Philips ALTO F20T12 on it's last legs

Philips ALTO F20T12 on it's last legs

This lamp almost looks like it's in a partial discharge when it's first turned on. It is really dim.

The cathode broke and it depreciated in lumens very badly.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

Remember that Philips ALTO lamps use less material than other lamps (cathodes included). I even had a GE F24T12 slimline lamp come with a broken cathode (still had vacuum, cathode broken in shipping).

When you say cathode broken, do you mean the electrode filament separation? Or do you mean the filament is no longer
on it's support holders? If the filament is no longer on it's support holders, this lamp will definitely EOL (Based on what I see
in this picture, I'm guessing it's no longer on the support holders.) If the filament only broke apart, I'm surprised it's acting
this way... unless it's on some sort of Trigger Start ballast attempting to fire up in this picture...? lol

Interests
1. Motorcycles, Women, and Lighting (especially fluorescent)
2. Weighting/staying extremely athletic
3. Severe Thunderstorms of all kinds
4. Food and drinks. So gimme them bbq ribs
Yep
Lighting has been a passion of mine since I was born. I consider everyone on LG to be a friend

The filament is seperated. In fact now it is starting to mercury-migrate.

Is it a LPF trigger start ballast running it? Or HPF?

Very common issue with Philips tubes since 2004ish when they went to the Alto II. The filaments don't stay on the support holders and will fall off very easily especially after they have been lit up for the first time and then you jolster the tube.

The more you hate the LED movement, the stronger it becomes.

Yeah I know they suck. I've had 4 F20 Philips Alto tubes, 2 are installed at my grandparents' house and the other 2 the cathodes broke in.
