Do Self-ballasted HPS lamps exist??? « on: December 19, 2018, 05:40:02 AM » Author: mefurd98
Did they ever produce a SB-HPS lamp? I have not heard of one...I was just wondering. Undecided Undecided

Unless the ballast is some electronic which is able to maintain the arc and so overcome the zero crossing extinction, the characteristics of the HPS and MH do not allow the operation on just a resistive ballast.
As was already described around the previous posts with the same question, the MV has an unusualy long ionization life and allows for an active (so all the time fed via its resistor) auxiliary probe, both are enablers for the discharge with a plain resistive ballast.

More details find in all the other instances of the same question ("Are there any selfballasted MH/HPS", "Why are there no selfballasted MH" and so on) in the Forum...

Although I'm not disagreeing with Medved, at all, I have seen somewhere on LG a self ballasted lamp very much similar to HPS. It
produces more of a white light than the typical HPS though. Heck, I'm not sure if it's related to HPS, or LPS. There's a name for it,
and unfortunately I don't remember what it's called. But it's definitely a sodium lamp of some sort.
There is a user on here that uploaded a picture and even a video of it a while back. The ballast within the screw-in adapter,
was magnetic.

The said lamp that was made by European Sylvania, isn't a self-ballasted HPS lamp, but a HPS retrofit for European 230-240V mercury chokes. It had an internal inductive to allow its current to be the same as the 125W or 80W MV lamps that it is intended to replace, and an internal glow starter.
Sylvania now produces a CMH lamp with a similar configuration, after the EU banned mercury lamps and retrofit HPS lamps: http://www.lamptech.co.uk/Spec%20Sheets/D%20MHC%20Sylvania%20Relumina%2085W.htm

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

If I can find the picture of it on LG, I'll post a link to it, unless someone finds it before I do lol
But I'm having a tough time finding the picture and video.
I think you're correct Dor123, but I'll still look around for it.

@Dor123, very similar, but not quite the same. However, you have seen the lamp that I'm talking about.
It was THIS lamp: https://www.lighting-gallery.net/gallery/displayimage.php?album=2692&pos=7&pid=130696
