OPTOTRONIC® Outdoor Programmable LED Drivers with DEXAL® Technology

An intra-luminaire, bi-directional digital communications interface

The OSRAM OPTOTRONIC Programmable Outdoor LED Driver with DEXAL Technology, is a non-proprietary, intra-luminaire interface that enables bi-directional communications between the driver and the fixture-integrated component. It provides exact luminaire-specific data, including diagnostics, to light management systems. Fixture manufacturers can design smart fixtures and streamline the configuration process by leveraging DEXAL as a standard bi-directional communications interface.
