New. Never used. Came off of lamps that arrived damaged in the shipment and were never installed. Comes as shown in the photos. Fast handling time. The nLight nIO EZ PH module is a low voltage control device integrated within Acuity Brands LED luminaires with eldoLED brand drivers. This smart device results in the luminaire being ?nLight-enabled? - making it both addressable as well as capable of digitally communicating with other nLight controls such as occupancy sensors, photocells, and WallPods. This allows for advanced operation and design flexibility ranging from stand-alone rooms to building and campus-wide networks. The embedded nIO EZ PH device can provide energy saving lumen management. With lumen management the device manages the luminaires LED light source such that constant lumen output is maintained over system life, thus preventing the energy waste created by the traditional practice of over-lighting. The nIO EZ PH will adjust the control level of the luminaire from its full lumen output to its minimum controlled level. nIO EZ PH Series devices operate identically to nEIO EZ Series devices that utilize the embedded/linear pack enclosure.
