TS-K(WT) is a rotary glass panel dimmer designed for both smart and traditional lighting control. It can be used in two ways: either as a manual rotary dimmer without WiFi, or as a smart device connected via the Tuya Smart or Smart Life app. It also supports voice control through Alexa, Google Assistant, Tmall Genie or Xiaodu when connected to WiFi. This model offers smooth, flicker-free dimming from 0 to 100% using a 256-level dimming curve.
This dimmer is suitable for directly controlling mains-powered 240V dimmable LED lamps, such as GU10 spotlights, or low-voltage 12V or 24V LED strip lighting when used with a compatible Triac dimmable LED driver. The internal DIP switch allows the installer to choose between leading edge or trailing edge dimming depending on the type of load.
Manual control is simple and intuitive. A short press on the knob switches the light on or off. Rotating the knob adjusts brightness, while a long press allows for fine control across the full dimming range. The dimmer also offers advanced settings including minimum brightness level selection and fade-on/off timing, all accessible via the SET key. Additional features such as scene creation, timers and music sync are available through the app when using WiFi mode. Bluetooth control is also supported after WiFi setup is complete, allowing local fallback control when the network is weak.
Available in white or black glass finish, this unit fits standard 86mm back boxes and suits a wide range of interior styles. It includes safety features such as overload and overheat protection with automatic recovery. Designed for both domestic and commercial installations, it offers reliable control and a modern appearance.

Who Is This Product For
This dimmer is ideal for customers who want flexible and modern lighting control in residential, hospitality, or commercial environments. It supports both direct 240V dimmable LED lamps, such as GU10s, and low-voltage LED strip lighting when used with a suitable 240V AC mains-dimmable LED driver for 12V or 24V systems. One important requirement is that this dimmer must be wired with both live and neutral connections on the input and output side. It is not compatible with installations where only a single live wire is available and is best suited for modern wiring layouts where a neutral wire is present.
Despite its advanced capabilities, this dimmer is also highly effective in smaller applications. It has been successfully tested to control a single 6.5W dimmable GU10 without issue, making it ideal for simple lighting zones with one or two fittings or small dimmable driver loads. It also works reliably with low-wattage 240V AC dimmable LED drivers. All Hi-Line branded dimmable products have been tested for full compatibility, and the dimmer is also suitable for use with most other quality dimmable LEDs and drivers. Installers benefit from an easy DIP-switch selection for dimming mode and straightforward configuration. Whether controlling one spotlight or a compact LED strip zone, this dimmer offers reliable performance with the flexibility to upgrade later to full smart control.
This product must be installed by a qualified electrician or lighting professional. All wiring must comply with current IEE regulations and local electrical standards. The installer is responsible for confirming compatibility, calculating appropriate loads and inrush current, and ensuring the safety and reliability of the installation.
Why Choose the TS-K(WT)
TS-K(WT) combines modern design with proven reliability, offering smooth, flicker-free dimming for both traditional 240V LED lamps and low-voltage LED strip setups powered by compatible dimmable drivers. Whether you're controlling a single GU10 spotlight or a full zone of LED strips, this dimmer delivers stable and consistent performance. It is simple to install, with clear DIP switch selection for the appropriate dimming mode and minimal setup required.
Smart features such as WiFi control, app integration, voice assistant support, timers, and scenes make it ideal for high-end lighting systems or smart home upgrades. At the same time, it can be used completely offline as a manual rotary dimmer for straightforward jobs. This flexibility makes it suitable for small single-lamp zones as well as larger, more advanced installations. Whether used in a home, hotel, office, or showroom, the TS-K(WT) is built to deliver professional results with minimal fuss.

Installation Notes
This product must be installed in a dry, well-ventilated indoor location using a standard 86mm electrical back box. Before switching on, the DIP switch must be set according to the load type being used, either leading edge or trailing edge. When connecting to LED drivers, ensure the surge current for all drivers combined does not exceed 130A. The maximum number of supported drivers can be calculated by dividing 200W by the rated input power of each driver. All installations must be carried out by qualified professionals and must comply with current IEE wiring regulations.
