Caseta Wireless by Lutron allows you to control your lights from anywhere within your home using the Pico remote control (sold separately) or from anywhere with your mobile device via the FREE app and Caseta Smart Bridge (sold separately). The Caseta ELV+ Dimmer is designed to control many load types: 500W INCAND/HAL/ELV, 400W of MLV, and 250W of dimmable LED/CFL bulbs (neutral wire connection and 10W minimum load required for all load types). The dimmer is set to control ELV, incandescent, halogen and many compatible LEDs, however it is phase selective so the dimmer output can be changed for MLV and certain LED bulbs with simple button press programming. The Caseta ELV+ Dimmer is a great solution for LED fixtures with integrated, built-in drivers, ELV track lights and problem LEDs that may prefer an ELV dimmer. Easily replaces your existing switch in as little as 15 minutes; NEUTRAL WIRE REQUIRED. INCLUDES: (1) Caseta ELV Dimmer Switch; coordinating wall plate sold separately.
