Well I took this outside in the garage and did some testing off the 220V. The 150w osram powerball gets blinding bright out of the stock reflector.

I think the arc is too big to be focused properly. Its odd I placed a white object about 1 inch from the reflector and it was blinding bright. I think the LCD projectors still need a point source when I tested in a projector it was very dim compared to an auto hid with a much smaller arc gap. I was assuming that these projectors just needed the light area flooded and the lenses took care of the rest.

Hello,

I need to use the ballast from my old IBM ilc200(lp530 projector's clone) without the rest of this projector.

So, I want to extract the IBM's ballast and use it with a diypro.us bulb for a other application.

I think it's possible, but I don't know which opto to bypass...
Can you help me please ?
(sorry for my english )

Sebka33, from France.

how did u guys bypass the switch to turn onthe ballast independently? im currently in the same pickle but need to test a used ballast to see if it works, btw, how much of a difference did u see before and after the focused point? i too thought you only needed to flood the lens with light

These ballasts dont work well with large arc gaps. They have very sensitive current sensing. Someone needs to figure out how to change the current and wattage to make it adjustable.
