It looks like you want to feed some kind of noise function into your light:
Just a note, having looked at the video, that you could probably create a noise profile that would be more natural looking, too. That one looks like they fed it a sine wave with static min/max values. Candles flicker, they don’t phase in and out 
Not being pushy - maybe you want that effect for something else. Just seems like something a little more “flickery” would be better.
