Can i use this ballast? (wanna build a 5500 lumen projector)

[The Alchemist]

Hi I bought a 70w MH ballast (only 5 euro (~5 dollar)) and I want to use it for building my projector. I have been reading for a while and i think I am ready for it.

My goal is a 60"-70" projection. Thats 12 square feet of surface. I red somewhere that 16-18 lumen per square feet is enough light, so thats 12x18= 216 lumen. 10% light will pas through the LCD and optics so I need at least 2200 lumen. A 70 watt MH give's off 5500 lumen so that has to be enough.

Now my problem's:

First:
I have bought the ballast without a bulb and I don't know if i can radomly pick a 70W MH bulb and attach it. So my question to you is, can i buy just any lamp?

Some pictures:



The closed ballast




The top and bottom of the opened ballast, you can see the transformator, condensator and the ignitor.


The information on the trafo. So if i read it right I can use any 70w bulb, or does TS mean that i can only use double ended lamps?


The plug.

Ok my second question:
Where can i find the Rsx7 feet, here in europe?

My last one:
I know 640x480 or 800x600 will give the best results, but has anyone got pictures of there lower resolution projections? Will it be good enough for 60"? (I want to watch movies)

Thanx.

Can nobody help me?

I know it can be done with 70w

I've tried my prototype with 70w MH (returned it as was planning). Maybe my box was not that good with light stopping and reflector was not the one I should have used and I didn't use condenser lens but with Spectra C image was way, way too dark. Better than with 300W halogen though.

anyways there were no question for me that messing with 70W MH will be just waste of time.
