Read full descriptionHide full description
The RLT System sends broadcast signals through the Bluetooth of the mobile phone, and can simultaneously control all the lamps within a radius of 5 meters, such as controlling the on/off of the lamps, setting the brightness, running time and pulse frequency of the lamps. The Bluetooth broadcast signal will not be sent all the time, but only when the command is sent. The lamp will store the received command and execute it. When multiple APPs are controlled at the same time, the lamp will only execute the last command received.
