I using vertical lamp house with Osram XBO 1600W/OFR lamps and 380mm mirrrors, i know standard procedure for align a lamphouse, but i'm interested are they any special procedure about align these lamp houses???

Another question is this, can the picture be un sharp (expecial in scope) if lamp house is not properly align??, and what is difference using a 380mm and 350mm mirrors with 1600W bulbs, because in one setup are XBO 1600W/OFR bulbs with 380 mirrors, and in other setup are XBO 2500W/OFR bulbs with 350mm mirrors, and what are proper bulb for 33 meter long projection and 9 meter width screen bulb be ok, and what for 50 meter long and 16 meter width screen bulb be ok???, and one thing more does is ok to XBO1600W/OFR operating at 80A???

Thanks, Marin

Lamphouse alignment effects focus

The mirror has to be the one specified for the lamphouse to work correctly since the lamp has to be located at its focus point

You don't specify the make of lamp house
