It uses 150W metal halide bulb, however its ballast is for 250W bulbs (you can see it on picture #2) ! Strange thing is : Why they use 150W bulb with 250W ballast ? (Typical commercial strategy ?) With this tricky combination; they probably overdriven the lamp (150W to ~200W). And this trick also reduces the bulb life to 6000-8000 hours (original bulb life should be ~12000 hours).
BTW, default ignitor (OSRAM CD-7H) can run 70W-400W metal halide bulbs. 😉
I took the pictures of all the electrical parts;
You can easily see that 250W sign;
This must be ignitor 🙂 ;
But what is this (fuse?) 😀 ;
I did a research with "2501A" input (which is catalog number of the ballast), and I found some info;
So; if I buy a 250W metal halide bulb (with socket components), can I put it directly ? Will it work properly without any modification ? Thx in advance.
P.S. Don't worry about heat, and focal area calibration issue. I'm hoping that I could handle these issues.

An externally hosted image should be here but it was not working when we last tested it.

I don´t understand the idea behind it...
You are saiyng the ally light engine is a 150W lamp overdrived at 250W gear... then what would you win placing a 250W lamp there?
I mean a larger life on the lamp? mmm the 250W lamp arc is larger than the 150W one so I don´t see any benefits there either... maybe some looses if you ask me...
Anyway I am very interested on those kind of information; is is posible for you meassuring the input current to the projector? this could tell you what wattage is being consumed on that system. (mybe the 150W+250W gear runs at somewhere 200W as ally says (if I am not wrong).

no, dont do it, 250W metal halide bulb is too big, although longer life.
the light is same whem the 150W lamp and 250w lamp run in 250 ballast.the watte is same.
but if your LCD is 7", the 150W lamp is brighter
