A blank, white square tile ceiling, each with a single light on it. The tiles should be arranged in a symmetrical pattern, with the lights facing upwards and directly towards the camera. Each tile is uniform in size and shape, with no shadows or reflections visible on them. This background will provide a clean and uncluttered space for creative design elements to be placed on the empty area of one wall. No other objects can be seen within the scene, emphasizing the simplicity and clarity of the lighting layout. --ar 67:45 --style raw --s 50
