Cats generally sleep during the day and are more active at night. Even if a pet cat can't sleep at night, there's no need to turn on the lights, as it can clearly see the room. Turning off the lights at night helps cats establish their own sleep-wake cycle by clearly distinguishing between day and night. Keeping the lights on all the time will prolong the daytime and prevent the cat from relaxing. Following natural rhythms and turning off the lights at night is better for cats. However, if a newly adopted kitten is not yet used to its new environment and is timid, turning off the lights at night may make it more anxious and unable to rest properly. In this case, you can leave a warm light on for the kitten; it won't be too bright but will clearly illuminate its surroundings, making the kitten feel safe.
