hello,
the attachment shows my problem. i need a light which has a big volume in a
closed room, but it can be realized neither with many point-lights
(rendertime) nor with area-lights. which are my keywords i have to search
for (me: non-english) or does anybody know a solution?
thank you for hints.

All I can think of is radiosity, might be hard to get quality results
though.

white long thing on the right side).

In theory radiosity would be the solution but I would try
several area lights or just many point lights.

If you put a white object where you want your light source, you can make
radiosity treat it like a light source. You will see illumination from it.

the best result is this.
i used radiosity, ambient and area_light.
but it does not look realistic.

Maybe you could try taking away the lights completely and just using high
ambient values and radiosity.

Into the finish of the white object, yes. And with a high value for
white of it is any distance away. People who use it more can probably tell
you more about making it look good.
Here is what I used for my test before telling you that it would work.
cylinder {
-3*z, 3*z, .5
pigment { rgb 48 }
finish { ambient 1 }
translate < 3.0, 5.0, 0.0 >
}
