This four-pack from TREATLIFE offers a practical solution for managing lighting in multiple rooms or zones. Each unit functions as a single-pole smart dimmer, designed to replace existing wall switches where a neutral wire is present. The dimmer is compatible with LED, CFL, and incandescent bulbs, providing smooth dimming capability from bright to low levels without flicker. Constructed with a durable polycarbonate shell and a clean, minimalist faceplate, the switch has a tactile, responsive button and a subtle LED indicator.

The internal components are engineered for consistent performance and long-term reliability, with a rated load capacity that supports a wide range of household bulbs. Operating on a stable 2.4GHz Wi-Fi connection, the switch pairs easily with the TREATLIFE app for scheduling, group control, and remote access. Voice commands are supported through Amazon Alexa and Google Home, allowing hands‑free adjustments. The dimmer remembers the last brightness setting and features a built‑in delay for fade‑on or fade‑off routines.

The response time is instantaneous, and the switch maintains its settings even after a power outage. Installation requires a neutral wire, and the unit fits standard US wall boxes; detailed instructions and wire connectors are included. The dimmer handles a maximum load of 300W for LED/CFL and 600W for incandescent, making it suitable for most residential lighting circuits. It supports over‑temperature protection and surge protection for added safety.

During operation, the switch remains cool to the touch, and the dimming range is adjustable via the app to fine‑tune minimum brightness. The physical switch provides tactile feedback, and the backlit indicator can be toggled on or off. This four‑pack offers a cost‑effective way to upgrade multiple locations, with consistent performance across all units. Ideal for homeowners, renters, or property managers looking to integrate smart lighting without replacing bulbs or adding hubs, this switch works with any standard neutral‑wire setup.

The dimmer is particularly suited for living rooms, bedrooms, and hallways where adjustable lighting ambiance is desired. Compatible with both incandescent and dimmable LEDs, it covers a broad range of bulb types. The package provides four switches, four faceplates, and all necessary hardware, delivering excellent value for those outfitting an entire floor or multiple rooms.
