I have a Venture Lighting UNI-Form PSMH lamp that is rated at 420 watts.  So far, I have not found any gear to support this lamp.  I acquired it from A Walmart parking lot in 2000.  

The Color comes out as a Cream-White color, not very common back then.  (White with a tinge of Yellow)

This is a typical color of a new Na-Sc MH lamp.

I was asking more about the commonality of the supportinn gear.  Ballast/Ignitor/Capacitor

I would expect it to work on a regular either "400W pulse MH" or "400W HPS" ballast, just has a bit higher arc voltage, so yielding higher real power transfer to the lamp.
Venture is doing these things: Sell two lamp lines with different real power designed for common ballast type - one lamp type is usually 5..10% above the "official" ballast rating, other usually 10..15% below (usually 340..360W for a 400W ballast). On the lamp they usually specify the real power transfer, not the standardized ballast rating...
One version is intended as an energy ssver, other as lumen boost for the same fixture...

But I do not know this type, if it is designed for a HPS or pulse MH ballast...

This lamp operates on a lag regulated ballast made solely by Venture, Venture doesn't list this lamp anymore in their "uni-form pulse start series" catalog, so they likely discontinued this lamp. Come to think of it, I haven't seen these in awhile too. But I distinctly remember fixtures using these lamps had a specific 420w ballast made by Venture. One electrical website lists its ANSI code as M147, though when I searched M147, got no results. I have not seen anywhere that this lamp is compatible with 400w PSMH (M155) gear, but as Medved said, it should work fine with no problems, ballast just my run slightly warmer. May also be compatible with venture's 450w (M144) ballast, but not sure

It is a PSMH lamp.  The fixture it came from was a Cooper/Crouse-Hinds (IIRC).  This particular lamp has never been lit, but I sure would like to one fine day.

The lamp is indeed an PSMH, but the question is, whether it isn't meant as a retrofit into HPS fixture, so then to operate on a HPS ballast, many makers sell such products...


But as BlueHalide wrote, it could well be a non-ANSI proprietary lamp, needing proprietary ballast (and I have no idea, how different spec that is compare to some standardized one).
The even nonstandard wattage lamps (e.g. 360W), when designed for some standardized ballast (e.g. M155), the lamp etch then uses to list "360W, ANSI M155" or similar way (for that example; namely Venture had many such products).
On this lamp I do not see any link to any standardized ballast code, so unless it is mentioned on the box, leaflet or any documentation, it could well be part of a non standardized proprietary system.

Venture Uniform Pulse-Start + Non standard ANSI wattage = Special Ventronic electronic ballast. I encountered this in Venture website a lot of times. This is the same case as Philips Cosmo MH lamps: Non standard wattage = Special electronic ballast.

When these were first powered on, it took about 45-60 seconds from strike to reach full brightness.  I was impressed.  I'm sure it is a Venture proprietary deal, as the lamp came pre-installed in the luminaire.  I was just an evil little jerk and stole this some 16 years ago.  I have no idea what they replaced it with; if they had to special order another lamp.  What I wonder is what they relamp the fixture with now.  I will say that the fixture was way too light and small to contain a magnetic ballast.

You stole it?

This wattage is in fact completely omitted from Venture's website, catalog, and even any archived data sheets, there literally is nothing on this product. I have a feeling, like others have said above, it was a promotional proprietary product by venture to be only operated on the their own matched ballast, which is also non-existent online. Venture made a probe start 850w 5000K lamp in the early 2000s to be a high CRI direct replacement for 1000w M47 sportslighting, that lamp also vanished out of production as quickly as it started. Im sure theres dozens of commercially produced lamps and ballasts by Venture that only existed a short while

So what would they re-lamp these with then?  LEDs?

Yeah, I was probably 13-14 years old and a pretty bad kid.  I taught myself the error of my ways though.  I wasn't half as bad as the other neighborhood kids who would destroy the neighborhood streetlights though.  But I still don't justify today what I did as a teenager.

How did they destroy them?

Any existing fixtures using Venture's 420w ballast will need to get reballasted, however im sure most will just get relamped with 400w lamps. Ive seen plenty of Venture fixtures (particularly their 320w PSMH systems) get spot relamped (and even group relamped at times) with regular 400w lamps.
