Using these exterior LED wall lights is simple. First, make sure you have a licenced electrician install them as required. The installation instructions are in each product box. These lights can be used in various outdoor settings as long as the ambient temperature stays between -40 and 85°C. To keep them in good condition, regularly check if there is any dirt or debris on the surface and clean them gently with a soft cloth. Since they have an IP65 rating, they can withstand some water and dust, but avoid exposing them to extreme water pressure. If you encounter any problems within the 2-year warranty period, you can get a replacement.
