Using advanced PWM (Pulse Width Modulation) control technology, the change effect is smooth and flicker-free. The input voltage adapts to DC 12-24V with input polarity protection. The wireless remote control is non-directional with a control distance of no less than 20 meters. The remote control features low power consumption and long standby time. Especially suitable for indoor home and commercial applications.
