how hot do christmas lights get

Christmas lights are designed to produce heat and light, but they're not designed to generate enough heat to be dangerous. The heat from a string of lights is usually less than a single light bulb. However, it's always important to make sure that the lights are well-insulated and installed correctly to prevent overheating. Additionally, if you're using a lot of lights in one area, you may want to space them out to ensure adequate airflow and prevent the area from becoming too hot.
