Just bought an awesome Blue Glowing Berry.
I’m not sure whether it has built-in current limiting resistor.
If I apply 12V for a brief period of time, the blue light is impressively bright to my liking; If I put a 1k resistor, the blue light is no longer that impressive. But I am not sure whether I can safely apply 12V to it without the current limiting resistor for extended period of time.
Have a great weekend.
