And once we find the ballast we can light one of them... Wonder

That's a nice little collection of the range you have there. I have a couple of the 60W lamps.

Yes, they are all from Philips. Second generation to be exact. Really good lamps there!

We only have a ballast for the 60W one at the moment, though.

Those are robust lamps (I experimented a lot with those), you can run them a bit off specs on standard ballasts (e.g. 45 W lamp on 50 W gear, 60 W lamp on 70 W gear, 90 W lamp on 100W gear, etc.). If you use standard electromagnetic ballasts, then you can run the lamp properly by adjusting the input voltage using a variac until the lamp's rms current matches its specification (good enough for testing purposes).

By the way, they were made at the Philips HID lamp plant in Turnhout, not by Sylvania Tienen.
