Series EWD

The luminaires of the EWD series ae designed to provide a onesided backlight or directional lighting with high uniformity on different architectural and artistic objects located outdoors. The simple compact design with excellent thermal characteristics and a high level of hermetization ensures long and reliable operation of the luminaire even in harsh weather conditions. The fixing mechanism allows quick and easy installation on building facades, ceilings, walls and other surfaces. The EWD series successfully can be used for lighting and highlight patterns of buildings, bridges, monuments, and more.
Using a special optical system (a combination of lenses) or mat plafond with luminairies of the  EWD series a wide range of  lighting projects, highlighting certain aspects and patterns of the architectural style of buildings and facilities can be achieved. In realizing specific architectural projects the luminaires can be made with different colors of the light emitted.
