No, I light it by the monitor with the camera set to 500 asa. I will tell my gaffer that we need to get to x number of foot candles for the keys, and he will prelight with a meter to get in the ball park. The camera is it's own best meter. I think that when set to 500 asa the camera behaves how I would expect a 500 asa film stock or video camera to behave. I use the same instruments that I would on anything else, and get comparable results.
I once showed up for a large night exterior for which we were already slightly under powered (2 x 4ks, a couple of 9 lights and a few 1200s and 575s to light about 2 blocks of street), when the director decided the whole scene would be much better in slow motion. I had to go to 800 asa, and this was back on build 17, and the stuff came out looking great, again, you just have to have solid blacks.
