I have an led string with a multi function controller which supplies 240v dc to the string. There are three wires coming out of the MFC and then five between most of the LEDs The string has three section of around 130 LEDs in each section. Each section starts with two LEDs without a resistor and then six with resistors (can't get my head round that !!). Can I modify each section of this string to work with a lower voltage ? Thanks.
