Viqua / Sterilight - Replacement Lamp - S463RL
The UV light was fine, it is not the first time that I bought lights from you. I have also bought the glass sleeves for the water system from you. My only complaint is that the O rings that come with the sleeves are not wide enough for my system. The small O� rings are for systems made after 2014. I have had to use plumber's tape. - James M.

The place to buy from!
This is the ONLY place to buy your Viqua bulbs from. I shopped around. Great communication and pricing FAST shipping. They even UNDERSOLD me as I was asking for a quantity of bulbs that I would have to store PAST warranty date. They recommended I not do that (smart advice). So, buy from them on HONESTLY alone ( great communication, price and fast shipping). They are my go-to people for Viqua bulbs! - Ranger

Sterilight S740RL-HO Lamp Customer Questions & Answers

Question:	Does this include the rubber o-rings needed for installation?
Answer(s):	Yes, the o-rings are included when you purchase a lamp. By HomePlus Water on Jul 11, 2023

It is critical that only genuine Viqua brand original equipment lamps be used in your system. It has come to our attention that a number of Chinese manufacturers are making knock-off replica UV lamps. While they may physically fit in a Viqua system, they are NOT compatible. Testing of a wide range of these lamps has shown that many do not provide a safe UV dose or offer protection for the stated lamp life, and in some cases have even caused the failure of the ballast/controller and melting of the lamp harness.
