The FIBARO Walli Dimmer is a small flush-mounted module combined with a visually appealing switch, which can be used to dim the existing lighting. So you always adjust your lighting to the respective occasion. The small FIBARO Walli dimmer measures the active power as well as the energy consumption. With its LED ring you are informed about the current energy consumption. The installation is easy and can be carried out according to your individual wishes. Use the included switch, which was inspired by the timeless elegance and flowing appearance of a pearl, or your own switch series (GIRA System 55**, Legrand Celiane, Schneider Odace). The FIBARO Walli Dimmer can be used for the following luminaries: conventional incandescent lamps and halogen ELV halogen lamps and dimmable LED bulbs (with electronic transformers) MLV halogen lamps (with ferromagnetic transformers) dimmable LED bulbs dimmable compact fluorescent CFL tube lamps The FIBARO Walli Dimmer can also be used in combination with the well-known FIBARO Bypass 2 (FIB_FGB-002) to dim and switch LED lamps and energy-saving lamps without flickering.
