In the video, a person is seen holding a light bulb in their hand. The person then proceeds to screw the light bulb into a socket on the ceiling. The socket is part of a larger light fixture that is attached to the ceiling. The person's hand is visible as they twist the bulb into place, and the light bulb is turned on, illuminating the area around it. The light fixture appears to be a standard ceiling light, and the bulb is a typical incandescent bulb. The video provides a clear view of the process of screwing in a light bulb, and the resulting brightness of the light.
