Easy question:

150 fps.
European 50Hz electricity.
Will i encounter flicker problems with flicker free HMIs and Kinoflos?

:rolleyes:

Probably not.

The Kinos will be no problem but HMIs can suffer from "arc wander." This is generally only an issue at exceptionally high frame rates such at 500fps+, so I don't think you'll have any issue at 150fps.

Hi Mac,

Well thats 1/900 & 1/1800 sec, or equivalent of 450 + 900 fps @ 180. Were they flicker free units?

One even has to start being careful with small tungsten lights above 120 fps @ 180.

Well, i really needed to go fast. Flickering is not too annoying anyway.
I wonder if there is something that could go this fast.

Or any tungsten light 5k or over on AC power will be fine, see the website in my signature for proof of that.
