UV light (Cold catode) = bad?

post #1 of 21
Thread Starter 
I was just wondering if its bad to use Cold cathode lights when you have a watercooling setup?

reacting with the water and whatnot?

Reacting with water? If anything, they could kill any bacteria in your loop. Here. But I doubt the ones in your PC would do such job.

The sun sends out UV Light, which the Algae in the sea need to survive

I just bought 2 large filter/pumps for an aquarium we ordered. They have, built in, UV-C sterilizers that kill the algae and other harmful organisms. I dont know if they are remotely the same, but they are both UV.

I have the T-Virus reservoir by Frozen-Q, with a built in UV cathode in the center. I have never had any problems, and never used any biocides like PTnuke. Just True silver fittings and a killcoil.

Of course. But do understand there is not just one type of UV Light. There is three UV types. Here. Algae is like a plant, they use the sun's energy to photosynthesize.

Okay, thanks guys. Just wanted to be sure

Can anyone tell me if These Cold Cathodes is sent with all I need? Starting module = inverter?

Those aren't UV lights. Those are Red CCFL's. But I do believe that the starting module would be the inverter.

They are lights atleast

I use 2x large UV lights in the WC setup, as well as 1x UV diode in each of my GPU blocks... as far as your concern with plant growth/algae in the loop fed by UV light... well... hard to say really.

Like any light the color such as UV, is simply shifted into the ultra violet wavelength, and the red CCFL is in the red spectrum, which is (off the top of my head) on the ass other side of the wavelength spectrum. To know weather or not some critters will use that light, take the UV stick somewhere in your home where some stuff is growing (bathrooms are good for this) and if it glows under the light, it does not use it, and if it is black under the light, it does. It can only "use" what it absorbs, but in answer to your question... I doubt it makes much difference one way or the other...

Now clear tube, out in the sunlight... is like a greenhouse for critters... for what its worth...

UV-c is the dangerous wavelength, that's the one that causes sunburn and kills algae, most CCFL lamps will be designed to block it, so all the light you'll get is in the UV-a and UV-b wavelengths, which will do very little to sterilise your loop.
