A 3D icon-style illustration of a glowing light bulb with a floating electricity bill labeled "FACTURA ELÉCTRICA", both rendered in clean, smooth plastic materials with soft shadows and modern lighting. The background is a solid deep blue (#0052a4). The design is minimalistic, stylized and polished, resembling a UI icon or app visual. The scene should have soft reflections, gentle ambient occlusion, and subtle volumetric glow from the bulb. No text outside the bill. No human elements. Centered composition. --v 6.1
