The answer to 'when to replace recessed lighting' is that recessed lighting fixtures typically last 20-30 years with proper maintenance. However, there are several signs that it may be time to replace your recessed lights, including:
Flickering or dimming lights: This can indicate a problem with the electrical components or bulb. Replacing the bulb may fix the issue, but if the problem persists, it's likely time to replace the entire fixture.
Outdated technology: Older recessed lights may use less energy-efficient bulb types, like incandescent or halogen. Upgrading to LED recessed lights can significantly improve energy efficiency and reduce your utility bills.
Damage or wear: If the recessed light housing, trim, or other components are cracked, corroded, or otherwise damaged, it's best to replace the entire fixture to ensure proper function and safety.
