Cinematography - Lightning

I came up with an idea to make the lightning seem realistic. My initial idea was to do it entirely in post, but I quickly realized that it wouldn't look real, and I wanted something that looked professional and cinematic, although I'm starting to realize that not many people in the crew really care for cinematics ;)

So my fool proof idea was to actually flicker the lights. The way that I did this is to use my 105 W CFL as the lightning. I keep this light constantly lit from the direction of the windows. Then I flicker all other lights (2 V Lights and 1 Rifa). Then in post, in the frames where the key lights are off I will bump up the exposure to make it look very bright. Since these frames are only lit by the blue CFL from the side of the windows, they will look like realistic lightning.
