I made a mistake in my comment, I hoped that the dim stage in the 2x54W T5 HO fixture at the low floor of my hostel, isn't the reason why the Osram lamps ends blackens so fast.

I think that the dim stage of rapid-start ballast (Electronic or magnetic), is when the lamp runs with cold cathodes before the electrodes heated to thermionic emission. It also exists in the British SRS ballasts, but looks different.
