The stringent shape of "wotek" is clearly defined by the accentuated edges. The light effect, however, comes to the fore as it is almost without shadow and provides unobtrusive illumination. Whether square or long, there is a wide range of variants for many applications. The entire "wotek" family of luminaires is designed for IP54, and as a result further extends the range of applications, just as with the emergency lighting variants available. In addition, there is also the improved maintenance factor of the LED luminaire.
