How it can start without a parallel ignitor, if it have only one starting electrode? Is the starting gas contains neon-argon like the Philips HPI-BUS?

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

the same way as a Mercury Lamp, yes it has a starting electrode, click on the picture to enlarge it and you will see the starting resistor.

American probe-start MH lamps, don't starts reliably on mercury chokes without a parallel ignitor, despite the presence of the starting electrode. So something additional should be made to lower the starting voltage of the lamp to 240V (Changing the gas filling to neon-argon or using two starting electrodes). Also, see this page .

this is not American it's a European Lamp possibly has a different gas in the arc tube to allow it to strike on a standard Mercury Ballast without a ignitor, also can be used on Ignitor circuits example the Philips HPI Gear, for details see HERE,
