Hello all:
I recently seen a pink MH lamp cycling, which I suspects that it is a probe-start MH lamp operating on an M59 ballast and I did a two part video . For about 13:00 mins after extingushing, there was nothing, than a secs or so after pressing the rec button to stop recording the video, the lamp abruptly restruck from nothing (No glow, nor flashes or an aux discharge). The color of the light was similar to when the lamp cold starting.

In Eltam factory and in Leo-Beack high school, this wasn't the case. I've seen in Eltam, the Osram HQI 400W/N/SI which it had an aux arc after 4 mins from cycling the power, flashed once, then appeared for several mins and then appeared for 4 mins until the lamp restruck after 9 mins).

In Leo-Beack, the total length of the hot restrike of the probe-start MH lamps on the M59 autoregulator ballasts, was 5 mins, and there were blue aux arcs in them before the restrike.

However, in the said pink MH lamp (Which I think that it is a probe-start MH lamp), I don't seen any aux arc at all before the lamp restruck. The lamp simply hot restruck without an aux arc appearing.

I know that there is a bi-metal that short-circuits the starting probe, after the lamp warms up, and so prevent the voltage that required to build the aux arc, but usually it is released when the arctube still not ready to be restarted, so the aux arc appears.

Are there members (Mainly american members) here that owns probe-start MH lamps, and  experienced an abrupt hot restriking of their lamps without an appearance of an auxiliary discharge between the main and the starting electrode at all before the hot restrike of their lamps (Hot restrike from a total darkness)?

Yes, Ive seen several lamps do this, all were of lower wattage however. 175w Probe start lamps seem to be the most notorious for hot restriking without any signs of life before restrike, just completely dark, then ignition. In one case of this I suspected a misapplication (a probe start lamp in a pulse start fixture) It ended up being a probe start fixture but what was even more intersting was the fact that the lamp operating in it had a broken lead to the starting probe electrode (broke off at the resistor in the lamp), the main electrodes were only connected and would hot restrike after about 10 mins on a standard probe start ballast. This lamp is well aged too as the arc tube is almost completely black. Its a Venture brand lamp, so either the ballast has unusually high OCV or the lamps gas fill requires a very low voltage for ignition.

Electronic ballasts and some ignitors are on purpose designed to reignite the lamp this way: After detecting the missing arc, the ballast shut down (and ignitor stop pulsing) and wait for some time (assumed to be sufficient for the lamp to cool down) and then restart the lamp.
The reason for such design is the extra electrode wear caused by the unsuccessful ignition attempts, so such timer in fact prolong the lam life, when the lamps are frequently subjected to voltage dips or so, causing the lamps to extinguish
But as it is a probe start lamp, I doubt there would be any electronic ballast. What could be there (as it is a 230V region), is the intelligent 750V ignitor, incorporating that feature.

Medved: We have no 750V ignitors in Israel. So I'm sure that it is operated on an M59 autoregulator ballast.
There is a video here in LG, of a hot restrike of a Philips HPI-BUS burning horizontally, which shows the aux discharge before the hot restrike as well. But the specific pink MH lamp I've seen (Which I think it is a probe-start MH lamp), wasn't the case, and was simply hot restruck from a total darkness.
