While 2 85W lightbulbs seem like a lot of light, it is likely that the biggest variable is the ambient light in your scene...ie. other lights and windows in your room. Also, continuous light (I assume) is fine for video, but you should consider flash for product photography.
Echoing @Micheal C below, by controlling your light, you can ensure that your shots 'look' the same from shot to shot, and that will also result in your shooting conditions (exposure, focal length, etc) are the same shot to shot.
Pro setups use large output flashes (250W or more) that essentially overpower any ambient, leading to consistent light, shot to shot. (Many pro shooters also shoot in nearly dark studios as well for much the same reason.) They also use multiple flash units (and modifiers) to fill and balance the shot, removing shadows or adding subtle shadows as needed.
Check out AlienBees or Prophoto flash units to see just two examples.
You can also achieve better results using multiple speedlight camera flashes such as the Canon Speedlite series. By using them off camera with the built in remote flash, and adjusting the power of each, you can achieve quite (mostly) repeatable results.
