I ordered to smaller experiments to make the warm-white LEDs with it, but as well as convert solar lights that create an uncomfortable cold light to warm white. This I have done with 2 different solar lights and it works. For info. All LED Solar lights are in parallel without Vorwiederstände not connected in series. Therefore the enclosed Vorwiederstände are not need. The Vorwiederstände 470Ohm are chosen so that you can operate the LED at 12V. The LED also give a warmer light from LEDs compared to the cold in the solar lights.
