A collection of four modern, minimalist ceiling lights with a sleek design, each featuring a flat, rectangular shape with a smooth, white finish. The lights are arranged in a vertical stack, with each light slightly overlapping the one below it. The lights are depicted against a white background, and below them, there is a color-coded bar graph with four sections, each representing a different wattage: 2500K, 3000K, 3500K, and 5000K.
