In the field of digital ballasts Dimlux is the most quiet system, there are hardly any vibrating or buzzing noises and no buzzing and/or chattering noises in the relay can be heard. The Dimlux can be used as normal (digital) ballast in a normal system with relay and timer. However, if the Dimlux is used in combination with the Maxi Controller you will get the maximum performance and can use all the features of the Dimlux in its full advantage.
