Ah yes it is quite possible!

it can also have the function of creating a phase shift (if condo in series) in order to avoid the stroboscopic effect which can be dangerous with rotating machines. In general it is on duets and it is only on one in two hits, but nothing prevents to do it punctually on singles.

Ah yes not stupid as a technique but no this one was in parallel ...

if in parallel then the goal is simply to straighten the cosine phi

Yes the explanation of Macro suits me too ... the 2 phenomena are certainly linked.

I still dismantled a few dozen neon lights in my life and it was the first time I saw this.

In industry it also seems to me that it is to reduce reactive energy billing ... And there is also the story of the stroboscopic effect on rotating machines ... that I had forgotten ...

The only thing safe in the future. It is that there may chance that it conforms to our expectations ...

Yes macro so the cos phi ...

Well I think we have covered the question! Thank you zamis! So I'm going to test with and without the condo during reassembly ... "to see" ..

Electromagnetic ballasts are exceeded, cos phi 0.5, heat up (joule losses), strobe effects and eye fatigue. The capacitor is there to bring the cos phi back to 0.9, nothing else.

Electronic ballasts have replaced them for a long time. They no longer require a starter or capacitor, operate from 25 to 60 khz, so no more flickering.

I just installed 36W LED neon lights ...

Please note that this does not install "like that" to replace the old ones: you have to change the electrical wiring but you just have to bypass the transformer and connect 1 Phase 1 Neutral at each end

I had about 1 hour of rewiring (it's always a bit painful to work on the ceiling), I left the transformers in the frame ... no interest in dismantling them ... especially since they are tired for the 2 survivors.

Well with 2 36W LED 4000K neons I have more brightness than 3 classic 36W neon lights ... and especially instant lighting and no noise ...

The actual lifespan remains to be seen ... the existing installation dated from the 80s ...

I am preparing a detailed article with pictures of the wiring soon ...

Normally it is "36 W substitute", the power consumed is 14.5 W, duration 30000 hours advertised instead of 20000 for a neon.

Is it that kind? https://www.lampesdirect.fr/philips-cor ... stitut-36w
