smart lighting PLUG-AND-PLAY LUMINAIRE CONTROLLER The Owlet IoT luminaire controller is based on the 7 pin NEMA socket. The node can be easily plugged in and replaced without any tools.

PRECISE ENERGY CONSUMPTION MEASUREMENT The nodes incorporate a built-in utility grade energy meter that offers the highest metering accuracy available on the market today (<1% for the complete dimming range). SAFE FALL-BACK SCENARIOS As safety for all is the primary objective, multiple technologies ensure that the system is switched on and off in complete security. INTUITIVE USER INTERFACE The Graphical User Interface (GUI) was developed with the latest web-based application tools. Every user can organize his/her dashboard in such a way that the most relevant topics or parameters appear first. OPERATIONAL BENEFITS One of the unique assets of this dynamic lighting management system is its capacity to implement, adapt and reproduce lighting profiles and driver settings, which are typical for public lighting networks. Thanks to Schréder’s experience and indepth expertise as an outdoor lighting specialist, the Owlet IoT system provides extended operational features which simplify maintenance.

Owlet IOT project: San Jose, USA Switching to energy efficient LED luminaires fitted with the Owlet Nightshift System, the city of San Jose, California has reduced its energy costs and CO2 emissions by 47 percent. The city of San Jose has achieved a milestone in one of the largest streetlight conversion projects ever launched in the U.S.A. The city's aim is to get electricity consumption for street lighting down from 34 million kWh in 2007 to just 17 million in 2022, and to use electricity from renewable sources. The city has started to retrofit more than 18,000 fixtures equipped with low and high-pressure sodium lamps to energy efficient LED luminaires equipped with the Owlet Nightshift control system. This project is an important goal of the city’s award-winning San Jose Green Vision, which aims to enhance visibility and safety at night while reducing energy and carbon emissions. Schreder is honoured to helped the city of San Jose to achieve this milestone. A total of 18,127 luminaires are replaced at a stretch of 128kms in the south-east area of the city. The smart lights are equipped with a LuCo-PD a technique which enables the luminaires to extend their basic lifetime by reducing the initial level of light (to avoid over lighting). It will also be dimmed during the night when there is little traffic on the roads so that they will use up to 60 per cent less electricity than the sodium based lamps. A total of 6,000 of these smart luminaires were installed for the in February, 2017. The entire installation will be finished for May. The Mayor of San Jose, Sam Liccardo stated “We are celebrating a greener, brighter, smarter San Jose.”
