If your house wall is insulated, be sure to take this into account when installing outdoor wall lights. It is important that the façade has sufficient load-bearing capacity to withstand the weight of the outdoor lights.
Among other things, there are Special insulation dowels on the market that are suitable for different purposes. For example, if the external insulation is polystyrene or mineral wool, which is usually the case, conventional expansion plugs will not usually hold. Instead, spiral-shaped insulation plugs are recommended.
Instructions for the correct installation of the light are provided by the respective Assembly instructions.
