After more than 5 years with a possible transformer set, which was flashing spots, when he extinguished the downright not, what happiness to finally have a properly functioning lighting. Very easy to set up (fortunately because the record is really reduced to an absolute minimum, and again ...), this transformer, after a month of use, gives complete satisfaction on lighting with 3 bulbs G4 20W each . See with time, but for now, everything is perfect.
