const int LampControl=3;                   //define var
void setup() {
  pinMode(LampControl,OUTPUT);            // Set pinMode
}
void loop() {
  digitalWrite(LampControl,HIGH);//Light up lamp 2s
  delay(2000);
  digitalWrite(LampControl,LOW);//Turn off lamp 2s
  delay(2000);
}

Result

The lamp will blink like an led (This is a demo, we do not suggest you operate your lamp like this continually, since it will reduce the service life.)
