How do you wire a Dual Blue Cold Cathode Light Kit that is made for computers, to just "simply" plug directly to a wall outlet.

Here is a website that shows the product I am talking about.

12in Dual Blue Cold Cathode Kit (http://www.xoxide.com/bluecathode.html).

I am not using the light for a computer system. Thanks for your help!

You need to get a wall adapter of 3.7 W/12V or greater than about 308 mA to run the lamp. If using multiple lamps. Multiply the 0.308 * n to get Amps. Multiply 1000 to get mA or milliamps.
