Superimposed ignitor re-fit

Superimposed ignitor re-fit

Lowbay gear tray after a good clean, but I couldn`t get the original 2 wire Philips ignitors for these in time, so went with this set up, but I do prefer superimposed ignitors anyway.

The two wires ignitors, are good mainly for probe-start MH lamps and Philips HPI-T. With a 5KV superimposed ignitor, you can ignite a wider range of pulse-start MH lamps, which 750V is insufficient for them, but it would distroy probe-start MH lamps. I think that HPS lamps can also be ignited by a two wires 750V ignitor. Many types of pulse-start MH lamps, have poor performance on mercury ballast (Osram HQI-BT 400W/D for example would be greenish), and a HPS ballast is recommended.

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.

Yes these are surely better these superimposed ignitors - especially for cable lenghts under one meter between the Ignitor and Lamp.
For standard HPS you need 4-5kV for ignition, and about 2kV for HPS 50-70W.
The high output versions do need a little bit more!

I've only ever seen 2-wire ignitors for LPS/SOX lamps, all the MH/HPS ones I've seen have been either superimposed or impulser types. We don't have probe-start MH over here anyway.

Probe start lamps do not need an ignitor. The starting probe achieves this function (with the shortened lamp life as the cost).

.

They tend to be more common in 120V areas, we don't have them here at all.

Yes. In fact, you do have (lots) of probe start lamps. MV lamps are normally probe start. Usually, the addition of an ignitor to an otherwise probe start circuit in Europe (and in the UK) is for the purpose of running either SON or MH on existing MV gear. In North America, it is common to find probe start MH, however, only on 175W and above. Lower than 175W, they are all pulse start.

I meant probe start MH. All MH here (that I've seen, anyway) is pulse start.

Probe start lamps do not need an ignitor. The starting probe achieves this function (with the shortened lamp life as the cost).

When operating probe-start lamps on 230-240V series choke, this is insufficient for reliable lamp ignition, even with the third starting electrode, so a 750V two wires ignitors is at least still needed.
