My F20T12 hasn’t had any black markings on the tube being used for 2 years. But it made a decision to do that.
After turning on it on it sputtered then that black mark came
But why does it disappear during warming up

This looks like mercury evaporation rather than electrode sputtering.

I"m don't speak english well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I hope that LED won't replace all forms of other light

It's weird how it comes up immediately after striking the lamp

I had the same thing happen to some 13w PL lamps and my LOA F15T8 lamp.

My favorite lamps are Compact Fluorescent (PL) fluorescent, High Pressure Sodium (Eliptical) high pressure sodium, Low Pressure Sodium low pressure sodium and Mercury Vapor Lamp mercury vapor.

Like Dor said, if it goes away after warming up, it's mercury condensation.

I like my lamps thick, my ballasts heavy, and my fixtures tough.
