Yes, if you raise the framerate you lose light: because the shutter is faster (if you're using a real 180º shutter and not DSLR style shutter speed in fractions of a second). Faster shutter, less light.
what do you mean if you're using a real 180 degree shutter digital works the same way. The more you lower your shutter the less light hits it.
If you set your shutter speed as a fraction of a second, it doesn't automatically change when you change your frame rate (unless, I suppose, that shutter speed is impossible at that frame rate). If you set it in degrees, it is by definition directly related to the frame rate: 180° shutter means that the shutter is open for exactly have the frame duration.
