I know you are joking, but humans are terrible at guessing brightness. A living room that appears brightly lit by an artificial light is still about 100 times dimmer than direct sunlight on a summer day
500 lumen per square meter is plenty for a living room, but in my grow tents I'm running 50000 lumen per square meter, which still gives me a lower brightness than direct sunlight
