The answer to 'how long does lighting installation last' is that properly installed lighting fixtures can last for many years, often 10-20 years or more with proper maintenance. The longevity of lighting installation depends on several factors, including the quality of the fixtures, the wiring and electrical work, and how well the installation is maintained over time.
High-quality lighting fixtures made with durable materials like metal and glass can withstand years of use, while cheaper fixtures may only last 5-10 years before needing replacement. Proper electrical work is also crucial, as faulty wiring or improper installation can lead to safety issues and shorter lifespan. Regular cleaning and maintenance, such as replacing bulbs and addressing any issues, can help maximize the longevity of your lighting installation.
