Thanks,In terms of the light output, since you have one of the lights you're thinking about at your disposal presently, run some test footage and see what sort of camera settings you're getting. Half the luminous flux would correspond to a one stop difference in the required camera settings--either halving the shutter speed, or opening the diaphragm up a stop, or doubling the ISO value used (or some combination of such things). If, for instance, you find that you already have to stop down the lens a lot and you'd prefer to have less depth of field, then less light would hardly be a disadvantage. On the other hand, if your lens diaphragm is already fully open and the shutter speed down around the frame rate and the ISO is high (leading to noisy video), more light would definitely be advantageous.
Needless to say, you can dim lights if they emit too much at full brightness. It's also possible to put an ND filter on the camera to cut down on excess light. Also more lights does mean more flexability in arranging and focusing them, and more time and effort required for that very reason.
I am using a camera with two native ISO one at 400 and one at 1250.
I did indeed stop down and could easily use ISO 400 if I open my lens. I do want high depth of field in the wide shot and low depth of field in the close up shot. So there I am using an ND filter.
Will experiment a bit more. I also got a demo Dedo 650 tungsten. Unfortunately I didn’t get my Rosco color correct gels yet.
It’s a bit overwhelming
