About This
- 【20kHz High-Frequency for Silent & Flicker-Free Light】 Experience ultimate quietness. Our 20kHz high-frequency PWM dimming technology pushes electrical noise beyond human hearing, eliminating buzzing sounds. By adopting this high-frequency PWM, it eradicates visible light flicker at its source. Enjoy perfectly stable and silent illumination from 1% to 100% brightness.
- 【Advanced Flicker-Free Technology & Eye Protection】 This controller utilizes high-frequency PWM technology to eliminate visible light flicker, a key cause of eye strain and headaches. The stable, consistent light output mimics natural daylight, providing superior visual comfort for prolonged reading, work, or relaxation, effectively protecting your eyesight.
- 【PWM LED Type】Control monochrome(single color) and Dual white (CCT) LED strip LED String LED bulb like FCOB 5630 2835 3528 5630 5730 5050 3014 etc Without IC chip 2 wires(V+,V-), 3 wires (V+, CW, WW) PWM LED strip light.
- 【Dual-Mode WiFi & Bluetooth Connectivity】 Enjoy maximum flexibility with built-in dual-mode connectivity (Wi-Fi and Bluetooth). Set up and control your lights directly via Bluetooth without a Wi-Fi network, or use Wi-Fi for full remote access. In the app, adjust brightness, fine-tune color temperature (2700K-6500K), and create smart scenes.
- 【3 Control Methods】 This 2.4GHz WiFi CH21W LED controller supports simultaneous operation through: (1) RF Remote Control: Works with 2.4GHz remotes (RC01RFB, RC02RFB, RC07RFB, RC08RFB, WR02RF). (2) Smart App Control: Use Tuya Smart or Smart Life App via 2.4GHz Wi-Fi. (3) Voice Control: Compatible with Alexa & Google Home. All 3 control methods work together seamlessly.
- 【Power & Installation】 Input Voltage: DC12V/DC24V. Output: 7.5A per channel. The controller operates in a wide temperature range (-25°C to 40°C). The required power supply must match your LED strip's voltage (e.g., DC12V for DC12V strips, DC24V for DC24V LED strips). Please note this package includes only the controller - LED strips and compatible power supply must be purchased separately for complete installation.

What Customers Ask Most
Choose lighting based on your space.
LED for everyday use, smart lighting for convenience, outdoor lighting for safety, and decorative lighting for atmosphere.
For most rooms, 800–1600 lumens works well.
Higher lumens = brighter light.
2700K–3000K = warm & cozy
4000K = neutral & clean
5000K+ = bright & daylight
Solar lights are great for pathways, gardens, and ambiance.
For strong brightness, choose high-lumen models.
