My understanding is that the larger the diameter of the tube the more current is needed. The longer the tube the higher the voltage needed. The bar light I have has two different diameter tubes in series. I've cut the wire that connects the two different diameter tubes and plan to use two...

Still unanswered though is whether AC is better than DC. The theory I understand is that electrons are emitted from one end and traverse through the tube causing the gas inside to emit photons. An AC current will alternate flow of electrons from one side to the other whereas DC will cause...

I've a question about current. According to what I've read, the current must be limited in order to not burn out the tubes. Will going from 20mA to 30mA cause the tubes to have a much lower lifespan? Also according to my understanding the AC transformers for neon lights have a shunt in them to...

Update on retrofitting my Neutron Star sign and getting bar sign to work. The 7.5kv DC power supply came in and powers both parts of the Neutron Star sign just fine. But only starts the bar sign, which has quite a longer length set of tubes as well as part of the tubes are smaller diameter...

I presume you are asking about the bar sign tubes because I included a picture of the pinball sign all lit up nicely. When the bar sign lights up, it lights up quick and bright, all the tubes are lit, then they all flicker at the same time, After adding up the linear feet I chose a power supply...

Thanks for the advice on matching numbers and amazon. Maybe someone can answer my original questions. I have another neon bar sign that I hooked the franceformers up to. It flicks on but is unable to keep going, I suspect that the voltage is high enough to light it up but the current is not high...

Yes, the transformers input is AC 120V. I'm not talking about that though. The question is about the output being 7500V AC, or can a replacement DC 7500V 30ma power supply which are much lighter and only about $40 on amazon. Recommendations welcome as well as any info to correct any...

I have what i think is a basic question but i've searched and not been able to find an answer. i recently acquired a neon sign that was in storage for a long time. It came with 2 7.5kv 20ma AC output Franceformers. These transformers are loose and not mounted in any enclosure as well as fairly...
