    alright... you have to download and install this library
    https://github.com/fdebrabander/Arduino-LiquidCrystal-I2C-library
    or install it trough the IDE(?)

    instead of the normal library include at the start you put this
    #include <LiquidCrystal_I2C.h>

    at line #41 you put this instead
    LiquidCrystal_I2C lcd(0x27,16,2);

    at lines #238 #239 #240 you put this instead (i put the initialization after, it works)
    lcd.begin();
    lcd.backlight();
    initializeGraphics();

    it works with the latest(?) I2C controller with the 3 solderable pads to select a different I2C address (not needed), they are under the potentiometer (that it's better to adjust)

    you welcome, if you are talking about vintage VFDs (tube or pack) i would really like to know if it works ok or not (it should, in my opinion) if you remember it, come back... maybe power the CD4017 with ~16 volts if they require more juice

    not at all, these are chinese 10W leds, i bought em 2€ for five pieces shipped... honestly i'm not sure about quality and efficiency but they seem pretty ok, the "browned one" you saw may have 1000 hours of work (not impressive but it seems still 100% in shape), they anyways have the classic imbalance between chips when you turn em off or power em with microamperes
