We manufacture, supply, and install industrial LED lighting for environments where standard fixtures cannot survive. Semi-finished products arrive in Nijkerk, and the final product and all our custom work leave from there.

An installation that works at the time and place it needs to, even when conditions are unfavorable. That requires three things that we control ourselves: a calculation whose assumptions are on the table, a luminaire that fits the environment rather than the budget, and parts that will still be there in ten years.
We want to be the party that can deliver on that in the toughest environments, and nothing more than that. Where it is not possible, we say so in advance and refer elsewhere, even if it costs us the assignment.
The standard lines arrive as semi-finished products: housings, optics, light modules, and drivers. We assemble, configure, and test them here, and the custom work we carry out ourselves. This means delivery times, custom designs, and repairability after ten years are not just promises, but a natural result of where the work stands.
Housings, optics, light modules, and drivers from DCbright and DarkLicht arrive in Nijkerk as semi-finished products. We are the exclusive distributor of these products for the industrial markets in which we operate, and we are also the company that assembles them into the final product.

Role

Build-to-order, configured per order. Beam angle, light color, cable entry, bracket, and voltage are determined only during assembly, not at the time of purchase. As a result, there is no need to keep finished product inventory in all variants.

We carry out custom light colors, custom CRI, custom optics, and custom designs ourselves. For Farm Frites, we similarly built a food-grade version with borosilicate glass, because the standard version could not withstand the combination of heat and cleaning routine.

Each luminaire is tested before shipment. For projects with a lighting calculation, we record the orientation per luminaire so that no searching is required on-site and the measured situation matches the calculated one.

We keep drivers, LED modules, and front panels in stock, even for products outside the warranty period and for product lines that were delivered years ago. Those who assemble their own fixtures can open them up instead of replacing them. The Barracuda has been supported continuously since 2013.

Because the final assembly takes place here, there is no need to wait for a production slot abroad. Customization is available upon consultation.
A deviating light color or CRI is a configuration choice, not a special project with a minimum order quantity.
Anyone who assembles themselves keeps parts in stock and can open a fixture instead of replacing it. That is the rationale behind the same promise on the homepage.
We deliver standard items within a week. Custom work, such as a different light color, a different CRI, or a custom design, is available upon consultation. Parts and service are handled through installation and maintenance, the full program is on products.
We are not an online store. Everything goes through a lighting inquiry and a quote.
We do not have ATEX certification yet. For hazardous areas, we are not the right party at the moment, and we state that in advance.
We do not deliver to consumers or for residential interiors.

With us, a lighting question does not start with a part number, but with the situation: mounting height, accessibility, temperature, vibrations, corrosion class, the standard being tested against, and the environment that must not receive light. From this follows a lighting calculation, and from that follows the luminaire.
We supply the assumptions: the calculation grid, the maintenance factor, the applied standardization and the values at the sensitive points in the area. You can use that to compare our calculation with that of someone else.
Seven components that we execute ourselves, from initial calculation to post-completion inspection.

An earlier LED installation with sports floodlights did not perform in the port. We designed a new solution with tightly aimed DarkLicht luminaires on thirty new mast structures. Better beam control put more usable light on the yard at a fraction of the consumption.

Lucas de Graaf will become vice chair of the Outdoor Core Team of NSVV, the Dutch Foundation for Lighting Science. The core team is developing guidelines for outdoor lighting. The challenges we face in the industry—from heat and corrosion to light pollution around a terminal—can thus be addressed in the guidelines against which the entire sector evaluates its practices.

Do you have a technical background or a background in international business, and are you looking for a place where you experience a lighting inquiry from initial conversation to delivery? Then this is that place. You will work in Nijkerk, right next to the assembly line, and you will deal with projects in over fifty countries.
No nailed-down job description: tell us what you can do and where you want to go, and we'll see if it's a match.
We work internationally on industrial lighting projects while remaining locally connected to Nijkerk and the surrounding area. From this commitment, we support seven associations and initiatives. We mention them because it is part of being a family business, not as an argument to work with us.
