Outdoor wall lights are an important part of the outdoor lighting system, and their material selection directly affects their performance, appearance and service life.
Weather resistance and corrosion resistance
Outdoor wall lights made of different materials have different weather resistance and corrosion resistance. Common materials include aluminum alloy, stainless steel, cast iron, etc. Aluminum alloy has high corrosion resistance and weather resistance, and is suitable for a variety of outdoor environments, such as the seaside, high temperature and humid areas, etc. Stainless steel has good resistance to oxidation and corrosion and is suitable for humid and rainy environments. Although cast iron is strong and durable, it has poor corrosion resistance and is prone to rust in humid and rainy environments.
Strength and stability
The strength and stability of the material directly affect the service life and stability of the outdoor wall lamp. Aluminum alloys usually have high strength and stability, can withstand external shocks and vibrations, and are not easily deformed or damaged. Stainless steel also has good strength and stability, but you need to pay attention to choosing 304 or 316 stainless steel to improve corrosion resistance. Although cast iron has high strength, it is prone to fatigue cracks and corrosion during long-term use, so it requires regular maintenance and upkeep.
Beautiful appearance and decorative effect
The material selection of outdoor wall lights directly affects its appearance and decorative effect. Aluminum alloy is often used in modern-style outdoor wall lights, which have a simple, modern appearance and are suitable for most architectural styles. Stainless steel is often used in high-end villas or modern buildings. Its metallic texture and gloss can enhance the overall texture of the building. Cast iron is often used in traditional or classical style outdoor wall lamps, and its gorgeous shape and texture can add to the building's historical feel and cultural atmosphere.
Weight and ease of installation
The material choice of an outdoor wall light will also affect its weight and ease of installation. Aluminum alloys are generally lighter, easier to handle and install, and are suitable for a variety of wall types. Stainless steel is relatively heavy, so the load-bearing capacity and fixation method of its installation need to be considered. Cast iron is heavier and requires a stronger fixed structure, so it is suitable for solid walls such as concrete walls.
