Purely Products PUVH2309 9-Watt UV-C Germicidal Ultraviolet Replacement Bulb

by Purely Products

Product Description

From the Manufacturer

UV-C light is germicidal i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV-C light causes damage to the nucleic acid of micro-organisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.

Product Description

Purely UV-C Replacement Bulbs G23 BasePurely UV-C Replacement bulbs offer a much higher concentration of ultraviolet light than even the sun, making them highly effective as a cleaning and purifying agent for pond and aquarium pumps and clarifiers.What is UV and How Does it Work?UV light is germicidal - i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.What are the Beneficial uses of UV Light?Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance.How do Ultraviolet Water Purifiers Work?UV water purification units contain one or more germicidal ultraviolet lamps. The germicidal lamp is a short wave low pressure mercury vapor tube that produces ultraviolet wavelengths that are lethal to micro-organisms. This wavelength is in the region of maximum germicidal effectiveness and is highly lethal to virus, bacteria and mold spores. Therefore, the water or air that passes through the chamber is exposed to the germicidal UV light and the genetic material of the micro-organism is deactivated, which prevents them from reproducing and renders them harmless.Reference Tool for choosing the correct UV-C Replacement Bulb:Match your existing bulb to one of the bases.Match the wattage or length of your bulb. Some bulbs have a different length for the same wattage -- so be sure to match both watts and length.H-Series:The Purely UV L-Series carries the industry standard 2G11, G23 and GX23 base.The "H" is for the H-look with parallel glass connected by

I bought 2 of these for my Coralife TurboTwist x3 pond sterilizer, correct fitting, correct wattage. Neither bulb would light, so I assumed it was the fault of the unit which was under warranty. Coralife sent me a replacement ballast but neither bulb would light in the new unit either. I went out and paid $30some for a coralife brand replacement bulb and sure enough it lit right up. Not sure how they've done it, but you can't use these cheap bulbs in Coralife UV sterilizers, so don't waste your time like I did.

Got this product in the mail today.

When I installed the bulb, the first strike was a little difficult, the ballast had to try for about 15 seconds before the bulb would stay lit, subsequent strikes have been much faster and the bulb works as intended.

I use this in a Secure Air SA1200.

1.0 out of 5 stars Doesn't work with turbo twist 3x, May 18, 2011

The purely products website lists this bulb as being compatible with the Coralife Turbo Twist 3x..... well it's not. The size and socket are correct but when you plug it in and power it up it never turns on. I have tried 2 of these the first one I sent back for a replacement, thinking it must just be defective, well the replacement didn't work either.
