KEDR (USI) are the most advanced industrial suspended luminaires. KEDR series luminaires are characterised with the slimest housings within the professional lighting class, the housing is only 7 mm thick. Innovative heat dissipation technology is implemented for the luminaires by installing inside them of the heaters of «FINFREE» specifically developed composition of heat-conductive materials. There has been no similar technology so far. KEDR (USI) luminaires are designed to be suspended, to ensure safety for luminaires installation there are designed placeholders for safety ropes. KEDR luminaries can be provided with additional optics to create the required illumination. Upon the request of a customer KEDR luminaires can be completed with LEDs of neutral white (4000 K) or warm white (3000 K) luminescence. The luminaires housings are coated with powder paint, a customer can choose the housing colour basing on RAL scale, structure elements are made of stainless steel and are weather-resistant. The luminaires are thoughtfully designed to allow for PSU replacement without the luminaire itself being dismounted.
