Are the two lamps connected to two ballast or to a single ballast in parallel?

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 hope that LED won't replace all forms of other light

I didn't look at those fixtures at night when they were working so I don't know.

Interesting set-up! I've never seen such a luminaire configuration in France before, and I've already been in Grenoble in the past (haven't looked up at the right place though). Given the rather long aspect ratio of these lamps I'd say they are most likely rated at 250 W. I'd wager that both lamps are operated individually and one is switched off late at night in order to save energy... this was a common scheme in certain parts of France some decades ago and I can imagine that some of those installations still remain to this day, probably with only one lamp burning 100 % of the time.
