V-Pro series dimmers are designed for use with LEDs and they are also suitable for halogen and incandescent lighting, most dimmable electronic transformers and with no minimum load, are suitable for dimmable low energy lighting. The V-Pro Series, eliminates Dimmer Buzz For GLS Bulbs, GU10 Lamps, and LV Transformers Including Trailing Edge Loads and is equipped with Self Re-setting Overload Protection, so is able to handle overload situations, for example, if the wattage of the bulbs/lamps are accidentally too high on a circuit. This is achieved by the dimmer cutting out before there is any damage, (if the watts are grossly overloaded), until the load is reduced. The dimmer also contains a heat sensor which again stops damage to the dimmer, if it becomes too hot. Box ContainsJQDP254W
