Sylvania 865 18W neon trying to turn on, eventually creating condensation inside the tube. For now, it no longer lights up, but if it starts working again, I will let you know.
It is defective, I have seen tubes turning on at extremely low temperatures, in freezers for example, and they turn on dimly and purple due to the mercury not being vaporized, but they never fail to turn on
Yes, I’ve also seen tubes in freezers, but this neon light was in an environment that was frighteningly humid and cold. In fact, condensation formed inside, which caused the tube to short circuit I think
@@mrlux0716 Strangely, I tried measuring the filaments with the multimeter, and the filaments work. It's just that after it turned off, I heard a noise like when you pour water on something hot. I hope the condensation inside didn't get into the tungsten and damage it. The tube was new.
@@cla829 the filament always has a resistance even if it is bad, what happens is that it loses the thermo ionic materials, what possibly happened is that if the tube is new it probably has some problem with the internal gases
@@cla829 Here in Brazil there is a company that recycles fluorescents, and it has several bins spread around the city. On their website, by entering my address, I can see the bins that are here in the city, and once a week I go to see what tubes there are.
Oui, selon moi, l'humidité est entrée dans le tube parce qu'il s'est mouillé et gelé, et quand il a été allumé, ça commençait à provoquer un choc thermique, disons. Donc l'humidité est entrée et est allée dans le tungstène. D'ailleurs, ensuite, pendant que je le séchais avec le sèche-cheveux, il y avait des taches qui se déplaçaient, on aurait dit de l'eau.
