Our presentation will look at both wired and wireless DALI solutions for digital lighting control, and how each platform offers possibilities for both new and retrofit applications. In addition we will discuss the role of interoperability and how choice will ensure project cost and performance is both optimised and extended. Subsequently we will examine the benefits of certain DALI commands, and the value of data as a tool to optimise and extend the useful operating life of DALI controls.
