Google "HBO-100" and find the Osram site. Osram has been the maker of high-pressure mercury lamp. They provide data sheets for the family of HBO lamps, including the HBO-200. I saw in the data table that the nominal voltage and wattage are 57 and 200, respectively. So the current would be ~3.5A.
Please note that the power supply for such lamps is a dedicated device, since an initial ignition of the lamp is required.

Thanks.
That was stupid of me, I have found the voltage on the Oram site, but somehow it did not come into my mind to calculate current from the power rating.
I have dedicated PSU for it, but it has 6 steps current selector between 3.3 and 5A.
Best.
Petro.
