John Francis from France

Post by John Francis »

Hi . I am an artist currently playing around with light. I found your site while doing a search on power supplies for neon and fluorescent tubes.
I wanted to know if I could get a neon tube to light using a fluorescent light transformer........Have not been able to find an answer ALTHOUGH
I did find a youtube video of someone lighting fluorescent tubes with a transformer for neon!

So!Can I get a neon tube to light using a fluorescent light transformer???
Whether it works properly or not is not an issue as long as it won't start a fire or explode
Thanks in advance for any info!
I would post an image of what I am doing but img dose not want to work

No, you will need a formal neon sign transformer.

Thanks Richard. How come the neon transformer works for fluorescent light?

I am getting interested in anything that glows in a glass tube

There are two common ways of igniting a plasma: putting a ton of voltage into it (neon signs, Cold Cathode fluorescent), and using a glowing hot light bulb filament to thermionically emit electrons, which will ignite the plasma (most fluorescent bulbs).


The voltage to keep a discharge running is much lower than voltage to start it. (100-600V versus 5kV and up)

If you connect a fluorescent tube to a NST, then you just use the filaments at the ends like ordinary cold cathodes.

Guys, please remember, this is a "Introduce yourself" sub-forum. John, I recognize that you seem to only be here to get some HV assistance and that's fine. I have no doubt everyone (myself included) will be happy to assist, but please still follow the rules. Make your formal introduction here, then spend some time reading the HV sub-forum as you will get lots of your questions answered there. Finally, if you still are not able to find something helpful, please post your questions in the HV sub-forum. This is not the place for extended discussion. Cheers!
