It seems to have the same ignition correct as any other American ballast would.

How bad is a cycling lamp for a fixture? I have a Hps Wallpak, and the lamp cycles. I think it’s cool looking, but I know it is hard on the components. How bad is it to have it running for maybe 2 or 3 hours?

Inexpensive American luminaire is probably using a tap on the ballast choke to generate HPS HV ignition pulses. So yes, cycling HPS is stressing choke insulation repeatedly. How bad is this in practice, hard to tell, as HPS ignition voltage is typically low, less than 2kV.

Though, looking more carefully, it seems that ignitors should be ES/CT version to have timed cutoff.

ZRM 4.5-ES/C marketed as ignition cut-off, not sure if smart enough to prevent cycling, too.

Ignitor being TOO smart is the source of its problems in practice unfortunately...

@RRK: Are the Tridonic ignitors you got, anti-cycle or regular?

I know once there was a fire caused by neglecting to use a regular not-HV rated cable from ballast box to luminaire in the case of non-igniting MH lamp! So far, so good, ask me how I got four combos of nice NOS Tridonic 150W chokes with nice NOS Tridonic igintors for VERY cheap haha!

We had a rainfall today: https://www.youtube.com/watch?v=YPjPBihIw58
But it is the only one we will have this day.

There are two types of anti-cycle ignitors:
1. One that gives up ignition attempts after few number of cycles.
2. One that monitors the lamp conditions and fires to stabilize a lamp that about to extinguish, and gives up ignition attempts after the lamp extinguished.

If they're series, a retrofit to multiple would be very costly, same goes for restoring 50something luminaires. The replacements look good!
