Here in Brazil able to think that it is a MH 70w. Cool these mini MVs, is that in a ballast MH 35w or XMH, does it work? Or do you need to remove the igniter?

Igniter is not needed with these standard MV bulbs.
They can run on 58W T8 ballasts with no problem.

No more cheapy crappy Chinese junk, please.

Yes I have seen this, although I keep
thinking, is there a risk in using external ignitor? As for example damaging the starting electrode,probably the idea of ​​using fluorescent ballast should be very useful, even more so in Brazil that the input voltage is 220v in most MV ballasts, although in the southeast region of Brazil it uses more 127v

Using an ignitor with a mercury lamp, can damage the starting probe and can also cause arcing in the outerbulb.

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 lives in Israel, which is a 230-240V, 50hz country.

The igniter won’t do much damage to the MV bulb during cold-starts, the problem occurs when you attempt to do a hot restrike.
The ignition voltage of the arc tube is higher than the breakdown voltage in the outer bulb when hot, so the arc will strike outside the arc tube and causes damage.

No more cheapy crappy Chinese junk, please.
