Overconsumption of fluorescent tubes on ignition

[delnoram]

JThe do not know, it is necessary that I look at it more closely, not enough backwards with the new oscillo.

0,49 A (so, about 115 watts), but for how long? This is what is important.

I was talking about mine

You might as well do 2 series of measurements! History to clarify this affair!

ps: elephant, he said the duration: less than a second ... provided that this is not a measurement error ...

[delnoram]

Say a fraction of a second

I had to do at least 50 tests, the highest was 0.49A, but the others varied from 0.10A to 0.33 delicate to say more precisely as the display is short.

Good evening,

I'm relaunching this post because I didn't understand everything !!
So how long does it take to leave a fluorecent tube on to "dampen" fuel consumption on ignition?
Thanks for the reply

[delnoram]

no overconsumption on ignition, so there is nothing to amortize

[Christophe]

Very little ... we speak above of a peak of less than a fraction of a second which does not exceed three times the normal consumption.
And nothing says that it is not a measurement error.

Yesterday I tested on a 12V compact fluorescent (this model here: https://www.econologie.com/shop/ampoule- ... p-121.html ) connected to a laboratory power supply which provides direct voltage and amperage, there was strictly NO overcurrent at start-up!

So this overconsumption smacks of legend ...

On the other hand, a TL wears out (as on certain compact fluorescent lamps) with ON / OFF too frequent. That alone deserves that we do not make ON / OFF of less than say, 30 seconds ...

By cons TL wears (as on some compact fluorescent)

Of course, I have in my hallway a compact fluorescent "studied for frequent lighting", but it is expensive: 20 euros at my wholesaler.

Incandescent lamps also do not like reciprocating cycles and especially not quartz-iodine lamps because it disturbs the filament recharging cycle.

elephant, every Megaman INGENIUM bulbs are insensitive to ON / OFF, it's not first prize (= big shit anyway) but they don't all cost 20 euros, far from it: economic and LED bulbs

Thank you very much for the answers because indeed there is a sacred legend on the subject !!!
