The lighting is virtually non-existent. You're going to need lights that make flashes if you want to get into portraiture, not the ones that you turn on with a light switch. The reason for that is because you can freeze people with flash, you don't have to use a slow shutter speed to compensate for available, or incidental light.
No, you can't just set your shutter speed to 1/100s and turn on the light switch on and off really fast, despite what you may think, that won't work.
The other thing about flashy lights that make ladies fawn over you, is that the burst of light may be short, but they put out a lot more light than the 60 watt Sylvania's you're using. In turn, making it possible to shoot at f/8 if you want to without having to worry about your shutter speed.
