It's difficult to judge the lighting of a render by what the preview looks like. There's a limitation of 6 or 7 lights that can be displayed in the preview. Your best bet if you think you need a lot of lights is to do low-quality test renders on a small scale. even the 10 or so you mention seems excessive but it will depend on the look you're going for and how bright you have them
