Elevate your LED strip lighting experience with the LM-CH21 Series. Engineered for professional-grade lighting applications, this smart LED controller offers ultra-high 20KHz PWM dimming to ensure a completely flicker-free environment—ideal for high-speed photography, studios, and high-end residential projects. Whether you are managing Single Color (Dimming) or Tunable White (CCT) LED strips, the LM-CH21 provides precision and stability.
RF 2.4G Control Only
Perfect for dedicated remote control setups without the need for a network. Compatible with LM-RC01RF (dimming), LM-RC02RF (CCT) handheld remotes and LM-WR02RF (dimming and CCT) panel wall remote.
WiFi + Bluetooth + RF
Smart ecosystem integration for "Tuya" App control and voice assistants.
20KHz High-Frequency PWM: Eliminates stroboscopic effects, protecting eyesight and ensuring perfect video recording quality.
Dual Output Modes: One controller supports both Static White and CCT (Tunable White) LED strips.
Sync Control: Multiple controllers can be synchronized to ensure consistent lighting effects across large installations.
Smooth Dimming: 0-100% stepless dimming with logarithmic curves for a natural visual transition.
Pro Tip: Manual Configuration Required
Before pairing your LED strips, use the onboard SET button to toggle between (short press to switch):
Output Mode: Single Color Mode (White indicator quick flash) vs. CCT Mode (Yellow indicator quick flash).
PWM Frequency: 2KHz (Standard) vs. 20KHz (High Frequency).
