Cold Cathode lighting is the most commonly used form of case lighting on the market. Advancing on the standard 12V neon, cold cathode lamps operate by use on a power inverter, which converts the standard 12V input to hundreds of volts of power. This is done by minimizing the amperage, via the inverter unit (included with the kit). The end effect is an intensely bright and thin tube, the most popular form of lighting today. This product is great for adding lighting to your computer. Believe it or not many car enthusiasts use these same devices to tweak their cars as well. Try it! You'll like it! Kit contains all the necessary hardware for mounting and powering the cold cathode.
