Our LED portfolio.





For everyone who knows what they want.

Quick, simple, specific – find the machine light that suits your needs. Now with a simple filter function.


This is what distinguishes us as a manufacturer of LED industrial luminaires.

Top quality

We produce our LED industrial luminaires at our facility in Bielefeld. CE specifications and EMC tests are a matter of course for us. As a manufacturer, we carry out heat and cold tests, mechanical tests and IP and surge tests ourselves. So that you have maximum security in terms of functionality, stability and durability.

Personal consultation

Industrial luminaires for optimum machine lighting or optimum lighting at the assembly station are not changed on a whim. That is clear to everyone. Replacement or modernisation requires structural issues to be sorted out. But other adjustments are also frequently on the agenda. For this, we advise you personally – from the first inquiry to the installation. This will allow your work processes to run smoothly.

Flexible collaboration

We deliver top quality and simultaneously have a wide product range. We do not dread any comparison with our competition. Our consultation also provides you a good price. Many requirements can be met in different ways. Many variations are possible in terms of material and cooperation. We will determine your specific needs and can definitely reach an agreement.


LED customised solutions.

Due to the increasing complexity and the individuality of today’s machines, signaling and lighting are taking up an ever-increasing role of serving as an integrated design component and as a means of optimizing specific processes through the visualization of information.

Though our offerings extensive, standard product do not always fulfill all your mechanical, photometric and interface requirements; therefore, a customized product is sometimes the only possible solution. Why are we the right partner in these cases?

Because of our extensive experience and exposure to the vast projects we have undertaken with our clients to ensure their individual requirements were met with customized and unique solutions, and thanks to the success of these specialized projects, we can now share this experience with you to help you achieve a custom solution quicker and more cost effectively.

Frequently asked questions.

The protection class of industrial luminaires is based on the IP classification. This is also referred to as the IP protection class. We offer all common protection classes and can also produce special designs if required. We will be happy to advise you personally. The common IP protection classes for which we receive queries are LED industrial luminaires with IP44, IP54, IP68 and IP69K.

Our 24V LED industrial luminaires have protection class III and are therefore only supplied with protective extra-low voltage. The supply voltage is thus so low that there is no danger from it. In addition to protection class III, there are also protection classes II for “protective insulation” and protection class I for “protective conductors”.

LED luminaires with 24V supply voltage are the rule. But 230V LED industrial luminaires are also used. The advantage with 230V: the luminaire has additional power supply. If there is a power failure, the light is still functional.

Two covers are frequently requested: a plastic cover (PMMA) and tempered glass. The type of cover also depends on the place of use. Fire safety in particular plays a role here.

The term LED industrial luminaire refers to the entire luminaire with all its components. The LED industrial lamp is the illuminant, i.e. the respective lamp that is used. However, the two terms are also sometimes used as synonyms.


Three advantages of LED technology for industrial luminaires.


We guarantee a service life of 60,000 hours for our LED luminaires. The service life is considered to have expired as soon as the light intensity drops below 70 percent. The luminaire therefore does not fail immediately, but the luminous intensity decreases. In 3-shift operation over five days per week, we thus guarantee a luminosity of over 70 % for 9.6 years. As a rule, the luminaires thus outlive the system in which they are installed.

Colour fidelity plays an essential role for a clear view at the point of use. The first question here is whether white or multi-coloured (RGBW luminaires) illumination is required. Colour fidelity is a major advantage of LEDs. Our LED luminaires have good colour rendering, i.e. Ra >80 or CRI >80. The wavelength is in the range between 400nm and 800nm.



LEDs provide a uniform and flicker-free light. This puts less strain on the eyes. You become fatigued much more slowly. The beam angle is 120 degrees unless otherwise specified. The luminosity is generated via many small LEDs and not just via a single light source. This way, there are far fewer shadows, for example from the hand when performing a work step. This results in fewer errors during the workday.

Wind Energy

We`ve got the hang of it.


Renewable energy production is becoming increasingly important, especially wind turbines. With a hub height of 60 meters and 1.5 megawatts of power, wind turbines that were originally considered to be enormous are now standard and built worldwide using German technology. In order for the turbines to work perfectly as well as cost-effectively, the optimum balance between torque and speed must be found. For this, it is necessary to be able to adjust the rotor blades. It’s not enough to turn the head of the turbine into or out of the wind. In case of high wind speeds, rotor blade adjustment is an additional way to apply the brakes effectively and an important safety aspect.


All three rotor blades must always be aligned synchronously, because excessive forces can otherwise act on a single blade. This means the rotor blade adjustment must have a central control system that is also guaranteed to function even in case of power failure. To make the task even more difficult, the hub is only accessible from the outside. On the shaft of the rotor, only a few contacts are available on the slip ring for establishing a connection. A control system via the hub and accommodation of rotor blade technology in the nacelle are therefore not possible. On-site installation in the hub is not practical and economical due to the height and difficult accessibility.


The entire rotor blade adjustment system is supplied with electrical power just through the slip rings, so only a few contacts of the slip ring are necessary. A central control box coordinates the rotor blade positions, which are each adjusted by their own drive control. This includes a battery pack to maintain control capability in case of power failure. Everything is modular and ready to plug in. All connections are pre-tested on a specially designed test station with contact force monitoring, eliminating errors and ensuring fast commissioning.

The central control module connects the individual drive controls with a single connector kit in each case. These align the rotor blade with a servomotor. The pre-fabricated installation can be quickly incorporated into the hub on the ground. Supply, signals and bus are consolidated in a single robust plug connector. The rotor blade is completely installed electrically in no time.
