One of the bulbs I want to use for my project to rebuild the Narva igniter installation and the Electrofar Ballast both from a 1983 installation.

Tend to fail after some hours of use. Our ones were creating cracks around the base, detaching the bulb and causing failure due to oxidizing of the burners leads.

What do you think about Narva E27 / 50W / 85V? Are they ok?

Don’t know about these as we don’t have them here. In our council we use only Philips lamps.
