LED lighting should be controllable so that one can create different moods and different lighting scenarios within a project. The light fixtures can be either dimmed through a phase-cut driver or an analog driver based on the automation provided at your project.
However, the most advanced way of controlling lighting is through the DALI system where each and every light fixture in your project can be digitally controlled and you have the freedom of making any combination with the light fixtures depending on your personal requirement.
DALI can be easily integrated with automation and lighting scenario settings.
