How much do lighting controls save?
Controls save energy only when they reduce output or hours. In meeting rooms, toilets, stores and aisles that are often empty, the saving can be large; in a busy open-plan office less so.
What is DALI?
DALI is a digital lighting control standard that lets each fitting be addressed, dimmed and grouped individually, with scenes and fault reporting.
