What is the average life expectancy of an interior light fixture?
Sunday, May 24, 2020
You can expect an interior light fixture to last 40 to 50 years, with an average of 45 years. A light fixture is referred to in the building codes as a “luminaire,” and can go bad due to corrosion, obsolescence, a short circuit that fries the wiring, or accidental damage. Many get replaced before the end of their functional life, as part of updating a home to match current styles.
