“A lamp 12v/80mA has the same characteristics even bought from beoparts or elsewhere.”

True.

But quality could be the difference.
From Asia you can often buy very cheap lamps meant for use in plastic toys.
They typically have a rated lifespan of, perhaps, 200 hours (and tolerances not worth mentioning).
You will often find these listed on Ebay and similar places for next to nothing.
If you go for this quality it would be a good idea, as suggested in the linked thread, to buy
lots of ten or more and, if you use your Beomaster on a regular basis, you will also
develop good lamp replacement skills.

Lamps from Beoparts-shop often have an expected lifespan of 2000 hours, some even 5-8000 hours.
Some lamps sold there are actually custom produced.

And the resistor will run warm.
That’s Ohms law.
