I was enquiring more about the lamp fixture,
rather then the lamp itself.
I was trying to work out if the existing fixtures,
are big enough to fit a small,
high output incandesant lamp, in there as well.
In australia it is common to see this done,
in large conference type stadiums.

The most commonly used lamp is the T25.
due to its small size.

We are facing a similar situation.
Just this weekend, we stumbled on a deal too good to pass up. We purchased 24 par cans, a controller, dimmer packs, etc... on craigslist for $500, to use to light the stage. We have Metal Halide "High Bay" fixtures lighting the sanctuary and didn't have anything specifically lighting the stage. The projection screen casts a dark shadow on the stage. Although MH fixtures are more "white" than the MV fixtures mentioned here, they still feel very cold and institutional.
We installed 8 of the cans along the front edge of the stage this weekend, and really like the way it lights the stage.. when the house lights are off.
The problem is, we need some dim light in the sanctuary during worship, and our pastor doesn't stay put behind the pulpit. He usually spends most of the time delivering the message from the walkway between the altar and the first row of seats (actually, we have old pews that were given to us which will be replaced one day, but thats another topic)
We need a way to light the area in front of the stage, but without washing out the screen.
Also, our sound/video booth is upstairs, about 15 feet up, and anything suspended from the ceiling might obstruct the view of the video camera.
Thinking about mounting some flood lights to the walls shining in front of the stage, then maybe doing wall sconces along the walls. It doesn't need to be very bright... We would leave the current lights for situations where we need all the light we can get (such as cleaning).
