The LUMINOR RQ-470 is a replacement quartz sleeve for the LUMINOR BLACKCOMB 4.1 LB4-061, 5.1 LB5-061, 6.1 LB6-061 UV Systems. The quartz sleeve keeps the UV lamp from shorting out and maintains the lamp's ideal operating temperature. 

Mineral build-up hinders the lamp's effectiveness and should be cleaned regularly. UV quartz sleeves should be replaced when they are chipped, cracked, or remain discolored even after cleaning. 

Warranty: Full one-year, no-hassle replacement warranty protection.
