how many led christmas lights can i string together

The number of LED Christmas lights you can safely string together depends on several factors, such as the wattage of the lights, the voltage rating of the power supply, and the amperage rating of the circuit. Generally, it's recommended to use no more than 25-50 LEDs per circuit to avoid overloading the power supply and causing a fire hazard. It's also important to follow the manufacturer's instructions and use appropriate safety measures when handling electrical equipment.
