The answer to 'how long does light fixture last' is that the average lifespan of a light fixture is 8-12 years, depending on the type and quality of the fixture. Higher-quality fixtures made with durable materials like metal and glass tend to last longer than lower-quality plastic fixtures. Additionally, proper installation, maintenance, and usage habits can significantly impact a light fixture's longevity.
For example, recessed lights and flush-mounted ceiling fixtures generally last longer than hanging pendant lights or wall sconces, as they are less susceptible to damage from bumps and impacts. Proper cleaning and replacement of light bulbs as needed can also extend the life of a fixture. If a light fixture starts flickering, making strange noises, or the light output diminishes, it may be time to consider replacing the entire fixture.
