My company will be involved in the programming of a new 25 story building with every single light fitting being controlled by a DALI ballast. Each level will have its own C BUS network with some floors having as many as 6 DALI gateways. I have done some work with DALI ballasts before and am not a big fan at this stage. It is very hard to get reliable information. Has anyone done a DALI job to this scale? , What is the best and most reliable DALI programming software?, We are using OSRAM ballasts. I want to be confident with this system but to date I am far from it. All comments appreciated Kelly
