Voltage Rating We need to double-check that the voltage rating of the photocell matches up with the voltage rating of the LED light you are trying to control. As an example, you may have lights in a campervan that are 12V DC. A mains-powered 230V AC photocell is not going to be compatible.photocell is not going to be compatible.
