NettetIn the lighting industry, “cold cathode” historically refers to luminous tubing larger than 20 mm in diameter and operating on a current of 120 to 240 milliamperes. This larger-diameter tubing is often used for interior alcove and general lighting. NettetThe cathode is the short lead and there may be a slight flat on the body of round LEDs. If you can see inside the LED the cathode is the larger electrode but this is not an official identification method. Soldering LEDs LEDs can be damaged by heat when soldering but the risk is small unless you are very slow.
