculation method for a lighting design. Maintenance factor, calculation grid, reflection values, and measurement plane are all four freely selectable, and each of those choices shifts the outcome. Thus, two providers using the same luminaire can show a difference of dozens of percents without anything in it being false.
The NSVV code of conduct establishes those choices. As a result, our calculation can be compared with that of another signatory, allowing you to compare offers side by side rather than choosing based on good faith.
| Maintenance factor | recorded and stated in the plan |
| Calculation grid | in accordance with the code of conduct |
| Reflection values | named per surface |
| Contact surface and height | explicitly in the report |
| What maintenance factor was used, and what is it based on? |
| On which measurement plane and at what height were the values calculated? |
| Which grid was used, and what is its resolution? |
| What reflection values were assumed for the surroundings? |
| Which standard and which class were applied for this situation? |
If you do not get a clear answer to these five questions, the plan is not comparable. That is no detail: it determines whether the installation will do what was promised after delivery.
In heavy industry, construction, and the maritime sector, ISO 9001 and VCA** are often entry requirements rather than a bonus. These clients work with us because we meet those requirements and because the lighting calculation is correct.
We illuminate environments where every detail counts: industrial sites, cranes, machinery, and ships. In these settings, lighting isn’t a design choice but a safety measure—and it must be demonstrably effective. Our partnership with DCbright keeps us up to date on the latest technical developments in these sectors.
What we do not do in the process is use a quality mark as a sales argument for something it does not cover. ISO 9001 says something about our processes, VCA** about working safely on location, the NSVV code of conduct about the calculation method. None of the three says anything about the lifespan of a luminaire; for that we refer to quality and warranty.
A certificate has been assessed by an independent body and has a number and a period of validity; ISO 9001 and VCA** are examples of this. A set of standards such as NEN-EN or CIE is a set of rules according to which we design, without an external party checking this per project. DarkSky is in between: in terms of product technology, the luminaires comply with DS1, with a report available upon request, and in addition we apply the principle in the design. This page indicates which type each quality mark is.
Because without a uniform calculation method, a fair comparison is not possible. Maintenance factor, calculation grid, and reflection values strongly determine the outcome. An offer with an optimistic maintenance factor looks better on paper and delivers less light in practice. The code of conduct establishes those choices, ensuring you compare apples with apples.
Nothing. We perform the calculation in accordance with the NSVV code of conduct and provide the parameters used, so that you can verify it against another offer. There is no obligation attached.
No. JEL Products does not have ATEX or IECEx certification, and our fixtures are not intended for use in potentially explosive atmospheres. If your installation requires such certification, we will inform you of this in advance and refer you to a specialized provider, even if that means we lose the contract.
No. There is no type approval from a classification society. If your client or classification society asks for this, please let us know when submitting your request: we will then provide the supporting documentation that is available, such as certification, test reports, and material specifications, and we will also state where that support ends.
Yes, in terms of product specifications, the luminaires comply with DS1, the strictest category in the DarkSky system; the corresponding report is available upon request. In addition, we apply the principle in the design: above the set cut-off, the light emission is zero, and we demonstrate this in the calculation, including the values at sensitive points in the surrounding area.
For outdoor workplaces NEN-EN 12464-2 and for indoor workplaces NEN-EN 12464-1; for sports lighting NEN-EN 12193. For light pollution we adhere to CIE 150, and for the electrical installation NEN 1010 and NEN 1891. Which standard and which class have been applied in your situation are stated with the calculated values in the lighting plan, so that you can check and discuss this.
Yes. Both certificates are available for direct download on this page. For a registration, we can provide them with an accompanying statement upon request, supplemented with insurance details and references where necessary.
That we were not only assessed as an executing party, but also on independently managing larger projects with subcontractors. For a client, this means that we can manage a project on-site, including the surrounding safety organization.
ISO 9001 and VCA** are audited by EBN Certification, an independent certification body, with periodic re-inspections. The certificate numbers are EBN.ISO.QMS.4454 and EBN.VCA.4454. The NSVV code of conduct is a signed declaration submitted to the Dutch Foundation for Illumination (Nederlandse Stichting Voor Verlichtingskunde); this is not audited per project, but it is traceable within the calculation itself.
No, and that is an important distinction. ISO 9001 is about our processes, VCA** about working safely on site, and the code of conduct about the calculation method. For product quality, lifespan, and warranty, we refer to the quality and warranty page, which lists the terms per product line and the conditions.
We will say that right away. Sometimes there is an alternative that the client accepts, such as a test report or a declaration instead of a certification; sometimes another supplier is the right choice. Submit the requirement with your request, and you will know where you stand within one business day.
Provide the dimensions, mounting height, and available positions. You will receive a calculation in accordance with the NSVV code of conduct, including the applied maintenance factor, calculation grid, and reflection values, so that you can compare it with another offer. That costs you nothing.
Your request is being reviewed by an engineer. We will respond within 1 business day.
