DALI: Forerunner of Today’s Breakthrough Lighting Technology

The power of lighting has been obvious to architects for centuries, but now, because of the path blazed by digital addressable lighting interface (DALI) control systems, specifiers consider it part of their province as well.DALI is the forerunner of even more sophisticated lighting technologies. Its impact on buildings, owners, tenants, occupants and the environment has been far-reaching. DALI became an accepted protocol of the lighting industry for networked ballasts in 2002. Each ballast with a DALI interface is addressable, meaning that it can be communicated with individually.
