i dont have access to anything else, and i really wanna see this thing powered up at somewhat full power, is there a way to do this? if so can someone give me a schematic so i dont end up screwing up?

been having a bit of fun torturing a 100w ballast (ofcourse making sure not to kill it) it really does not heat up at all... lmao and the ingitor starts it easy too, but ofcourse the lamp does not go full bright , it starts up a like a daylight flourescent, slowly warms up to a mercury colour then the center of the tube turns orange, and slowly spreads to the edges at which point it turns a peach colour it is bright to the point of hurting my eyes but i know it can do a whole lot of alot more on higher rated ballasts

if the arc voltage of the 400w HPS and 1Kw HPS is the same, then yes, two ballasts can be operated in parallel with the lamp (granted they are CWA). Only one ignitor need be used.

But I think they are not the same. The US HPS differ (a lot) in the arc voltage among different wattages...

well i think in my case theres only one way for me to find out...

Do it outside so you don't get in trouble when something blows smoke, but it should work but it might not get to full power..

will do.... i will probably do it in a few days, when i get time

Somewhere I read that 1000WHPS lamps run at 200V instead of the 100V 250,400W ones run at.Best just to get the proper ballast.

American S52 1000W HPS lamps, runs at >200V. European 1000W HPS lamps, runs at the same voltage as the 400W and 250W HPS lamps.

alright, yeah i'm kindof broke at the moment, thatas why i was looking for another option, but if it wont work then i'll just wait, not like i actually need the things to turn on, just want them to.

If you just want it to light up then it will probably run on a 400W ballast at close to that wattage, but if you try to drive it harder (ie on two ballasts in parallel) it will cycle.  The American 1000W HPS has an unusually high arc voltage of 250V and needs to be used either on 400V mains, or with a ballast having a sufficiently high open circuit voltage to keep the arc burning.  The reason is because when they developed the 1000W lamp in USA, the designers cut a few corners for speed and simplicity, and just took a standard 400W arc tube and increased its length by approximately 2.5x, keeping the diameter and electrodes the same as the 400W lamp.  This was a quick and easy way to achieve a 1000W lamp, but it has the drawback, due to the very long arc, of running at much higher voltage than other 1000W lamps.
