Thanks so much Dom! that is super helpful! I had to read your answer and your older post about metering several times but it's finally starting to click.
What I meant about the flickering is, since I will be working no/low-budget, I will likely be using these RGB LED smart bulbs I have at home in various setups, and when they are dimmed, they can cause an intense flicker I found when shooting my mirrorless cameras. I was asking if using the mirrorless cameras at 24 fps would accurately represent how the lights may be captured on film running at the same rate. I've done some reading on the subject and it seems the best bet is to never dim them because the "refresh rate"(?) for lack of a better term, becomes very visible. Keeping them at full blast and using diffusion and bounce cards as needed seem like a clear fix. My inexperience is showing haha.
As a tech, what are your first guesses when a Bolex motor is jammed? I bought an original Reflex a couple weeks back for cheap "As Is" because I could see it was cosmetically pristine and might only need CLA, I've heard stuck motors are pretty common.
