Luminor RL-420 UV Replacement Lamp for LB4-Z1, LB4-Z12

This UV lamp is the replacement lamp and key for LUMINOR BLACKCOMB LB4-Z1, LB4-Z12, LB5-Z1, and LB5-Z12 Model UV water treatment systems. 

The RL-420 is an authentic LUMINOR lamp and has a 9,000-hour lamp life. The UV-C light being emitted will weaken with time, so once a lamp reaches 9,000 hours (or every 12 months), it is important to replace the bulb promptly.

Why using a genuine LUMINOR lamp is important: LUMINOR UV systems and lamps are tested and certified as a complete unit. Using an authentic LUMINOR lamp ensures proper system performance. Using non-LUMINOR lamps voids all UV system certifications and may compromise your warranty should an issue arise.
