12" Dual Cold Cathode Kit, 3.0mm Tube Diameter, 680V Output Voltage, Green

These cold-cathode green colored tubes are made for accent lighting for a PC or even a car. I used them to test some HV power supplies I was building. With the included driver circuit these are bright!

not work at all! to my computer did not work I think anything that came with problem.

Bright and wonderful color to it. I use it to light up a bit of grating in the front of my computer (see shinobi window cases) My case looks way more interesting with these, they're easy to hook up with plenty of wire length. Everything I was looking for at a wonderful price!

They work real good, nearly too good. They are super bright, and are overtaking all the other fan colors.I may unlug one. After installing, I was mad for a minute. After plugging them in, I got nothing. But, then tried the switch-boom green! Do yourself a favor and run to Radio Shack and spend $5.00 on some more Velcro. You'll need more then they provide. These are well worth the money.

Pros--It's definetly bright enough and looks super awesome-Super easy to setup-No tempeture change in case what so ever.-Nice PriceCons--The velcro that comes with it isnt the best, the sticky side doesnt stick super well to my case (I have it attached to metal)-One of the two lights stopped lighting up within the first 12 hours of use, so only having 1 is sort of a bummer.Overall it looks great, I'm just pretty upset that one of the lights just stopped working so soon. I guess you get what you pay for!

The hardware was kind of clunky, and the wires weren't quite long enough to give me the flexibility I wanted (I'd need 3 more inches of wire to put the lights in opposite corners of my big Antec cabinet), but the lights work just fine. The on-off switch does exactly what it's supposed to, and the lights go out when the PC goes to sleep or shuts down (Windows 8.1)I say "just fine," but honestly, the lights are BRIGHT. The whole corner of the room has an alien green glow to it when the PC is on and the room lights are out. This, of course, is exactly what I wanted...The Velcro was almost useless, however. Even after carefully cleaning the attach points, the adhesive/cabinet bond was weaker than the Velcro bond. I used kneaded eraser bits to attach the lights instead. If you've got your own mounting solution, these will be fine.

horrible product. ive never bought a cold cathod item before. but im sure when it lights up the whole thing is supposed to light up not just half. wondering if its just damaged by coming in the mail or i just got a defective item. oh well, next time ill go with leds

1 tube went out within the first few days
