Yes, this is the perfect controller for a lantern that uses 12V LED lighting and can run off a 12V battery.
PWM stands for “Pulse Wave Modulation”. The technology is used to control dimming with LED lights. In some cases you can dim LED lights by reducing voltage but a better way (and the only way with some LEDs) is to keep the voltage constant but “pulse” it. That’s what PWM does… it pulses more frequent (bright) or less frequent (dim) 12V voltage to the LED. We offer several controllers based on PWM technology:
