DIAL Spotlight: Putting People, Conversations and Lighting into Focus
Next year, we will introduce a new format. With DIAL Spotlight, we want to bring interesting topics, inspiring people, and influential brands into focus – across lighting design, engineering, and building automation. To kick things off, we will be talking to Zumtobel about the role of Human Centric Lighting (HCL) in lighting design. Join us online: 21 January 2026, 12:30 p.m. (CET).
