It is an authentic Luminor part, not a compatible aftermarket substitute, so it keeps your system performing the way it was originally tested and certified.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe sleeve is an open-style quartz tube that surrounds the UV lamp, letting UV-C light pass through to the water while keeping the lamp itself dry and at the right operating temperature. Luminor recommends replacing it every 24 months, or sooner if it's visibly scaled, cloudy, scratched, or pitted.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhy the sleeve needs replacing, even though it's not a wear part like the lamp\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eUnlike the lamp, the quartz sleeve doesn't burn out on a fixed schedule. Instead, mineral scale and staining build up on its surface over time, gradually blocking UV-C transmission even if the lamp inside is brand new. Annual cleaning with a scale remover can restore clarity for a while, but once a sleeve is scratched, pitted, or stays cloudy after cleaning, it needs to be replaced rather than cleaned again.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhy a genuine Luminor sleeve matters\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eLuminor tests and certifies its UV systems as a complete unit: lamp, chamber, and sleeve together. An authentic RQ-500 keeps your system's UV dose where it was certified. A non-Luminor sleeve can differ in wall thickness or quartz quality, which changes how much UV-C actually reaches the water, and can affect your warranty coverage if a problem comes up later.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFits these Luminor Rainier systems\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eLR5-355\u003c\/li\u003e\n\u003cli\u003eLR6-355\u003c\/li\u003e\n\u003cli\u003eLR5-355-50 (low-UVT crossover)\u003c\/li\u003e\n\u003cli\u003eLR6-355-50 (low-UVT crossover)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eAll four models above pair the RQ-500 sleeve with the RL-500A lamp.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eComplete your replacement\u003c\/strong\u003e The RQ-500 is the sleeve only.
