We have compiled some important information about our LED lights here. You are welcome to contact us for any questions or to get an offer for our LED luminaires.

LEDs consist of crystals and generate much less heat than filament bulbs when they shine. As a result, LEDs can be operated with a significantly lower power consumption. In comparative calculations with light bulbs and halogen spotlights, savings in electricity costs of up to 70% are possible in various cases. And all with the same lumen efficiency or brightness.

The long lifetime of the LED is also very persuasive. With filament bulbs and halogen spotlights, the service life is approximately 2,000 4,000 hours, with energy saving bulbs, it is up to 6,000 15,000 hours. LEDs, on the other hand, have a service life of more than 50,000 hours. The luminaires produced by LED2WORK even achieve a lifetime of 60,000 hours of operation or more.

Since LEDs emit no harmful UV or infrared rays and are operated completely without mercury or other dangerous toxins, they are also more environmentally friendly and present no health risk.

LED2WORK GmbH develops and produces all the luminaires itself. Starting with the thermal management of the basic element, to the respective IP protection class to the installed electronics, all the steps are performed inside LED2WORK, or by established, long-standing partners in Germany.

Housing parts are supplied predominantly from the Baden-Württemberg region, ensuring us and our customers a fast and reliable supply. The incorporated LED technology comes mainly from Seoul Semiconductor (SSC). SSC is one of the world’s leading LED manufacturers, its corporate headquarters are in Seoul, South Korea. The LEDs are purchased and assembled as complete modules according to our specifications in Germany. The LEDs used by LED2WORK are characterised by a very narrow binning (almost no variations in the colour temperatures and brightness values), a high Ra value (at least > 80), as well as excellent efficiency (at least > 90Lumen/Watt).

LEDs for industry

Industry requires very high quality, economical and reliable lighting, in order for production to be economically viable. In addition to the above requirements, LEDs are also almost maintenance-free. With a service life of 60,000 hours and extremely high reliability, LED2WORK provides a high savings potential on maintenance-related costs. The industry profits twice: in addition to the cost factor for electricity, the costs for maintenance are also greatly reduced.

Photobiological safety according to DIN EN 62471

All of the LEDs used by LED2WORK GmbH do not pose any photobiological hazard in terms of the criteria required in DIN 62471. Due to their classification in risk group 0 (zero), no labelling is required.

LEDs – The lighting of the future

A LED (light emitting diode) is a semiconductor component which consists of crystals, such as Silicon, among other things. It is a semiconductor because the material incorporated in the diode only conducts current at certain temperatures, or only in certain directions. The semiconductor component in the LED consists of two electrodes (anode and cathode) and several layers of semiconducting material. The layers of the LED are oppositely charged. This means that one layer has a surplus and the other layer has a shortage of electrons. The electrons in the layer with the excess are activated to glide into the layer with the opposite charge by the flow of current. They give off energy when the electrons transfer over into the oppositely charged layer. This is made visible in the form of light.

A LED works with direct current. This means that the LED is only illuminated when the anode has a higher voltage than the cathode. In order for the LED to be illuminated continuously, it is operated with direct current (current whose intensity and direction does not change over time). Since the electricity grids worldwide are most frequently operated with alternating current for economic and technical reasons (current, which changes its direction (polarity) in regular repetition, for example, in the form of a sine wave), LEDs require certain devices. Therefore, LEDs are delivered with appropriate resistors or with a DC device, which converts the alternating current..

The ermergence of colored LED light

LEDs light up in different colors. The color of the light depends on the used semiconductor material. Depending on the material, a certain band width or wavelength is produced, which is responsible for the light color. Thus, for example, red light is created with a lower power, blue light with a higher energy. Depending on the composition, LEDs glow in red, green, yellow or blue. As a result, each individual LED is limited to a certain wavelength. In this respect, white LED light, which consists of many wavelengths, must be created artificially. This is done by applying a layer of phosphorus over blue LEDs. The blue light is then converted into white light through the yellow phosphorus. Alternatively, red, green and blue LEDs are mixed. Since LEDs are already produced in sizes of less than a millimetre, this mixture can be created easily.

Light quality

White light is a combination of a whole range of light colours. The higher the blue component is, the colder the light effect. The light colour of a luminaire is described in Kelvin, or by its colour temperature. Here there are three groups: warm white? < 3,300 Kelvin, neutral white 3,300 to 5,300 Kelvin and daylight white > 5,300 Kelvin. The higher the Kelvin value, the higher the light efficiency. Since good vision in the workplace and in the production is needed, a daylight white light should be selected there. However, the “blue tinge” in the light is stronger as the value increases. The difference over the brightness of the traditional filament bulb becomes immense from 6,500 Kelvin upwards. Now the question arises, whether this is still comfortable for the user. LED2WORK offers luminaires with various Kelvin values, from 4,000 Kelvin to the most frequently used light value of 5,500 Kelvin, which corresponds to the daylight white, depending on the requirements.

At system workstations and on machinery, correct colour perception is also extremely important. Thus the light from LEDs with the same light colour can have a different spectral light composition and therefore have different colour rendering. With the quality of the colour rendering, the more colours that are used to mix the spectrum of an LED luminaire, the more accurate the colour rendering. The colour rendering index Ra is used here to specify the colour rendering quality. The maximum value here is a Ra value of 100 – if this is the case, all the colours appear identical with the reference light source. LED2WORK luminaires have a Ra value between 80 and 93, which is an extremely high value in the marketplace.


LEDs generate heat. But, considerably less heat than traditional illuminants. This low generation of heat means there is less of an impact, not just on the LED itself but on the complete lamp module. The heat that is still produced is diverted by sophisticated heat dissipation in the LED modules. This factor, combined with the LED technology, means that LEDs by LED2WORK can be operated for even more than 60,000 hours.

LED lights used in industrial environments require special resilience. Confronted by special ambient conditions such as heat, oil, flying metal chips or coolants, LED2WORK has developed LED lights, which are especially adapted to these conditions. This includes, for example, covers with borosilicate glass/ESG glass, which is especially resistant to chemicals and temperature, depending on the requirement. The Viton? seals in the luminaires also protect against oil and the luminaires are offered in various types, right up to the highest protection classes.

LED lights for use in machinery and plant engineering must fulfil special requirements. Therefore, it is possible to connect luminaires by LED2WORK to the machine voltage via a sensor connector or to the mains via an AC connector. Signal lamps even have a connection to the PLC control system.
