Operate the transformer with 4 halogen lamps A 20 watt than lighting over the dining table. "Drive" After switching the lamps delayed a bit high, a nice effect. The dimmer also reacts slightly delayed, but I did not feel a disadvantage. Absolutely silent operation. After turning off the lights always start with full illumination, the last setting is therefore not accepted. Even so I can live with that. From me a strong buy recommendation.
