What you're seeing is an artifact of flicker in your lighting. Fluorescent and LED lights, much more than incandescent, have a brightening and dimming cycle at 120 Hz (in the US, 100 Hz in some other places with 50 Hz line current). That means that if you shoot at a frame rate of 60 Hz (pretty common for HD video) or 30 Hz (standard resolution, aka "legacy"...

A bit vague to answer... At what ISO setting do your pictures start to degrade? What is the f-number of the lens? What is the slowest shutter speed that you can use? Assuming 400ISO, f/4, 1/60", using this table, you need EV10 at ISO100, so EV8 at ISO400. Then this table gives you the equivalent EV of many light settings. The lumens of a light source don't ...
