 So today I'll be doing a quick unboxing of a popular PC modding item and that is a dual 12 inch cold cathode kit. So basically what this is, it's a way of lighting up your PC. The particular one I have here today is a UV cold cathode kit. So you can get it in a variety of colors including blue, red, green, purple, yellow, white and UV. Now the difference between purple and UV is purple is actually intended to throw purple light into your case. So your whole PC will glow out purple. Whereas a UV cathode kit is more designed to allow UV reactive things inside your case to glow whatever color they happen to be. So I mean if you look directly at a UV cathode it will look purple but the main purpose of it is to be a black light. So if you're looking for something that will actually light up your case you're looking for a color other than this one. So why don't I explain everything that comes with it. First of all you've got five pieces of velcro, four small ones and one big one. The four small ones are for using at either end of the cathodes and then mounting them to something in your case so you stick them on. Really the velcro that's included isn't great quality. I'd recommend picking up some double sided tape or some industrial velcro from your hardware store if you really want them to stay put. However the big one's usually okay and you use that to mount the inverter. Now what an inverter is, is it's a device for taking the 12 volt power from your power supply and converting that into something that these cathodes can use. Because these run on AC power which is more like the power that you'd find in your walls. So basically you're taking your computer power supply, you're turning AC into DC, then you're taking that DC power, putting it into here and putting it back into AC. It seems very round about but it's the best way to run cathodes in your PC. So these are the cathodes themselves, they're 12 inches long or 30 centimeters long. They come with little white wires attached to them. I've experimented with ways of making these look nicer. You can sleeve them quite easily so that's a really easy way to make them look better. But you can't really lengthen them very much because what tends to happen is the one that you try to splice more wire into will be more dim. So it's very strange, it shouldn't be that way but it is. Anyway I have another kit on hand that I've already got set up here and I'm just going to show you what it looks like. So that is a UV kit. You can see it doesn't throw up a whole lot of light compared to the other ones. But you do have the advantage as I showed in my ModSmart SATA cable unboxing of making other stuff glow. So that effect is very cool. Thank you for checking out my unboxing of the Logisys 12 inch cold cathodes.
