Thanks for the reply, interesting, but remember in the "dark" there is still limited light and even darker, deeper shadows.
The "Greenie" night-vision they use, which is similar to old skool military "star-light" vision goggles, also produces odd anomolies(sp?), especially considering most investigators aren't using military-grade night vision goggles. My brother-in-law flies C-17s and he regularly brings home his night vision gear for us to mess around with, it's literally, "night and day" compared to the vision quality you get with most digi-cams.
Hey my friend! Good to see ya posting a decent topic! It's been a while since I've seen one worth commenting on here.

First off, you're absolutely correct about the EMF and "lights" out. In reality if a person want's to cut ALL chances of EMF data contamination the person conducting the research would, as you said, have to cut the master power to the building and/or area they are conducting their research.
Second, the reason the TV shows and media show all investigations, which has set the unfortunate precident for all the "investigators" across the world, is for the entertainment "spook" factor. There is absolutely no data that claims so-called paranormal activity increases at night. It all goes back to the primal and instinctual fear in humans for the absense of light. This was covered in a different topic recently. I posted a lengthy response about scientific research from prominate scientists and psychologists on fear and the instinctual fear humans have.
Summarily, the "darkness" is simpy for entertainment purposes in hopes to create a spook factor that seems to have worked better than any of these media moguls hoped, as now we have thousands of "paranormal investigators" running around catching things that go bump in the night lol.
