At high speed the camera requires a good amout of light. I can't tell you the exact amount of candle power required. You could ask the people at CASIO. Figure the image will look 1/2 to 1/3 as bright as the actual lighting indoors. I would think one or two 150W painters floodlights would work although I have not tried it as yet. Indoors with daylight shining through a window works fine.
