The DALI is a non-proprietary
digital communication protocol that allows communications
between a DALI ballast and the lighting system. Tridonics,
Advance Transformer, and OSRAM SYLVANIA currently offer
DALI ballasts. The key features of the DALI ballast
communications for obtaining operating status and
performance of luminaires.
fixture control which allows users to re-configure
space lighting groups without changing the wiring,
easily implement load-shedding functions, and integrate
a fixture into multiple control zones.
user to mix and match ballasts from multiple suppliers
and obtain consistent control operation.
elimination of costly installation errors due to reversing
control wiring at ballast or control terminals.
easy addition of DALI-based wall controls and other
devices because a two-wire communications bus is used.
This feature greatly reduces labor and installation
