Here is my AEG Koffer 250 open. THe ballast and ignitor is made by BAG. The ignitor has a glowstarter in it, and i have never seen that before. The capacitors are made by ITT. I have rewired the whole fizture and cleaned it because it was full of crap.

Most HPS Koffer 150 and 250 we have, uses electronic ignitors, either low frequency pulses or superimposed. You can see the two types in different AEG Koffers with cycling HPS lamps here .
The optics looks exaclty like our Koffer 150 at Qiryat Ata, so it is designed for elliptical diffused HPS lamps.
Is the glow starter in your ignitor have a thermal cutout in case of a power dip that extingush the lamp or cycling lamp? The glow starter wears considerably during lamp hot restrike and most internal ignitor HPS lamps have a thermal cutout for their inernal glow starters.

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.

It is a capacitor in the glowstarter, so i Think it is a sort of thermal cutout. On the road wher this one were mounted, it was Koffer 250 with both HPS and MV. So maybe the ignitor is newer than the ballast. And the bulb is quite new.

What is that microswitch looking thing next to the lamp ?

The capacitor in the starter - And a bigger one in the ignitor block itself - are just capacitors. I dont think this system have any means of cutout when the lamp cant start

The capacitors appear to be leaking a bit.. (all that dirty area on the metal near the terminals). Maybe internally they are ok, but the dirt attracted to this oil may eventually let some leakage current on the outside, through the dirt between the terminals or terminal to capacitor casing. It'd be good to take off the terminals and give everything a good clean

@Ash: I think the microswitch is for the safety feature to cut the circuit when opening

Pretty, please no more Chinese failure.

The microswitch cuts the circuit when you take off the bowl. I have cleaned the capacitors as best i can, and it's no current leaking because the RCD doesn't react when the lantern goes on.

I guess you need to get rid of those leaked PCB capacitors since they are not very nice for your health. Nice fixture anyway...

The capacitors are not leaking, that is just dirt

I guess your lantern is made in the 70's. It is strage that yours have BAG Turgi Ignitor with St 501 Starter and Ballast. My Koffer is made in 1972 and has a very early superimposed electronic ignitor which is original to the fixture.

See here for the Swiss version of the Koffer 250 (Quadralux -G) ballast compartment. http://www.lighting-gallery.net/gallery/displayimage.php?album=533&pos=51&pid=36664
