For the long autumn evenings I had planned to convert the switch light to LED. This perpetual lamp change was now really on my mind. In addition, the luminosity faded after a short time and the lamps became darker and darker. I had already experimented with some LEDs in the last few weeks and had the final solution now. The conversion of the 10 LED can be done easily in 2-3 hours, the result can really be seen. cht and can also convert to the big incandescent lamps if necessary. I quickly wrote a guide for the posterity. In a few weeks I forgot everything anyway. Next I will get ready for the lighting for the climate. It also dimmes in front of me.
