I'm interested in building my own custom inverter to power several 12 inch cold cathode lights to put in my computer case. I can't seem to find any info on the amount of current or voltage these lights need to function. Could someone point me in the right direction? ops: I did a search for inverters on the forums and found a few schematics with a noticeable difference. The inverters I'm used to seeing have what looks like a coil of wire between the transistors, besides the transformer. :?: I'm thinking of powering at most 5 12 inch lights from the 12 volt supply on the computers power supply. Thanks for any info you can give me. :P

 

For cold-cathode light tubes need high voltage AC (about 2...3kV), the color depend from encapsulated gas (e.g. neon give red light).
The transformer must be current-limiter type (with magnetic shunt).
I think, the fluorescent-tube inverter with higher output voltage also work.
