AC Triac Dimming Series
2 sub-categoriesTriac lights are directly powered by line voltage, and dimming these lights at the high voltage end is called Triac Dimming. Traditional Triac dimming is achieved through in-wall Triac dimmers.
MiBoxer Mi-Light Triac Control brings intelligent control to traditional AC light dimming, it's compatible with RF, WiFi, and Zigbee wireless protocols, which allows you to adjust the AC LED lights and traditional filament and halogen lamps via RF remote, smartphone or voice command.
Line Voltage Triac Dimmer Switch
The Triac dimmer switch panel adopts trailing-edge phase cut dimming technology, enabling smooth dimming from 0% to 100%. The Triac light dimmer works with Triac dimmable LED lights, halogen lamps, and conventional incandescent lamps.
Utilizing Zigbee, WiFi technology, the Triac wall dimmer support Tuya smartphone app and voice assistant control to achieve smart control over traditional incandescent light and AC Triac LED lights.Users can directly adjust brightness through the touch panel or the rotary knob, which is simple to operate.
Besides, the Triac LED dimmer supports RF remote control. When controlled by the same remote, the LED Triac dimmer switch transmits signal from remote automatically to another dimmer, thereby synchronizing the working mode with other dimmer.
Triac Dimmable Push Button Dimmer
The dimmable Traic switch with push button supports 0-100% flicker-free dimming for dimmable LED light, incandescent lamps and high voltage halogen lamps. When connected to PUSH dimmer switch, the phase cut dimmer offers light on/off control and continuous dimming function, supporting user to set the lowest brightness by key.
Besides, the Triac LED dimmers are designed to meet various smart home needs, including RF dimmer, RF Zigbee dimmer and RF WiFi dimmer, supporting Tuya app, third-party voice and RF remote control. Under the control of the same RF remote, the Traic light switches dimmers perform automatic signal transmission and mode synchronization function.
The AC Triac RF+ PUSH dimmer can be installed in a standard 86*86 wall junction box. The over-load and over-heat protection of this phase cutting dimmer ensures the safety during use.

Why Choose MiBoxer (Mi-Light) Smart TRIAC Dimming?
MiBoxer (Mi-Light) smart TRIAC dimmers provide a convenient way to bring wireless control to compatible line-voltage lighting without necessarily replacing existing light fixtures. Instead of relying only on a traditional in-wall dimmer, users can add RF remote control, smartphone-based operation, or smart home integration through a compatible TRIAC dimming module.
The range includes RF-only, Wi-Fi + RF, and Zigbee + RF dimming solutions, allowing you to choose a control method that fits your home or project. From upgrading an existing room to building a connected lighting system, MiBoxer offers flexible options for controlling compatible TRIAC-dimmable LED lights, incandescent lamps, and halogen lamps.
Upgrade Existing Line-Voltage Lighting with Smart Control
For renovations and retrofit projects, replacing every light fixture or installing a separate low-voltage control network may not be necessary. Where compatible line-voltage lighting and suitable wiring are already in place, a MiBoxer TRIAC dimming module can add wireless dimming and remote operation while retaining the existing lighting fixtures.
This approach is particularly useful for ceiling lights, wall lights, decorative fixtures, and other mains-powered lights that support compatible phase-cut dimming. Depending on the selected model, users can control lighting through an RF remote, a wall-mounted push button, a smartphone app, or a supported smart home platform.
**Important:** The connected lamps must support the dimming method used by the selected module. Not every LED lamp labeled "dimmable" is compatible with every TRIAC dimmer, so check the lamp specifications and dimmer compatibility before installation.
Choose RF, Wi-Fi + RF, or Zigbee + RF Control
MiBoxer offers different control options to suit different smart lighting requirements:
RF + Push Control: A practical choice for users who want handheld remote operation and convenient local push-button dimming without requiring a Wi-Fi network or Zigbee gateway. Compatible models, such as TRI-C1, support RF remote control and push-switch operation.
Wi-Fi + RF Control: Suitable for users who want both RF remote control and smartphone-based lighting operation. Compatible Wi-Fi models, such as TRI-C1WR or TRI-PW, can support app-based control through the designated platform and network configuration.
Zigbee + RF Control: A good option for projects that use a compatible Zigbee smart home system while retaining RF remote control. Models such as TRI-C1ZR or TRI-PZ support Zigbee-based integration and RF operation; app and smart home functions may require a compatible Zigbee gateway.
The best option depends on whether you prefer standalone remote control, app-based access, or integration with an existing smart home ecosystem. Always confirm the control protocol and gateway requirements for the exact model.

FAQ About AC Triac Dimming Series
Clear answers from our technical support desk on line-voltage phase cutting, wiring connections, and smart wireless protocol integration.
An AC Triac dimmer regulates brightness by chopping portions of the alternating current sine wave at line voltage (100–240V AC). Unlike low-voltage DC PWM dimmers that switch 12V or 24V power on the secondary side, a line-voltage phase-cut dimmer sits upstream between the mains supply and the fixture or driver. It allows you to adjust brightness across existing two-wire mains circuits without routing extra low-voltage control cables through finished walls.
An AC Triac dimmer cannot connect directly to DC LED strip lights without destroying them. The high-voltage phase-cut output must feed a phase-cut dimmable LED driver, which steps AC mains down to regulated 12V or 24V DC while translating the chopped AC waveform into flicker-free DC output. If you want direct wireless strip control without an intermediate phase-cut driver, check our controller selection guide to evaluate secondary-side DC controllers.
A triac dimmable LED fixture almost always performs cleaner with trailing-edge (ELV) phase-cut dimming. Leading-edge TRIAC dimmers were engineered for resistive incandescent filaments; their abrupt voltage spikes cause audible acoustic hum, magnetic ringing, and driver overheating on capacitive LED power circuits. Trailing-edge dimmers shut the waveform off smoothly at the zero-cross, reducing inrush current and eliminating buzz on solid-state LED power supplies.
A standard dimmable triac module like our TRI-C1 handles up to 1.5A, which translates to roughly 150W of capacitive LED load on 110V AC or 300W on 220V AC. Even though resistive incandescent ratings might reach 300W–600W, capacitive LED drivers draw heavy inrush current at turn-on that can weld internal relays. For large architectural circuits exceeding 150W of LEDs on 120V lines, step up to our 500W smart triac dimmer to prevent thermal overload.
Connect a standard normally open momentary wall switch between the AC Line terminal and the dedicated Push input on the controller. A brief tap under 0.5 seconds toggles the AC line voltage on or off, while holding the push button down initiates smooth continuous dimming between 1% and 100%. The controller reverses dimming direction with each subsequent long press and stores the final light level in non-volatile memory.
A Zigbee-enabled triac dimmable module like the TRI-C1ZR links directly with standard Zigbee 3.0 gateways, including Philips Hue, Tuya Zigbee, and Amazon Echo hubs with built-in Zigbee radios. It pairs through the standard touchlink commissioning procedure and exposes full on/off, dimming curve adjustments, and scheduling inside your home automation dashboard. It also responds concurrently to 2.4GHz RF handheld remotes and physical push-dim switches.
You can synchronize or isolate up to three independent AC circuits using multi-zone controllers from our push button dimmers sub-category. Modules like the PUSH1-3 receive 2.4GHz RF signals from multi-zone handheld remotes or rotary wall panels, allowing one switch to control grouped downlights or separate cove circuits across a room. Each zone maintains its own independent phase-cut output and local push-switch terminal for manual override.
Every model in our AC Triac dimmer lineup requires a dedicated neutral wire inside the junction box to operate reliably. Wireless transceivers (RF, Zigbee, and WiFi) draw continuous quiescent power to stay online; running them on a no-neutral loop causes micro-amperage leakage through LED drivers that results in visible ghost glow when switched off. If your wall box lacks a neutral run, place the module inside the ceiling fixture canopy where Line and Neutral are both accessible.
