The TC421 and T420 LED Time Controller are perfect for controlling a variety of LED Lights, from single color to RGBW and RGBWW, with 5 output channels, 24-hour cycle programming, and 30-minute section control of brightness and color for each channel. You may customize the schedule mode you want through your PC or APP client, then through the USB port or WiFi to download the required schedule to the Controller. You can set the mode effect for a certain period, edit multiple modes, delete redundant modes, and directly preview mode. The TC421 has WiFi capabilities, with two modes: AP mode and STA mode; at AP mode, your phone can connect to the WiFi LED Controller directly, while at STA mode, the connection is made through a router. The Timer Controller can control a load of LED changing effects in no more than five channels. You can use them for plant lighting, light boxes, signage lights, home decoration lights, etc. The TC420 version is also available for those who do not require WiFi capability.
