Our mission – Intelligence in Light As one of the first companies, we began to design and manufacture highly specialised LED luminaires for machine and industrial applications. Nowadays we are one of the leading companies in this sector and work with innovative ideas to supplement light with meaningful added value or to make targeted use of the possibilities of its properties. Our promise to you: Improving existing lighting solutions – brighter, more durable, more economical Higher productivity thanks to perfectly coordinated lighting We call this added value: "Intelligence in Light".

Better through experience Good light is not more expensive than poorer light, only better and more economical. It is always the better ideas, the engineering and the skilful implementation that make good lighting. This is why we demand and promote innovative thinking and value-oriented work in our company - across the entire workforce.

Service life Light and LED technology LED luminaires from LED2WORK are developed as durable products. The service life of the luminaire and the installed electronics is at least 50,000 operating hours (high-power LED technology) or at least 60,000 operating hours (mid-power LED technology). As soon as the luminous intensity drops below 70 %, the service life of the LED is considered fulfilled. However, this does not mean that the luminaire fails immediately, but a further reduction in luminous flux below 70 % of the original value can be expected. Examples: This information is based on 250 work...

External influences on service life Compared to conventional light sources, a total failure of LED chips is extremely rare. They are practically maintenance-free after installation. Only the brightness, i.e. the luminous flux, decreases slightly over the service life. Internal and external factors influence the service life of the LED. External influences chemical influences moisture electrical influences chemical influences mechanical influences Thermal management electrical influences High-quality housings made of specially alloyed aluminium serve as housing and heat sinks for the built-in...

Colour Rendering Index Ra The higher the colour rendering index, the more faithful the colour rendering. The Ra value for the representation of the colour rendering index (CRI) is an indicator for the colour rendering of light sources. This value describes how the colour rendering of an artificial light source is compared to the colour rendering in sunlight. The higher the Ra value, the better the colour rendering of the light source. The colour rendering index can reach Ra values of up to 100, which corresponds to absolutely lifelike colour rendering (sunlight, black body radiation). Colour...

Real lumen Real lumen is the actual measured brightness of the entire luminaire. Lumen is the basic unit of luminous flux. Manufacturers of incandescent lamps, fluorescent tubes or LED chips usually specify the value of the total luminous flux of the light source in the technical data sheets. This clearly defines the luminous flux (lumens) to be expected. Due to the laboratory measurement procedures of the light manufacturers, the lumen values stated in the data sheets are not reached in reality. In addition, any other material in the path of the light emitted (diffusers, covers, glass panes)...

The quality of each LED chip is due to the narrow binning. In the industrial production process of LED chips, there are also small deviations within individual batches and thus small differences between the individual LED chips. The colour temperature (Kelvin), the colour and luminous flux (lumens), and the required forward voltage drop, differ from each other within a production batch. As a result, LED chips that are installed in a single luminaire, for example, can differ slightly from each other. This process is called binning. The LED chips, whose characteristics are wider or narrower depending...

The lower the UGR value, the lower the glare. The UGR value (Unified Glare Rating ) is a dimensionless figure that indicates the degree of psychological glare of a lighting system in a standardised interior. UGR values are defined in steps for the range from 10 to 30, with a lower UGR value equating to lower glare. The UGR includes not only direct glare from the luminaire itself, but also reflected light from walls, floors and ceilings in a standardised room (DIN EN 12464-1). The actual UGR depends on the installation situation of the light source, the position of an observer and the actual structure...

Light spectrum All LED chips used by LED2WORK have a wavelength of 400 nm to 800 nm. Light ergonomics: well illuminated work areas. Light from LED2WORK also contributes to ergonomics in trade and industry. Ergonomic working lights for ergonomic working - that is our motto. Our LED industrial luminaires developed with under the aspect of improving light quality, lighting conditions and lighting atmosphere. The continuous further development with product solutions for better vision and work and the associated health aspects make us a strong partner for LED workplace and industrial lighting. The...
