This is a wall plug dimmer than can be placed between a British Standard wall outlet and electric devices, plugged in by cord. It can dim all incandescent lights, high voltage halogen lamps and transformers operated low voltage lamps without restriction. Special optimisation functions support the dimming of the majority of dimmable LED lights and Compact Fluorescent Lights (CFLs). The device is IP20 rated and can therefore only be used in dry environments. The device offers a Baby-Dim Function which dims down a lamp from a defined level into another defined level in a longer but also definable period (e.g. 20 minutes). An automatic Light-Off function and programmable dimming and switching behaviour makes the device a very flexible tool for inhouse lighting.
