One has only to turn up anything, then the light goes on, then you can settle down again. I can not judge if this is normal or not, in any case the dimmer for my imaginary application is unusable. Very positive: Have the money without hesitation, even including shipping costs, reimbursed, although my little one has gefleddert and shredded the instructions and I could not send them back with..
