"HQI" is a German system code for a quartz metal halide lamp.

I think that the company (Which is american and not a german company), used the name "HQI", as a generic name for MH lamps, as there are no reasons for non german companies and people to use "HQI" and not "Metal halide lamp". And indeed: In Youtube, I discovered that the term "HQI" is a generic name for a high kelvin MH lamp for uses in aquariums in the US (All Youtube videos of aquariums MH lighting, that described the high kelvin MH lamp inside the aquarium as "HQI" instead as "High kelvin metal halide" or "Aquarium metal halide" in the title, were american videos).

Quote from: BlueHalide on September 18, 2013, 12:46:43 AM One manufacturer claimed that the Advance M80 HQI ballasts were to offer a means of operating a european MH lamp in the US where a CWA wont work (The Advance M80 being a HX-HPF and not CWA). From what I understand Venture is the only company still mfg HX-HPF type ballasts for the US market, and the M80 is not included in their line. Lots of info though I still havent answered my questions. US pulse-start MH lamps, are compatible with the european HPS/MH reactors and european pulse-start MH lamps, are also compatible with the US CWA ballasts for pulse-start MH lamps. Also: http://www.kolmart.com/HID-ANSI-Code-Guide_b_3.html M80 = 250W double ended probe start Metal Halide (Unusual and very rare format. double ended MH lamps almost always comes as pulse start and not as probe-start). Seems that this describes a specific high kelvin MH lamp for aquariums if most MH lamps for this application in the US, are probe-start. Double ended high kelvin MH lamps are also used, which may also be probe-start lamps, and hence the M80 and the "HQI" which is a generic name in the US, for aquarium MH lamps.

I think that by means of M80 for 250W MH lamps, they refering to double ended MH lamps with an Fc2 base like this . Also, beware as unlike in Europe, where HPS and MH ballasts which can operate both type of lamps from the same ballast, when connected to a superimposed ignitor (And only when using semi-parallel ignitor, they are limited to HPS lamps only), in the US, each lamp designed for its own ballast, and you can operate in your S50 only 250W HPS lamps and 250W MH lamps that designed to be operated on this ballast from the begining (Like Venture Whitelux 250W and Philips Retrowhite). Operating your a 250W HPS lamp on an M80 ballast can distroy the lamp. Also, US HPS ballasts, are usually HX and not CWA, and also never heard about HX ballasts for MH lamps.

The M138 look like just the M153 (250W probe-MH), so for a 135V lamp, with an added ignitor. The M80 is really build around the European 90V arc lamps (where the "HQI" came from), so 3A. The difference is not only the output current, but the load characteristic as well: The M80 is a HX autotransformer (with capacitor across the primary just for power factor correction), so the current decreasing with increasing lamp arc voltage (a feature coming from the series reactor and in fact required for thermal stability of many European lamps). It requires the mains voltage to be long time within +/-5% tolerance. The M153 is (mostly) a constant current CWA, so the current remain quite tightly constant over quite wide arc voltage range. And the CWA means, it can tolerate quite some mains variations as well.

@dor, From what I understand, most North American high wattage high pressure sodium ballasts from 150w S56 to 1000w S52 are actually CWA ballasts rarely HX. In addition, a North American 250w S50 high pressure sodium lamp should run decently well on a North American 250w M80 HQI pulse start metal halide ballast because these metal halide lamps are electrically identical to North American 250w S50 high pressure sodium lamps.

Quote from: James on March 15, 2021, 05:11:50 PM HQI is the brand name for Osram quartz metal halide lamps.  In the 250W rating Osram changed its lamps in the 1980s to run at 3.0A vs the more common 2.1A for 250W metal halide lamps.  That helped them attain improved performance.  Actually they run at same current as 250W HPS.  However the HPS ballast cannot be used since the HQI lamp requires an ignitor pulse of higher voltage than the ballast insulation could withstand.  Hence new ballasts for that lamp type were required.  A regular 250W lamp would be significantly overloaded on an HQI ballast. I was wondering if using a regular superimposed ignitor on the 250w S50 high pressure sodium ballast can damage the insulation as well? Are you saying that the OEM ignitor from a North American 250w S50 high pressure sodium ballast will yield a pulse that is too weak to reliably strike the HQI lamp? In my experience, I had no problems igniting an Osram HQI-T 250W/D lamp on a North American 400w H33 HX mercury vapor ballast using an ignitor with added impedance designed to run 250w high pressure sodium lamps on 400w mercury vapor chokes and HX autotransformer ballasts. Here is the link to the aforementioned ignitor: https://www.lighting-gallery.net/gallery/displayimage.php?album=6271&pos=1&pid=195371
