A legend turns 50!


With outstanding qualitative properties, our dust- and waterproof light fitting 161 has earned a legendary reputation over half a century. Since its introduction in 1972, we have continued to develop and improve it. Then as now, it impresses with its unreachable quality Made in Germany. And the almost unlimted options to customize it leave nearly nothing to be desired.
With the new 161PX PROXIMA, we have now perfectly engineered the legendary 161 to LED technology and set a new benchmark. A luminaire you can always rely on.
You will not find a better dust- and waterproof light fitting for rough industrial environments.
