Luminor RL-420 Genuine OEM UV Replacement Lamp | Free Ship


Luminor RL-420 UV Replacement Lamp for all Rack-mount Standard-output systems LB4/5-Z1, LB4/5-Z2, LB4/5-Z12

This Genuine LUMINOR BLACKCOMB RL-420 UV Lamp is the replacement lamp and key for all rack-mount standard-output Luminor Blackcomb systems LB4/5-Z1, LB4/5-Z2, and LB4/5-Z12. The UV lamp is the key component of your UV system as the light destroys waterborne bacteria as they pass through the UV rays to protect your family. Replacing your UV lamp on schedule ensures you get the cleanest, bacteria free water your system can produce.

This RL-420 is an authentic LUMINOR lamp and has a 9,000-hour lamp life. The UV light produced will diminish with time, so once your lamp reaches 9,000 hours (or every 375 days), it’s mandatory to replace the lamp.

Using an authentic LUMINOR lamp ensures proper system performance and water disinfection, providing you with confidence in knowing your family's water is safe.
