High-CRI LED lighting is about ten times as efficient as the old film-making standard of incandescent lighting. Inverse square law affects incandescent lighting in exactly the same way, but they still managed to shoot indoor scenes at 24fps using it. Switching incandescent lighting for LED, keeping light locations and power use the same, will make every point about 10 times brighter than it was before. Therefore LED lighting is enough to shoot at about 240fps.
