The Lutron Caseta In-Wall Smart Dimmer Switch PRO is UL listed to work with up to 250W of dimmable LED, or 1000W Incandescent/Halogen bulbs. The Caseta Dimmer Switch PRO is also compatible with LEDs with integrated drivers, magnetic low-voltage loads, as well as Phillips Mark 10® ballasts and Lutron Hi-Lume 1% 2-Wire (LTE) LED drivers. Neutral wire connection is optional for standard LED bulbs, but required for MLV loads, LED drivers, dimmable ballasts, and power modules. Minimum load with neutral connected is 10W, without neutral is 25W. Pair a Lutron Pico Remote Control (PJ2-3BRL-Gxx-L01) to the Caseta dimmer switch PRO and mount it anywhere to dim the lights from any location using the Pico wall box adapter (PICO-WBX-ADAPT); Pico Remote and wall box adapter sold separately. The Caseta Smart Dimmer PRO can be used in single pole and 3-way applications (when wired to existing 3-way switches). A Pico Remote control is required to create 4-way or multi-location applications. Use the Lutron Smart Hub to connect the Caseta Smart Dimmer Switch PRO to leading smart home devices - including Alexa, Apple Home, Google Home, Ring, Sonos, and more. The smart hub doesn't rely on Wi-Fi to control lights which avoids slowing down internet speeds and allows you to stay connected even when the Wi-Fi goes down. The hub also unlocks advance features like Smart Away which randomly turns lights on and off, to make it look like you're at home, even if you're away (Lutron Smart Hub, L-BDG2-WH required). Pairs perfectly with Lutron Claro wall plates for consistent color matching (sold separately).
