The Death Of A Fluorescent Bulb (vid 34)

For the 34th in my "Death Of A Fluorescent" series I've got a F2T12 to finish off.
This one gave a good show, and it just kept going & going...
It ran it on multiple short sessions (anywhere from 1 to 15+ minutes), since it would
flicker/snake-of-lightning/orange-end-glow/etc, then stabilize. Letting it cool a bit
would make it 'active' again.
Even from that, allot of video was cut out using just the best parts, (and needing to
keep it under the 15-minute limit.) Had everything been used, it would have made for
well over a hour's worth of boring video.
And yes it was dimming the 2nd bulb on the ballast.
Ballast used is a Osram 2xF32T8 instant start electronic.
0:00 Part 01 (orange glow in failed end)
1:04 Part 02 (more orange glow)
2:04 Part 03 (2nd end filament starts to fail)
3:50 Part 04 (blinking orange in 2nd end)
7:49 Part 05 (dimmer blinking orange)
8:45 Part 06 (tube flickering/snakes)
9:31 Part 07 (more flickering)
10:22 Part 08 (flickering/some end glow)
11:13 Part 09 (going dim/snakes/end glow on both)
12:26 Part 10 (going dim/snakes/end glow on both)
13:28 Part 11 (final run.. more going dim & flickering)
14:22 Part 12 (won't come on, vacuum lost after turning off last run)

When a fluorescent tube becomes a rectifier diode

[@Placeholder71]

What causes that almost string-like action to happen inside the lamp?

Siempre la pasion mia estos tubos parpadeantes el led aburrido por fin alguien tubo en cuenta estas hermosas lamparas

[@Imakeelectronicchaos]

Wow, I’m surprised that didn’t burn the plastic caps that the bulb slots into, I saw another video where someone had a EOL bulb that went like this and the ends got so hot it melted the bulb sockets

[@Charlie-B-Barkin]

that bulb must have got so hot

[@coalthedergsune]

I wonder if the ballast is what causes the orange pulsing in the EOL end? maybe trying to adjust for the varying power draw?

R.I.P 😢
