C100 Mark ii Light Flicker?

Hi wondering if anyone can help me.
I was filming a gig last night and the lighting was a pretty horrible blue / pink but nothing out of the ordinary, I noticed I was getting a really nasty strobing flicker, usually as with projectors / monitors etc I would just change the shutter speed and that does the trick but no matter what shutter speed I changed it to the flicker was still there!
(I even played around with the in camera flicker reduction which did nothing)
I have had my C100 mark II pretty much since it came out and this is the first time this problem has occurred.

I was shooting PAL 1920x1080 25P 1/50th - Wide DR PP

If anyone could shed some light on this I would be greatly appreciative

Were you shooting PAL projectors (running at 25 fps) or NTSC projectors (running at 23.976 fps and/or 24p and/or 29.97 fps and/or 30p and/or 60i and/or 60p)?

Hi sorry there weren't any projectors I was just using that as an example of the kind of flicker I was getting.
The lighting set up was a mixture of old school looking par cans, a couple of multicoloured LED lamps and a gobo

Some LEDs have lots of flicker. If they are not designed for cine lighting, there is absolutely no telling what their flicker rate is or whether you can cure it. Indeed, so bad is the flicker problem with consumer-grade LEDs that they have simply stopped bothering to report flicker statistics at all, and rather leave it up to the end user to do their own tests: http://www.archlighting.com/technology/leds-fighting-flicker_o
