Gidday there Eli!,
I'll see what I can dig up for you.
They're common around these parts.
A MBFU (Blended High Pressure) lamp requires only a starting ballast.
The only starting equipment (a starting resistor and an arc contact) is held within the arc-tube of the lamp envelope.
Provided you have the correct ballast, it should start and run as per normal.
All the ballast does is control the current drawn by the lamp during starting and running of the lamp.
