Long lifespan of over 100,000 hours, thanks in part to a sustainable product concept and durable components. Highly efficient LED technology with up to 172 lm/W, providing uniform and glare-free illumination. Light distributions are based on our non-yellowing PMMA lens platform. Mixing and rotating the lens plates for different light distributions is possible upon request. Easy installation thanks to the standard pre-assembled connection cable. Mast flange for pole dimensions of 60/76 mm with tilt adjustment (-15°…+20° (top), -20°…+20° (base)) included. All variants of the Streetlight SL 31 can be individually parameterized later with our SITECO® service box or wirelessly and voltage-free using our Desk-Remote variant via our SITECO® handheld. The Easy and Easy LST variants represent the basic versions of the new Streetlight SL 31. The variants can be operated as ON/OFF lights, with a Night-Set profile, or Lumen-Switch. The Easy LST variant also has the function to be controlled via a reduction wire. Smart-City-ready: Future-proof with two optional Zhaga or NEMA interfaces (7-pin) for state-of-the-art light control, wireless networking, and versatile sensor technology. Desk-Remote: voltage-free transmission of data to the light via application-optimized NFC/RFID function, even through the packaging.
