what are the difference whit 0-10v and dali dimmable? Can i use all the T5 tubes whit both models and dim the tubes?what would be the best option to buy now?please can someone explain the difference of both models to me.sorry for the stupid questions but did not find any fag for the difference of the models anywhere.

the tubes don't matter

DALI or 1-10V-interface describes how the light bar and the ProfiLux are connected

DALI has more options because it is a bus interface, but you need additionally the card PLM-DALI

Ok,
now i know what to bye.i think i go whit the dali option.
