PulseWorx UPB LED/CFL Dimmer Wall Switches are your one stop for light dimming control. These switches were specifically designed to operate all major types of dimmable light sources, including LED lights, CFL lights, fluorescent lights, inductive loads, magnetic LV loads, incandescent lights and halogen lights. They offer smoother dimming throughout the light's range, and an adjustable minimum dimming level to reduce drop-off and prevent flickering. A multi-color (Blue, Magenta, Red or Off) LED guides you through the dark. Tapping the rocker switch turns lights on/off, while holding it down dims/brighten lights. Separate brightness levels are chosen for single-tap and double-tap events. Sixteen selectable fade rates (instant-on to 1 hour) give you absolute flexibility. Each switch may become a member of 16 individual scenes, 250 different scenes per system. Switches can store a preset lights-on level and fade rate for each scene, allowing you to install a sophisticated lighting system at a fraction of typical costs. These switches are designed to be an integral part of a complete PulseWorx Lighting Control System. Like all PulseWorx devices, the Dimmer Wall Switches use UPB technology to communicate with other UPB-compatible devices over your existing electrical wires. No new wiring is required. When initial configuration is complete, a single push of a button is all you need to simultaneously activate any group of lights (or virtually anything else that connects to AC power wiring) throughout your house. Three-way (or multi-way) light switch functionality can be obtained by connecting one (or more) RWS "remote" switches (sold separately) to its yellow traveler wire. The switch can also be configured as a two-button transmitter. Select from a list of commands to be transmitted when each rocker button is tapped, held or released. This allows the switch to remotely control other devices or update indicators. Manufacturer Part #: WS1DL-10-LA. Color: Light Almond.
