Alternative Studio Command 700 Bulb

I Wonder if anyone can help.Need some info for Studio Command 700 Bulbs. I am hoping to find out if The Osram HSR 700 Lamp or the Osram HSR 700/60 is an alternative for the Philips MSR 700 and The Philips MSR 700/2 as Philips are not manufacturing these anymore, I did notice in the Specs for both lamps that the Osram Bulbs have a Lamp Voltage of 72V (is this Ignition Supply Voltage ? ) and the Philips Have an Ignition Supply Voltage (Min) of 720V

Thank You
