Will the attached 100Hz flickering light output cause a problem for CCTV?

Thanks, thats 16ms approx exposure time.
Do you know what proportion of CCTV camers in use at night (in say city centres) go below 10ms exposure time?
And how many go below 5ms exposure time?

Lots. Most cameras will wind the exposure time down as far as 1/10000 to control exposure. Cheaper cameras with smaller imagers are pretty insensitive and want lots of light though,so will struggle to go below 1/60 at night. Plenty will though.

Frankly I think you're approaching the problem from the wrong end, but that seems to characterise most of your posted topics on this board.
