Lumière Rouge is designed with longevity and durability in mind. While the device itself does not have an expiration date, its optimal performance and effectiveness can typically be maintained for several years with proper care and regular maintenance. However, like all electronic devices, the lifespan can vary based on usage patterns and care. We recommend following the care instructions provided with your device to ensure you get the most out of your Lumière Rouge. Periodic updates and calibrations may be necessary to keep the device functioning at its best, especially if used frequently.
