The LT124 is a twist-lock photocontrol for LED street, road and area lighting. Its zero-cross switching technology protects both the control and the LED driver at every dusk-on and dawn-off operation, while a 475J MOV and 10kV surge rating absorb what storms and grid events deliver. Sealed to IP67 and rated for at least 20,000 switching cycles at 50W load, it is built to be installed once and forgotten.
