RLQ-420 Replacement UV Lamp/Sleeve Combo | Fits the USWF 4CR1 UV System | Made in the USA, US Water Filters

Genuine US Water Filters replacement Lamp/Sleeve for the USWF-4CR1 UV system. USWF lamps and sleeves are backed by a one-year, no-hassle warranty. The high-performance UV lamp boasts a 9,000 hour lamp life, which means low hassle and maintenance for 12 months between lamp changes. After 9,000 hours the UV light weakens and isn't strong enough to properly treat your water. Replacing your lamp annually ensures optimal system performance. The quartz sleeve is an important part of the UV water treatment system. It protects the UV lamp from coming in contact with the water while allowing the UV light to penetrate the water. Minerals from the water will build up on the sleeve over time causing the sleeve to become cloudy not allowing the UV light to penetrate the water as effectively. Once the mineral layer on the quartz sleeve cannot be removed via cleaning, or the sleeve cracks or breaks it's time to get a replacement. USWF-RLQ-420 includes the USWF-RL420 lamp, USWF-RQ420 sleeve, and 2 o-rings to ensure you can replace the o-rings after every cleaning and lamp replacement. Safety Note: NEVER look directly at the UV lamp when it is powered on. Follow the instructions carefully to avoid injury to eyes and skin.
