This is a self-ballasted mercury lamp. The picture here shows only the ballasting filament lights and the arctube still cold. It should have a daylight like color when hot, as it don't have a phosphor.

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 lives in Israel, which is a 230-240V, 50hz country.

you're right . the bulb was not yet hot at all. It is very bright . it does not appear to have phosphorus. I have another specimen that seems to have the same material that covers fluorescent tubes.

The phosphor in mercury lamps is to add red light to the mercury spectrum, to improve the color rendering and to lower the color temperature of the lamp.

After turning on the lamp, you need to wait 2 min for the color to change, and you can't light it after turning on for 2 min: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-157037

It is correct, the lamp if it was on does not turn on until it cools down. Another detail that you comment is that in osram bulbs it is in filament in the middle of the tube. which heats up better. I have another one that has it on top, therefore I think it should only be turned on with the base raised

The lamps with the filament on top, needs to be burned with the base up to heat better.
