This in May 2023 and installed 5/17/23. The bulb burned out June 27. I do not recommend trying from again. ### ⭐⭐⭐⭐⭐ Excellent Service *by B***X on September 22, 2023* Had a problem with bulb that was bought and immediately got a replacement. Excellent customer service. ### ⭐ Two Bulbs ordered. Both did not work - Zero light output. *by D***. on March 6, 2022* Two Bulbs ordered. Both did not work - Zero light output. Sometimes Mercury lamps take time to warm-up. I waited 30 minutes for each bulb, but no light output. I had to go to the OEM for a replacement bulb that worked. ## Frequently Bought Together - Caprock S410RL-HO STERILIGHT Replacement U-C GERMICIDAL LAMP for SP-410 SPV-410 SPV-8 VH-410 BUT NOT Made by STERILIGHT - Pentair Pentek DGD-5005-20 Big Blue Water Filter, 20-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 20" x 4.5", 5 Micron, Pack of 1, White - US Water Filters S200RL-HO Replacement UV Lamp | Fits the VIQUA VH200, SP200-HO, SC-200, & SPV-3.5 Series UV Systems | Made in the USA --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/79011973-caprock-s410rl-ho-sterilight-replacement-u-c-germicidal-lamp-sp](https://www.desertcart.pl/products/79011973-caprock-s410rl-ho-sterilight-replacement-u-c-germicidal-lamp-sp) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-22*
