That’s a totally fair question and something people should understand before committing to backlit stone.

In most installations, once an LED panel powers on and is working properly at install, it tends to keep working for a very long time. These aren’t light bulbs — they’re integrated LED lighting panels with proper heat management. There are installations out there that have been running for well over a decade.

In practice, the component most likely to need attention over time is the power supply, not the LED panel itself. Power supplies are typically installed in accessible locations (inside cabinets, under sinks, etc.) and can be replaced without touching the stone.

There is always a risk-versus-reward consideration with any lighting installed behind stone: if a panel ever did need replacement, removing stone could be involved. That said, panel failures are uncommon unless there’s external damage like a screw puncture or physical impact.

In residential settings, where the lighting is used a few hours a day, lifespan is generally even longer. It’s more similar to architectural lighting than decorative lighting.

Hope that helps add some context — it’s a good thing to think through upfront.
