To adjust a dimmable LED bulb, a specially designed dimmer is required. Connecting an LED bulb to a traditional dimmer often results in irregular operation, with flickering light and a high probability of burning out the bulb. Our in-line button dimmer, on the other hand, is specifically designed to adjust any type of bulb: traditional filament, dimmable energy-saving, and dimmable LED. Designed and produced 100% in Italy, the button LED dimmer will allow you to adjust the light intensity in the most comfortable and safe way.
