Philips SN61 starter for HID lamps. These came from Philips SGS201 fixtures and where used to start 100W SON-T lamps. These have seen extensive use and have been in service every night since 1988 until about three months ago. To the right the innards of a smashed open unit. The information labels on these where paper and are long gone.

Screw terminal connections.

Oh, I forgot about these CMOS 4000's series IC

4093: Quad 2-input NAND gate, schmitt trigger inputs
4060: 14-stage binary ripple counter and oscillator, schmitt trigger inputs

Pretty, please no more Chinese failure.

What may be the purpose of these logic chips? Are they some form of timer or striking attempt counter for some kind of EOL protection?

Too many things are secret. Only open information can really preserve old technology.

I like fluorescent and other conventional lighting and old electronic equipment. Today's things are not made to last.

Looks like an anti-cycling ignitor. These stop their operation after a number of cycles, or when the lamp didn't struck.
I didn't know that Philips made anti-cycle ignitor in this time.
